General information
|
||||
|
||||
What is the relationship between GCC and EGCS?
|
||||
|
||||
In 1990/1991 gcc version 1 had reached a point of stability. For the
|
||||
targets it could support, it worked well. It had limitations inherent
|
||||
in its design that would be difficult to resolve, so a major effort
|
||||
was made to resolve those limitiations and gcc version 2 was the
|
||||
result.
|
||||
|
||||
When we had gcc2 in a useful state, development efforts on gcc1
|
||||
stopped and we all concentrated on making gcc2 better than gcc1 could
|
||||
ever be. This is the kind of step forward we wanted to make with the
|
||||
EGCS project when it was formed in 1997.
|
||||
|
||||
In April 1999 the Free Software Foundation officially halted
|
||||
development on the gcc2 compiler and appointed the EGCS project as the
|
||||
official GCC maintainers. The net result was a single project which
|
||||
carries forward GCC development under the ultimate control of the
|
||||
[36]GCC Steering Committee.
|
||||
_________________________________________________________________
|
||||
|
||||
What is the relationship between GCC and Cygnus / Red Hat?
|
||||
|
||||
It is a common mis-conception that Red Hat controls GCC either
|
||||
directly or indirectly.
|
||||
|
||||
While Red Hat does donate hardware, network connections, code and
|
||||
developer time to GCC development, Red Hat does not control GCC.
|
||||
|
||||
Overall control of GCC is in the hands of the [37]GCC Steering
|
||||
Committee which includes people from a variety of different
|
||||
organizations and backgrounds. The purpose of the steering committee
|
||||
is to make decisions in the best interest of GCC and to help ensure
|
||||
that no individual or company has control over the project.
|
||||
|
||||
To summarize, Red Hat contributes to the GCC project, but does not
|
||||
exert a controlling influence over GCC.
|
||||
_________________________________________________________________
|
||||
|
||||
What is an open development model?
|
||||
|
||||
We are using a bazaar style [38][1] approach to GCC development: we
|
||||
make snapshots publicly available to anyone who wants to try them; we
|
||||
welcome anyone to join the development mailing list. All of the
|
||||
discussions on the development mailing list are available via the web.
|
||||
We're going to be making releases with a much higher frequency than
|
||||
they have been made in the past.
|
||||
|
||||
In addition to weekly snapshots of the GCC development sources, we
|
||||
have the sources readable from a CVS server by anyone. Furthermore we
|
||||
are using remote CVS to allow remote maintainers write access to the
|
||||
sources.
|
||||
|
||||
There have been many potential GCC developers who were not able to
|
||||
participate in GCC development in the past. We want these people to
|
||||
help in any way they can; we ultimately want GCC to be the best
|
||||
compiler in the world.
|
||||
|
||||
A compiler is a complicated piece of software, there will still be
|
||||
strong central maintainers who will reject patches, who will demand
|
||||
documentation of implementations, and who will keep the level of
|
||||
quality as high as it is today. Code that could use wider testing may
|
||||
be integrated--code that is simply ill-conceived won't be.
|
||||
|
||||
GCC is not the first piece of software to use this open development
|
||||
process; FreeBSD, the Emacs lisp repository, and the Linux kernel are
|
||||
a few examples of the bazaar style of development.
|
||||
|
||||
With GCC, we are adding new features and optimizations at a rate that
|
||||
has not been done since the creation of gcc2; these additions
|
||||
inevitably have a temporarily destabilizing effect. With the help of
|
||||
developers working together with this bazaar style development, the
|
||||
resulting stability and quality levels will be better than we've had
|
||||
before.
|
||||
|
||||
[1] We've been discussing different development models a lot over
|
||||
the past few months. The paper which started all of this introduced
|
||||
two terms: A cathedral development model versus a bazaar
|
||||
development model. The paper is written by Eric S. Raymond, it is
|
||||
called ``[39]The Cathedral and the Bazaar''. The paper is a useful
|
||||
starting point for discussions.

|
||||
How do I report a bug?
|
||||
|
||||
There are complete instructions [40]here.
|
||||
_________________________________________________________________
|
||||
|
||||
How do I get a bug fixed or a feature added?
|
||||
|
||||
There are lots of ways to get something fixed. The list below may be
|
||||
incomplete, but it covers many of the common cases. These are listed
|
||||
roughly in order of increasing difficulty for the average GCC user,
|
||||
meaning someone who is not skilled in the internals of GCC, and where
|
||||
difficulty is measured in terms of the time required to fix the bug.
|
||||
No alternative is better than any other; each has its benefits and
|
||||
disadvantages.
|
||||
* Hire someone to fix it for you. There are various companies and
|
||||
individuals providing support for GCC. This alternative costs
|
||||
money, but is relatively likely to get results.
|
||||
* [41]Report the problem to the GCC GNATS bug tracking system and
|
||||
hope that someone will be kind enough to fix it for you. While
|
||||
this is certainly possible, and often happens, there is no
|
||||
guarantee that it will. You should not expect the same response
|
||||
from this method that you would see from a commercial support
|
||||
organization since the people who read GCC bug reports, if they
|
||||
choose to help you, will be volunteering their time. This
|
||||
alternative will work best if you follow the directions on
|
||||
[42]submitting bugreports.
|
||||
* Fix it yourself. This alternative will probably bring results, if
|
||||
you work hard enough, but will probably take a lot of time, and,
|
||||
depending on the quality of your work and the perceived benefits
|
||||
of your changes, your code may or may not ever make it into an
|
||||
official release of GCC.

||||

|
||||
Does GCC work on my platform?
|
||||
|
||||
The host/target specific installation notes for GCC include
|
||||
information about known problems with installing or using GCC on
|
||||
particular platforms. These are included in the sources for a release
|
||||
in INSTALL/specific.html, and the [43]latest version is always
|
||||
available at the GCC web site. Reports of [44]successful builds for
|
||||
several versions of GCC are also available at the web site.
|
||||

||||
|
||||
Installation
|
||||
|
||||
How to install multiple versions of GCC
|
||||
|
||||
It may be desirable to install multiple versions of the compiler on
|
||||
the same system. This can be done by using different prefix paths at
|
||||
configure time and a few symlinks.
|
||||
|
||||
Basically, configure the two compilers with different --prefix
|
||||
options, then build and install each compiler. Assume you want "gcc"
|
||||
to be the latest compiler and available in /usr/local/bin; also assume
|
||||
that you want "gcc2" to be the older gcc2 compiler and also available
|
||||
in /usr/local/bin.
|
||||
|
||||
The easiest way to do this is to configure the new GCC with
|
||||
--prefix=/usr/local/gcc and the older gcc2 with
|
||||
--prefix=/usr/local/gcc2. Build and install both compilers. Then make
|
||||
a symlink from /usr/local/bin/gcc to /usr/local/gcc/bin/gcc and from
|
||||
/usr/local/bin/gcc2 to /usr/local/gcc2/bin/gcc. Create similar links
|
||||
for the "g++", "c++" and "g77" compiler drivers.
|
||||
|
||||
An alternative to using symlinks is to configure with a
|
||||
--program-transform-name option. This option specifies a sed command
|
||||
to process installed program names with. Using it you can, for
|
||||
instance, have all the new GCC programs installed as "new-gcc" and the
|
||||
like. You will still have to specify different --prefix options for
|
||||
new GCC and old GCC, because it is only the executable program names
|
||||
that are transformed. The difference is that you (as administrator) do
|
||||
not have to set up symlinks, but must specify additional directories
|
||||
in your (as a user) PATH. A complication with --program-transform-name
|
||||
is that the sed command invariably contains characters significant to
|
||||
the shell, and these have to be escaped correctly, also it is not
|
||||
possible to use "^" or "$" in the command. Here is the option to
|
||||
prefix "new-" to the new GCC installed programs:
|
||||
|
||||
--program-transform-name='s,\\\\(.*\\\\),new-\\\\1,'
|
||||
|
||||
With the above --prefix option, that will install the new GCC programs
|
||||
into /usr/local/gcc/bin with names prefixed by "new-". You can use
|
||||
--program-transform-name if you have multiple versions of GCC, and
|
||||
wish to be sure about which version you are invoking.
|
||||
|
||||
If you use --prefix, GCC may have difficulty locating a GNU assembler
|
||||
or linker on your system, [45]GCC can not find GNU as/GNU ld explains
|
||||
how to deal with this.
|
||||
|
||||
Another option that may be easier is to use the --program-prefix= or
|
||||
--program-suffix= options to configure. So if you're installing GCC
|
||||
2.95.2 and don't want to disturb the current version of GCC in
|
||||
/usr/local/bin/, you could do
|
||||
|
||||
configure --program-suffix=-2.95.2 <other configure options>
|
||||
|
||||
This should result in GCC being installed as /usr/local/bin/gcc-2.95.2
|
||||
instead of /usr/local/bin/gcc.
|
||||
_________________________________________________________________
|
||||
|
||||
Dynamic linker is unable to find GCC libraries
|
||||
|
||||
This problem manifests itself by programs not finding shared libraries
|
||||
they depend on when the programs are started. Note this problem often
|
||||
manifests itself with failures in the libio/libstdc++ tests after
|
||||
configuring with --enable-shared and building GCC.
|
||||
|
||||
GCC does not specify a runpath so that the dynamic linker can find
|
||||
dynamic libraries at runtime.
|
||||
|
||||
The short explanation is that if you always pass a -R option to the
|
||||
linker, then your programs become dependent on directories which may
|
||||
be NFS mounted, and programs may hang unnecessarily when an NFS server
|
||||
goes down.
|
||||
|
||||
The problem is not programs that do require the directories; those
|
||||
programs are going to hang no matter what you do. The problem is
|
||||
programs that do not require the directories.
|
||||
|
||||
SunOS effectively always passed a -R option for every -L option; this
|
||||
was a bad idea, and so it was removed for Solaris. We should not
|
||||
recreate it.
|
||||
|
||||
However, if you feel you really need such an option to be passed
|
||||
automatically to the linker, you may add it to the GCC specs file.
|
||||
This file can be found in the same directory that contains cc1 (run
|
||||
gcc -print-prog-name=cc1 to find it). You may add linker flags such as
|
||||
-R or -rpath, depending on platform and linker, to the *link or *lib
|
||||
specs.
|
||||
|
||||
Another alternative is to install a wrapper script around gcc, g++ or
|
||||
ld that adds the appropriate directory to the environment variable
|
||||
LD_RUN_PATH or equivalent (again, it's platform-dependent).
|
||||
|
||||
Yet another option, that works on a few platforms, is to hard-code the
|
||||
full pathname of the library into its soname. This can only be
|
||||
accomplished by modifying the appropriate .ml file within
|
||||
libstdc++/config (and also libg++/config, if you are building libg++),
|
||||
so that $(libdir)/ appears just before the library name in -soname or
|
||||
-h options.
|
||||
_________________________________________________________________
|
||||
|
||||
GCC can not find GNU as/GNU ld
|
||||
|
||||
GCC searches the PATH for an assembler and a loader, but it only does
|
||||
so after searching a directory list hard-coded in the GCC executables.
|
||||
Since, on most platforms, the hard-coded list includes directories in
|
||||
which the system asembler and loader can be found, you may have to
|
||||
take one of the following actions to arrange that GCC uses the GNU
|
||||
versions of those programs.
|
||||
|
||||
To ensure that GCC finds the GNU assembler (the GNU loader), which are
|
||||
required by [46]some configurations, you should configure these with
|
||||
the same --prefix option as you used for GCC. Then build & install GNU
|
||||
as (GNU ld) and proceed with building GCC.
|
||||
|
||||
Another alternative is to create links to GNU as and ld in any of the
|
||||
directories printed by the command `gcc -print-search-dirs | grep
|
||||
'^programs:''. The link to `ld' should be named `real-ld' if `ld'
|
||||
already exists. If such links do not exist while you're compiling GCC,
|
||||
you may have to create them in the build directories too, within the
|
||||
gcc directory and in all the gcc/stage* subdirectories.
|
||||
|
||||
GCC 2.95 allows you to specify the full pathname of the assembler and
|
||||
the linker to use. The configure flags are `--with-as=/path/to/as' and
|
||||
`--with-ld=/path/to/ld'. GCC will try to use these pathnames before
|
||||
looking for `as' or `(real-)ld' in the standard search dirs. If, at
|
||||
configure-time, the specified programs are found to be GNU utilities,
|
||||
`--with-gnu-as' and `--with-gnu-ld' need not be used; these flags will
|
||||
be auto-detected. One drawback of this option is that it won't allow
|
||||
you to override the search path for assembler and linker with
|
||||
command-line options -B/path/ if the specified filenames exist.
|
||||
_________________________________________________________________
|
||||
|
||||
cpp: Usage:... Error
|
||||
|
||||
If you get an error like this when building GCC (particularly when
|
||||
building __mulsi3), then you likely have a problem with your
|
||||
environment variables.
|
||||
cpp: Usage: /usr/lib/gcc-lib/i586-unknown-linux-gnulibc1/2.7.2.3/cpp
|
||||
[switches] input output
|
||||
|
||||
First look for an explicit '.' in either LIBRARY_PATH or
|
||||
GCC_EXEC_PREFIX from your environment. If you do not find an explicit
|
||||
'.', look for an empty pathname in those variables. Note that ':' at
|
||||
either the start or end of these variables is an implicit '.' and will
|
||||
cause problems.
|
||||
|
||||
Also note '::' in these paths will also cause similar problems.
|
||||
_________________________________________________________________
|
||||
|
||||
Optimizing the compiler itself
|
||||
|
||||
If you want to test a particular optimization option, it's useful to
|
||||
try bootstrapping the compiler with that option turned on. For
|
||||
example, to test the -fssa option, you could bootstrap like this:
|
||||
make BOOT_CFLAGS="-O2 -fssa" bootstrap
|
||||
_________________________________________________________________
|
||||
|
||||
Testsuite problems
|
||||
|
||||
Unable to run the testsuite
|
||||
|
||||
If you get a message about unable to find "standard.exp" when trying
|
||||
to run the GCC testsuites, then your dejagnu is too old to run the GCC
|
||||
tests. You will need to get a newer version of dejagnu from
|
||||
[47]http://www.gnu.org/software/dejagnu/dejagnu.html.
|
||||
_________________________________________________________________
|
||||
|
||||
How do I pass flags like -fnew-abi to the testsuite?
|
||||
|
||||
If you invoke runtest directly, you can use the --tool_opts option,
|
||||
e.g:
|
||||
runtest --tool_opts "-fnew-abi -fno-honor-std" <other options>
|
||||
|
||||
Or, if you use make check you can use the make variable RUNTESTFLAGS,
|
||||
e.g:
|
||||
make RUNTESTFLAGS="--tool_opts '-fnew-abi -fno-honor-std'" check-g++
|
||||
_________________________________________________________________
|
||||
|
||||
How can I run the test suite with multiple options?
|
||||
|
||||
If you invoke runtest directly, you can use the --target_board option,
|
||||
e.g:
|
||||
runtest --target_board "unix{-fPIC,-fpic,}" <other options>
|
||||
|
||||
Or, if you use make check you can use the make variable RUNTESTFLAGS,
|
||||
e.g:
|
||||
make RUNTESTFLAGS="--target_board 'unix{-fPIC,-fpic,}'" check-gcc
|
||||
|
||||
Either of these examples will run the tests three times. Once with
|
||||
-fPIC, once with -fpic, and once with no additional flags.
|
||||
|
||||
This technique is particularly useful on multilibbed targets.
|
||||

|
||||
|
||||
Older versions of GCC and EGCS
|
||||
|
||||
Is there a stringstream / sstream for GCC 2.95.2?
|
||||
|
||||
Yes, it's at:
|
||||
[48]http://gcc.gnu.org/ml/libstdc++/2000-q2/msg00700/sstream.
|
||||

|
||||
|
||||
Miscellaneous
|
||||
|
||||
Virtual memory exhausted error
|
||||
|
||||
This error means your system ran out of memory; this can happen for
|
||||
large files, particularly when optimizing. If you're getting this
|
||||
error you should consider trying to simplify your files or reducing
|
||||
the optimization level.
|
||||
|
||||
Note that using -pedantic or -Wreturn-type can cause an explosion in
|
||||
the amount of memory needed for template-heavy C++ code, such as code
|
||||
that uses STL. Also note that -Wall includes -Wreturn-type, so if you
|
||||
use -Wall you will need to specify -Wno-return-type to turn it off.
|
||||

|
||||
|
||||
Friend Templates
|
||||
|
||||
In order to make a specialization of a template function a friend of a
|
||||
(possibly template) class, you must explicitly state that the friend
|
||||
function is a template, by appending angle brackets to its name, and
|
||||
this template function must have been declared already. Here's an
|
||||
example:
|
||||
template <typename T> class foo {
|
||||
friend void bar(foo<T>);
|
||||
}
|
||||
|
||||
The above declaration declares a non-template function named bar, so
|
||||
it must be explicitly defined for each specialization of foo. A
|
||||
template definition of bar won't do, because it is unrelated with the
|
||||
non-template declaration above. So you'd have to end up writing:
|
||||
void bar(foo<int>) { /* ... */ }
|
||||
void bar(foo<void>) { /* ... */ }
|
||||
|
||||
If you meant bar to be a template function, you should have
|
||||
forward-declared it as follows. Note that, since the template function
|
||||
declaration refers to the template class, the template class must be
|
||||
forward-declared too:
|
||||
template <typename T>
|
||||
class foo;
|
||||
|
||||
template <typename T>
|
||||
void bar(foo<T>);
|
||||
|
||||
template <typename T>
|
||||
class foo {
|
||||
friend void bar<>(foo<T>);
|
||||
};
|
||||
|
||||
template <typename T>
|
||||
void bar(foo<T>) { /* ... */ }
|
||||
|
||||
In this case, the template argument list could be left empty, because
|
||||
it can be implicitly deduced from the function arguments, but the
|
||||
angle brackets must be present, otherwise the declaration will be
|
||||
taken as a non-template function. Furthermore, in some cases, you may
|
||||
have to explicitly specify the template arguments, to remove
|
||||
ambiguity.
|
||||
|
||||
An error in the last public comment draft of the ANSI/ISO C++ Standard
|
||||
and the fact that previous releases of GCC would accept such friend
|
||||
declarations as template declarations has led people to believe that
|
||||
the forward declaration was not necessary, but, according to the final
|
||||
version of the Standard, it is.

|
||||
|
||||
dynamic_cast, throw, typeid don't work with shared libraries
|
||||
|
||||
The new C++ ABI in the GCC 3.0 series uses address comparisons, rather
|
||||
than string compares, to determine type equality. This leads to better
|
||||
performance. Like other objects that have to be present in the final
|
||||
executable, these std::typeinfo_t objects have what is called vague
|
||||
linkage because they are not tightly bound to any one particular
|
||||
translation unit (object file). The compiler has to emit them in any
|
||||
translation unit that requires their presence, and then rely on the
|
||||
linking and loading process to make sure that only one of them is
|
||||
active in the final executable. With static linking all of these
|
||||
symbols are resolved at link time, but with dynamic linking, further
|
||||
resolution occurs at load time. You have to ensure that objects within
|
||||
a shared library are resolved against objects in the executable and
|
||||
other shared libraries.
|
||||
* For a program which is linked against a shared library, no
|
||||
additional precautions need taking.
|
||||
* You cannot create a shared library with the "-Bsymbolic" option,
|
||||
as that prevents the resolution described above.
|
||||
* If you use dlopen to explicitly load code from a shared library,
|
||||
you must do several things. First, export global symbols from the
|
||||
executable by linking it with the "-E" flag (you will have to
|
||||
specify this as "-Wl,-E" if you are invoking the linker in the
|
||||
usual manner from the compiler driver, g++). You must also make
|
||||
the external symbols in the loaded library available for
|
||||
subsequent libraries by providing the RTLD_GLOBAL flag to dlopen.
|
||||
The symbol resolution can be immediate or lazy.
|
||||
|
||||
Template instantiations are another, user visible, case of objects
|
||||
with vague linkage, which needs similar resolution. If you do not take
|
||||
the above precautions, you may discover that a template instantiation
|
||||
with the same argument list, but instantiated in multiple translation
|
||||
units, has several addresses, depending in which translation unit the
|
||||
address is taken. (This is not an exhaustive list of the kind of
|
||||
objects which have vague linkage and are expected to be resolved
|
||||
during linking & loading.)
|
||||
|
||||
If you are worried about different objects with the same name
|
||||
colliding during the linking or loading process, then you should use
|
||||
namespaces to disambiguate them. Giving distinct objects with global
|
||||
linkage the same name is a violation of the One Definition Rule (ODR)
|
||||
[basic.def.odr].
|
||||
|
||||
For more details about the way that GCC implements these and other C++
|
||||
features, please read the [49]ABI specification. Note the
|
||||
std::typeinfo_t objects which must be resolved all begin with "_ZTS".
|
||||
Refer to ld's documentation for a description of the "-E" &
|
||||
"-Bsymbolic" flags.
|
||||

|
||||
|
||||
Why do I need autoconf, bison, xgettext, automake, etc?
|
||||
|
||||
If you're using diffs up dated from one snapshot to the next, or if
|
||||
you're using the CVS repository, you may need several additional
|
||||
programs to build GCC.
|
||||
|
||||
These include, but are not necessarily limited to autoconf, automake,
|
||||
bison, and xgettext.
|
||||
|
||||
This is necessary because neither diff nor cvs keep timestamps
|
||||
correct. This causes problems for generated files as "make" may think
|
||||
those generated files are out of date and try to regenerate them.
|
||||
|
||||
An easy way to work around this problem is to use the gcc_update
|
||||
script in the contrib subdirectory of GCC, which handles this
|
||||
transparently without requiring installation of any additional tools.
|
||||
(Note: Up to and including GCC 2.95 this script was called egcs_update
|
||||
.)
|
||||
|
||||
When building from diffs or CVS or if you modified some sources, you
|
||||
may also need to obtain development versions of some GNU tools, as the
|
||||
production versions do not necessarily handle all features needed to
|
||||
rebuild GCC.
|
||||
|
||||
In general, the current versions of these tools from
|
||||
[50]ftp://ftp.gnu.org/gnu/ will work. At present, Autoconf 2.50 is not
|
||||
supported, and you will need to use Autoconf 2.13; work is in progress
|
||||
to fix this problem. Also look at
|
||||
[51]ftp://gcc.gnu.org/pub/gcc/infrastructure/ for any special versions
|
||||
of packages.
|
||||
_________________________________________________________________
|
||||
|
||||
Why can't I build a shared library?
|
||||
|
||||
When building a shared library you may get an error message from the
|
||||
linker like `assert pure-text failed:' or `DP relative code in file'.
|
||||
|
||||
This kind of error occurs when you've failed to provide proper flags
|
||||
to gcc when linking the shared library.
|
||||
|
||||
You can get this error even if all the .o files for the shared library
|
||||
were compiled with the proper PIC option. When building a shared
|
||||
library, gcc will compile additional code to be included in the
|
||||
library. That additional code must also be compiled with the proper
|
||||
PIC option.
|
||||
|
||||
Adding the proper PIC option (-fpic or -fPIC) to the link line which
|
||||
creates the shared library will fix this problem on targets that
|
||||
support PIC in this manner. For example:
|
||||
gcc -c -fPIC myfile.c
|
||||
gcc -shared -o libmyfile.so -fPIC myfile.o
|
||||

|
||||
|
||||
How to work around too long C++ symbol names (-fsquangle)
|
||||
|
||||
This question does not apply to GCC 3.0 or later versions, which have
|
||||
a new C++ ABI with much shorter mangled names.
|
||||
|
||||
If the standard assembler of your platform can't cope with the large
|
||||
symbol names that the default g++ name mangling mechanism produces,
|
||||
your best bet is to use GNU as, from the GNU binutils package.
|
||||
|
||||
Unfortunately, GNU as does not support all platforms supported by GCC,
|
||||
so you may have to use an experimental work-around: the -fsquangle
|
||||
option, that enables compression of symbol names.
|
||||
|
||||
Note that this option is still under development, and subject to
|
||||
change. Since it modifies the name mangling mechanism, you'll need to
|
||||
build libstdc++ and any other C++ libraries with this option enabled.
|
||||
Furthermore, if this option changes its behavior in the future, you'll
|
||||
have to rebuild them all again. :-(
|
||||
|
||||
This option can be enabled by default by initializing
|
||||
`flag_do_squangling' with `1' in `gcc/cp/decl2.c' (it is not
|
||||
initialized by default), then rebuilding GCC and any C++ libraries.
|
||||
_________________________________________________________________
|
||||
|
||||
When building C++, the linker says my constructors, destructors or virtual
|
||||
tables are undefined, but I defined them
|
||||
|
||||
The ISO C++ Standard specifies that all virtual methods of a class
|
||||
that are not pure-virtual must be defined, but does not require any
|
||||
diagnostic for violations of this rule [class.virtual]/8. Based on
|
||||
this assumption, GCC will only emit the implicitly defined
|
||||
constructors, the assignment operator, the destructor and the virtual
|
||||
table of a class in the translation unit that defines its first such
|
||||
non-inline method.
|
||||
|
||||
Therefore, if you fail to define this particular method, the linker
|
||||
may complain about the lack of definitions for apparently unrelated
|
||||
symbols. Unfortunately, in order to improve this error message, it
|
||||
might be necessary to change the linker, and this can't always be
|
||||
done.
|
||||
|
||||
The solution is to ensure that all virtual methods that are not pure
|
||||
are defined. Note that a destructor must be defined even if it is
|
||||
declared pure-virtual [class.dtor]/7.
|
||||
_________________________________________________________________
|
||||
|
||||
Will GCC someday include an incremental linker?
|
||||
|
||||
Incremental linking is part of the linker, not the compiler. As such,
|
||||
GCC doesn't have anything to do with incremental linking. Depending on
|
||||
what platform you use, it may be possible to tell GCC to use the
|
||||
platform's native linker (e.g., Solaris' ild(1)).

Submitting Bug Reports using GNATS
|
||||
|
||||
gnatsweb and gccbug
|
||||
|
||||
GNATS, the GNU bug tracking system, is used to track GCC bug reports.
|
||||
Before submitting a bug report, please read the [1]general
|
||||
instructions.
|
||||
|
||||
The preferred way to submit a bug report is by means of the
|
||||
[2]gnatsweb interface. Make sure you include an e-mail address, so we
|
||||
can inform you when the status of your report changes.
|
||||
|
||||
Another way is to use the gccbug program that is automatically
|
||||
installed with current versions of GCC, which submits the bug report
|
||||
by e-mail.
|
||||
|
||||
Both techniques use the same GNATS bug database.
|
||||
|
||||
Filling out a report
|
||||
|
||||
The bug report form provides a number of fields; you'll need to
|
||||
fill-out most of those (as indicated below) to provide a complete
|
||||
report. The fields have the following purpose:
|
||||
|
||||
Originator
|
||||
Your name.
|

<h1><a name="report">Reporting Bugs</a></h1>
|
||||
|
||||
<p>Our preferred way of receiving bugs is via the
|
||||
<a href="gnats.html">GCC GNATS bug reporting system</a>.</p>
|
||||
|
||||
<p>Before you report a bug, please check the
|
||||
<a href="#known">list of well-known bugs</a> and, <strong>if possible
|
||||
in any way, try a current development snapshot</strong>.
|
||||
If you want to report a bug with versions of GCC before 3.1 we strongly
|
||||
recommend upgrading to the current release first.</p>
|
||||
|
||||
<p>Before reporting that GCC compiles your code incorrectly, please
|
||||
compile it with <code>gcc -Wall</code> and see whether this shows
|
||||
anything wrong with your code that could be the cause instead of a bug
|
||||
in GCC.</p>
|
||||
|
||||
<h2>Summarized bug reporting instructions</h2>
|
||||
|
||||
<p>After this summary, you'll find detailed bug reporting
|
||||
instructions, that explain how to obtain some of the information
|
||||
requested in this summary.</p>
|
||||
|
||||
<h3><a name="need">What we need</a></h3>
|
||||
|
||||
Please include in your bug report all of the following items, the first
|
||||
three of which can be obtained from the output of <code>gcc -v</code>:
|
||||
|
||||
<ul>
|
||||
<li>the exact version of GCC;</li>
|
||||
<li>the system type;</li>
|
||||
<li>the options given when GCC was configured/built;</li>
|
||||
<li>the complete command line that triggers the bug;</li>
|
||||
<li>the compiler output (error messages, warnings, etc.); and</li>
|
||||
<li>the <em>preprocessed</em> file (<code>*.i*</code>) that triggers the
|
||||
bug, generated by adding <code>-save-temps</code> to the complete
|
||||
compilation command, or, in the case of a bug report for the GNAT front end,
|
||||
a complete set of source files (see below).</li>
|
||||
</ul>
|
||||
|
||||
<h3><a name="dontwant">What we do <strong>not</strong> want</a></h3>
|
||||
|
||||
<ul>
|
||||
<li>A source file that <code>#include</code>s header files that are left
|
||||
out of the bug report (see above)</li>
|
||||
|
||||
<li>That source file and a collection of header files.</li>
|
||||
|
||||
<li>An attached archive (tar, zip, shar, whatever) containing all
|
||||
(or some :-) of the above.</li>
|
||||
|
||||
<li>A code snippet that won't cause the compiler to produce the
|
||||
exact output mentioned in the bug report (e.g., a snippet with just
|
||||
a few lines around the one that <b>apparently</b> triggers the bug,
|
||||
with some pieces replaced with ellipses or comments for extra
|
||||
obfuscation :-)</li>
|
||||
|
||||
<li>The location (URL) of the package that failed to build (we won't
|
||||
download it, anyway, since you've already given us what we need to
|
||||
duplicate the bug, haven't you? :-)</li>
|
||||
|
||||
<li>An error that occurs only some of the times a certain file is
|
||||
compiled, such that retrying a sufficient number of times results in
|
||||
a successful compilation; this is a symptom of a hardware problem,
|
||||
not of a compiler bug (sorry)</li>
|
||||
|
||||
<li>E-mail messages that complement previous, incomplete bug
|
||||
reports. Post a new, self-contained, full bug report instead, if
|
||||
possible as a follow-up to the original bug report</li>
|
||||
|
||||
<li>Assembly files (<code>*.s</code>) produced by the compiler, or any
|
||||
binary files, such as object files, executables or core files</li>
|
||||
|
||||
<li>Duplicate bug reports, or reports of bugs already fixed in the
|
||||
development tree, especially those that have already been reported
|
||||
as fixed last week :-)</li>
|
||||
|
||||
<li>Bugs in the assembler, the linker or the C library. These are
|
||||
separate projects, with separate mailing lists and different bug
|
||||
reporting procedures</li>
|
||||
|
||||
<li>Bugs in releases or snapshots of GCC not issued by the GNU
|
||||
Project. Report them to whoever provided you with the release</li>
|
||||
|
||||
<li>Questions about the correctness or the expected behavior of
|
||||
certain constructs that are not GCC extensions. Ask them in forums
|
||||
dedicated to the discussion of the programming language</li>
|
||||
</ul>
|
||||
|
||||
<h3><a name="where">Where to post it</a></h3>
|
||||
|
||||
<p>Please submit your bug report directly to the
|
||||
<a href="gnats.html">GCC GNATS bug database</a>.
|
||||
Only if this is not possible, mail all information to
|
||||
<a href="mailto:bug-gcc@gnu.org">bug-gcc@gnu.org</a> or
|
||||
<a href="mailto:gcc-bugs@gcc.gnu.org">gcc-bugs@gcc.gnu.org</a>.</p>
|
||||
|
||||
<p>The GCC lists have message size limits (200 kbytes) and bug reports
|
||||
over those limits will currently be bounced. If your bug is larger
|
||||
than that, please post it using the <a href="gnats.html">GCC GNATS bug
|
||||
database</a>.</p>
|
||||
|
||||
<h2><a name="detailed">Detailed bug reporting instructions</a></h2>
|
||||
|
||||
<p>Please refer to the <a href="#gnat">next section</a> when reporting
|
||||
bugs in GNAT, the Ada compiler.</p>
|
||||
|
||||
<p>In general, all the information we need can be obtained by
|
||||
collecting the command line below, as well as its output and the
|
||||
preprocessed file it generates.</p>
|
||||
|
||||
<blockquote><code>gcc -v -save-temps <i>all-your-options
|
||||
source-file</i></code></blockquote>
|
||||
|
||||
<p>Typically the preprocessed file (extension <code>.i</code> for C or
|
||||
<code>.ii</code> for C++) will be large, so please compress the
|
||||
resulting file with one of the popular compression programs such as
|
||||
bzip2, gzip, zip or compress (in
|
||||
decreasing order of preference). Use maximum compression
|
||||
(<code>-9</code>) if available. Please include the compressed
|
||||
preprocessor output in your bug report, even if the source code is
|
||||
freely available elsewhere; it makes the job of our volunteer testers
|
||||
much easier.</p>
|
||||
|
||||
<p>The <b>only</b> excuses to not send us the preprocessed sources are
|
||||
(i) if you've found a bug in the preprocessor, or (ii) if you've
|
||||
reduced the testcase to a small file that doesn't include any
|
||||
other file. If you can't post the preprocessed sources because
|
||||
they're proprietary code, then try to create a small file that
|
||||
triggers the same problem.</p>
|
||||
|
||||
<p>Since we're supposed to be able to re-create the assembly output
|
||||
(extension <code>.s</code>), you usually should not include
|
||||
it in the bug report, although you may want to post parts of it to
|
||||
point out assembly code you consider to be wrong.</p>
|
||||
|
||||
<p>Whether to use MIME attachments or <code>uuencode</code> is up to
|
||||
you. In any case, make sure the compiler command line, version and
|
||||
error output are in plain text, so that we don't have to decode the
|
||||
bug report in order to tell who should take care of it. A meaningful
|
||||
subject indicating language and platform also helps.</p>
|
||||
|
||||
<p>Please avoid posting an archive (.tar, .shar or .zip); we generally
|
||||
need just a single file to reproduce the bug (the .i/.ii preprocessed
|
||||
file), and, by storing it in an archive, you're just making our
|
||||
volunteers' jobs harder. Only when your bug report requires multiple
|
||||
source files to be reproduced should you use an archive. In any case,
|
||||
make sure the compiler version, error message, etc, are included in
|
||||
the body of your bug report as plain text, even if needlessly
|
||||
duplicated as part of an archive.</p>
|
||||
|
||||
<p>If you fail to supply enough information for a bug report to be
|
||||
reproduced, someone will probably ask you to post additional
|
||||
information (or just ignore your bug report, if they're in a bad day,
|
||||
so try to get it right on the first posting :-). In this case, please
|
||||
post the additional information to the bug reporting mailing list, not
|
||||

<h2><a name="gnat">Detailed bug reporting instructions for GNAT</a></h2>
|
||||
|
||||
<p>See the <a href="#detailed">previous section</a> for bug reporting
|
||||
instructions for GCC language implementations other than Ada.</p>
|
||||
|
||||
<p>Bug reports have to contain at least the following information in
|
||||
order to be useful:</p>
|
||||
|
||||
<ul>
|
||||
<li>the exact version of GCC, as shown by "<code>gcc -v</code>";</li>
|
||||
<li>the system type;</li>
|
||||
<li>the options when GCC was configured/built;</li>
|
||||
<li>the exact command line passed to the <code>gcc</code> program
|
||||
triggering the bug
|
||||
(not just the flags passed to <code>gnatmake</code>, but
|
||||
<code>gnatmake</code> prints the parameters it passed to <code>gcc</code>)</li>
|
||||
<li>a collection of source files for reproducing the bug,
|
||||
preferably a minimal set (see below);</li>
|
||||
<li>a description of the expected behavior;</li>
|
||||
<li>a description of actual behavior.</li>
|
||||
</ul>
|
||||
|
||||
<p>If your code depends on additional source files (usually package
|
||||
specifications), submit the source code for these compilation units in
|
||||
a single file that is acceptable input to <code>gnatchop</code>,
|
||||
i.e. contains no non-Ada text. If the compilation terminated
|
||||
normally, you can usually obtain a list of dependencies using the
|
||||
"<code>gnatls -d <i>main_unit</i></code>" command, where
|
||||
<code><i>main_unit</i></code> is the file name of the main compilation
|
||||
unit (which is also passed to <code>gcc</code>).</p>
|
||||
|
||||
<p>If you report a bug which causes the compiler to print a bug box,
|
||||
include that bug box in your report, and do not forget to send all the
|
||||
source files listed after the bug box along with your report.</p>
|
||||
|
||||
<p>If you use <code>gnatprep</code>, be sure to send in preprocessed
|
||||
sources (unless you have to report a bug in <code>gnatprep</code>).</p>
|
||||
|
||||
<p>When you have checked that your report meets these criteria, please
|
||||
submit it accoding to our <a href="#where">generic instructions</a>.
|
||||
(If you use a mailing list for reporting, please include an
|
||||
"<code>[Ada]</code>" tag in the subject.)</p>

<h2><a name="c">C</a></h2>
|
||||
|
||||
<p>The following are not bugs in the C compiler, but are reported
|
||||
often enough to warrant a mention here.</p>
|
||||
|
||||
<dl>
|
||||
<dt>Cannot initialize a static variable with <code>stdin</code>.</dt>
|
||||
<dd><p>This has nothing to do with GCC, but people ask us about it a
|
||||
lot. Code like this:</p>
|
||||
|
||||
<blockquote><pre>
|
||||
#include <stdio.h>
|
||||
|
||||
FILE *yyin = stdin;
|
||||
</pre></blockquote>
|
||||
|
||||
<p>will not compile with GNU libc (GNU/Linux libc6), because
|
||||
<code>stdin</code> is not a constant. This was done deliberately, to make
|
||||
it easier to maintain binary compatibility when the type <code>FILE</code>
|
||||
needs to be changed. It is surprising for people used to traditional Unix
|
||||
C libraries, but it is permitted by the C standard.</p>
|
||||
|
||||
<p>This construct commonly occurs in code generated by old versions of
|
||||
lex or yacc. We suggest you try regenerating the parser with a
|
||||
current version of flex or bison, respectively. In your own code, the
|
||||
appropriate fix is to move the initialization to the beginning of
|
||||
main.</p>
|
||||
|
||||
<p>There is a common misconception that the GCC developers are
|
||||
responsible for GNU libc. These are in fact two entirely separate
|
||||
projects; please check the
|
||||
<a href="http://www.gnu.org/software/glibc/">GNU libc web pages</a>
|
||||
for details.
|
||||
</p></dd>
|
||||
|
||||
<dt>Cannot use preprocessor directive in macro arguments.</dt>
|
||||
<dd><p>Let me guess... you wrote code that looks something like this:</p>
|
||||
<blockquote><pre>
|
||||
memcpy(dest, src,
|
||||
#ifdef PLATFORM1
|
||||
12
|
||||
#else
|
||||
24
|
||||
#endif
|
||||
);
|
||||
</pre></blockquote>
|
||||
<p>and you got a whole pile of error messages:</p>
|
||||
<blockquote><code>
|
||||
|
||||
test.c:11: warning: preprocessing directive not recognized within
|
||||
macro arg<br />
|
||||

||||

|
||||
test.c:10: undefined or invalid # directive<br />
|
||||
test.c:11: parse error before `#'<br />
|
||||
</code></blockquote>
|
||||
|
||||
<p><strong>Update:</strong> As of GCC 3.2 this kind of construct is
|
||||
always accepted and CPP will probably do what you expect, but see the
|
||||
manual for detailed semantics.</p>
|
||||
|
||||
<p>However, versions of GCC prior to 3.2 did not allow you to put
|
||||
<code>#ifdef</code> (or any other directive) inside the arguments of a
|
||||
macro. Your C library's <code><string.h></code> happens to
|
||||
define <code>memcpy</code> as a macro - this is perfectly legitimate.
|
||||
The code therefore would not compile.</p>
|
||||
|
||||
<p>This kind of code is not portable. It is "undefined behavior"
|
||||
according to the C standard; that means different compilers will do
|
||||
different things with it. It is always possible to rewrite code which
|
||||
uses conditionals inside macros so that it doesn't. You could write
|
||||
the above example</p>
|
||||
<blockquote><pre>
|
||||
#ifdef PLATFORM1
|
||||
memcpy(dest, src, 12);
|
||||
#else
|
||||
memcpy(dest, src, 24);
|
||||
#endif
|
||||
</pre></blockquote>
|
||||
<p>This is a bit more typing, but I personally think it's better style
|
||||
in addition to being more portable.</p>
|
||||
|
||||
<p>In recent versions of glibc, <code>printf</code> is among the
|
||||
functions which are implemented as macros.</p></dd>

<h2><a name="cplusplus">C++</a></h2>
|
||||
|
||||
<p>This is the list of bugs (and non-bugs) in g++ (aka GNU C++) that
|
||||
are reported very often, but not yet fixed. While it is certainly
|
||||
better to fix bugs instead of documenting them, this document might
|
||||
save people the effort of writing a bug report when the bug is already
|
||||
well-known. <a href="#report">How to report bugs</a> tells you how to
|
||||
report a bug.</p>
|
||||
|
||||
<p>There are many reasons why reported bugs don't get fixed. It might
|
||||
be difficult to fix, or fixing it might break compatibility. Often,
|
||||
reports get a low priority when there is a simple work-around. In
|
||||
particular, bugs caused by invalid C++ code have a simple work-around,
|
||||
<em>fix the code</em>. Now that there is an agreed ISO/ANSI standard
|
||||
for C++, the compiler has a definitive document to adhere to. Earlier
|
||||
versions might have accepted source code that is <em>no longer</em>
|
||||
C++. This means that code which might have `worked' in a previous
|
||||
version, is now rejected. You should update your code to be C++.</p>
|

<p>You should try to use the latest stable release of the GNU C++

compiler.</p>

<h3><a name="updating">Common problems updating from G++ 2.95 to G++
|
||||
3.0</a></h3>
|
||||
|
||||
<p>G++ 3.0 conforms much closer to the ISO C++ standard (available at
|
||||
<a href="http://www.ncits.org/cplusplus.htm">http://www.ncits.org/cplusplus.htm</a>).</p>
|
||||
|
||||
<p>We have also implemented some of the core and library defect reports
|
||||
(available at
|
||||
<a href="http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html">http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html</a>

|

http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/lwg-defects.html</a>
|
||||
respectively).</p>
|
||||
|
||||
<ul>
|
||||
|
||||
<li>The ABI has changed. This means that both class layout and name
|
||||
mangling is different. You <em>must</em> recompile all c++ libraries (if
|
||||
you don't you will get link errors).</li>
|
||||
|
||||
<li>The standard library is much more conformant, and uses the
|
||||
<code>std::</code> namespace.</li>
|
||||
|
||||
<li><code>std::</code> is now a real namespace, not an alias for
|
||||
<code>::</code>.</li>
|
||||
|
||||
<li>The standard header files for the c library don't end with
|
||||
<code>.h</code>, but begin with <code>c</code> (i.e.
|
||||
<code><cstdlib></code> rather than <code><stdlib.h></code>).
|
||||
The <code>.h</code> names are still available, but are deprecated.</li>
|
||||
|
||||
<li><code><strstream></code> is deprecated, use
|
||||
<code><sstream></code> instead.</li>
|
||||
|
||||
<li><code>streambuf::seekoff</code> &
|
||||
<code>streambuf::seekpos</code> are private, instead use
|
||||
<code>streambuf::pubseekoff</code> &
|
||||
<code>streambuf::pubseekpos</code> respectively.</li>
|
||||
|
||||
<li>If <code>std::operator << (std::ostream &, long long)</code>
|
||||
doesn't exist, you need to recompile libstdc++ with
|
||||
<code>--enable-long-long</code>.</li>
|
||||
|
||||
</ul>
|
||||
|
||||
This means you may get lots of errors about things like
|
||||
<code>strcmp</code> not being found. You've most likely forgotton to
|
||||
tell the compiler to look in the <code>std::</code> namespace. There are
|
||||
several ways to do this,
|
||||
|
||||
<ul>
|
||||
|
||||
<li>Say, <code>std::strcmp</code> at the call. This is the most explicit
|
||||
way of saying what you mean.</li>
|
||||
|
||||
<li>Say, <code>using std::strcmp;</code> somewhere before the call. You
|
||||
will need to do this for each function or type you wish to use from the
|
||||
standard library.</li>
|
||||
|
||||
<li>Say, <code>using namespace std;</code> somewhere before the call.
|
||||
This is the quick-but-dirty fix. This brings the <em>whole</em> of the
|
||||
<code>std::</code> namespace into scope. <em>Never</em> do this in a
|
||||
header file, as you will be forcing users of your header file to do the
|
||||
same.</li>

<h3><a name="abi">ABI bugs</a></h3>
|

<p>3.0 had a new ABI, which affected class layout, function mangling and

calling conventions. We had intended it to be complete, unfortunately
|
||||
some issues came to light, too late to fix in the 3.0 series.
|

The ABI should not change in dot releases, so we addressed most issues

in GCC 3.1.

class.</p></dd>
|

<dt>Classes in exception specifiers must be complete types.</dt>
|
||||
<dd><p>[15.4]/1 tells you that you cannot have an incomplete type, or

an exception specification.</p></dd>
|
||||
|
||||
<dt>G++ emits two copies of constructors and destructors.</dt>
|
||||
|
||||
<dd><p>In general there are <em>three</em> types of constructors (and
|

destructors).</p>
|
||||
<ol>
|

<li>The complete object constructor/destructor.</li>
|
||||
<li>The base object constructor/destructor.</li>
|

<li>The allocating destructor/deallocating destructor.</li>
|
||||
</ol>
|
||||
<p>The first two are different, when virtual base classes are involved.

In some cases we can do better, and this is logged in GNATS.</p></dd>
|

|

<dt>Exceptions don't work in multithreaded applications.</dt>
|
||||
|
||||
<dd><p>You need to rebuild g++ and libstdc++ with
|
||||
<code>--enable-threads</code>. Remember, c++ exceptions are not like
|
||||
hardware interrupts. You cannot throw an exception in one thread and
|
||||
catch it in another. You cannot throw an exception from a signal
|
||||
handler, and catch it in the main thread.</p></dd>
|
||||
|
||||
<dt>Global destructors are not run in the correct order.</dt>
|
||||
|
||||
<dd><p>Global destructors should be run in the reverse order of their
|
||||
constructors <em>completing</em>. In most cases this is the same as
|
||||
the reverse order of constructors <em>starting</em>, but sometimes it

||||
is different, and that is important. You need to compile and link your
|
||||
programs with <code>--use-cxa-atexit</code>. We have not turned this
|
||||
switch on by default, as it requires a <code>cxa</code> aware runtime
|
||||
library (<code>libc</code>, <code>glibc</code>, or
|
||||
equivalent).</p></dd>
|
||||
|
||||
<dt>Problems with floating point computations.</dt>
|
||||
<dd><p>In a number of cases, GCC appears to perform floating point
|
||||
computations incorrectly. For example, the program</p>
|
||||
<blockquote><code>
|
||||
#include <iostream><br />
|
||||
<br />
|
||||
int main() {<br />
|

<br />
|

double min = 0.0;<br />
|

double max = 0.5;<br />
|
||||
double width = 0.01;<br />
|
||||
std::cout << (int)(((max - min) / width) - 1) <<
|
||||
std::endl;<br />
|
||||
<br />
|
||||
}<br />
|
||||
</code></blockquote>
|
||||
<p>might print 50 on some systems and optimization levels, and 51 on
|
||||
others.</p>
|
||||
|
||||
<p>The is the result of <em>rounding</em>: The computer cannot
|
||||
represent all real numbers exactly, so it has to use
|
||||
approximations. When computing with approximation, the computer needs
|
||||
to round to the nearest representable number.</p>
|
||||
|
||||
<p>This is not a bug in the compiler, but an inherent limitation of
|
||||
the float and double types. Please study
|
||||

for more information.</p></dd>
|
||||
|
||||
<dt>Templates, scoping, and digraphs.</dt>
|
||||
|
||||
<dd><p>If you have a class in global namespace, say named
|
||||
<code>X</code>, and want to give it as a template argument to some
|
||||
other class, say <code>std::vector</code>, then this here fails with a
|
||||
parser error: <code>std::vector<::X></code>.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
The reason is that the standard mandates that the sequence
|
||||
<code><:</code> is treated as if it were the token
|
||||
<code>[</code>, and the parser then reports a parse error before the
|
||||
character <code>:</code> (by which it means the second
|
||||
colon). There are several such combinations of characters, and
|
||||
they are called <em>digraphs</em>.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
The simplest way to avoid this is to write <code>std::vector<
|
||||
::X></code>, i.e. place a space between the opening angle bracket
|
||||
and the scope operator.

<h3><a name="parsing">Parse errors for "simple" code</a></h3>
|
||||
|
||||
Up to and including GCC 3.0, the compiler will give "parse error" for
|
||||
seemingly simple code, such as
|
||||
|
||||
<pre>
|
||||
struct A{
|
||||
A();
|
||||
A(int);
|
||||
void func();
|
||||
};
|
||||
|
||||
struct B{
|
||||
B(A);
|
||||
B(A,A);
|
||||
void func();
|
||||
};
|
||||
|
||||
void foo(){
|
||||
B b(A(),A(1)); //Variable b, initialized with two temporaries
|
||||
B(A(2)).func(); //B temporary, initialized with A temporary
|
||||
}
|
||||
</pre>
|
||||
The problem is that GCC starts to parse the declaration of
|
||||
<code>b</code> as a function <code>b</code> returning <code>B</code>,
|
||||
taking a function returning <code>A</code> as an argument. When it
|
||||
sees the 1, it is too late. The work-around in these cases is to add
|
||||
additional parentheses around the expressions that are mistaken as
|
||||
declarations:
|
||||
<pre>
|
||||
(B(A(2))).func();
|
||||
</pre>
|
||||
Sometimes, even that is not enough; to show the compiler that this
|
||||
should be really an expression, a comma operator with a dummy argument
|
||||
can be used:
|
||||
<pre>
|
||||
B b((0,A()),A(1));
|
||||
</pre>
|
||||
<p>
|
||||
Another example is the parse error for the <code>return</code>
|
||||
statement in</p>

|

<p>The problem is that the compiler interprets <code>A()</code> as a
|
||||
function (taking no arguments, returning <code>A</code>), and
|
||||
<code>(A()</code>) as a cast - with a missing expression, hence the
|
||||
parse error. The work-around is to omit the parentheses:</p>
|
||||
<pre>
|
||||
if (b)
|
||||
return A();
|
||||
</pre>
|
||||
<p>This problem occurs in a number of variants; in <code>throw</code>
|
||||
statements, people also frequently put the object in parentheses. The
|
||||
exact error also somewhat varies with the compiler version. The
|
||||
work-arounds proposed do not change the semantics of the program at
|
||||
all; they make them perhaps less readable.</p>
|
||||
|
||||
<h3><a name="-O3">Optimization at <code>-O3</code> takes a
|
||||
very long time</a></h3>
|
||||
<p>At <code>-O3</code>, all functions are candidates for inlining. The
|
||||
heuristic used has some deficiencies which show up when allowed such
|
||||
freedom. This is g++ specific, as it has an earlier inliner than
|
||||
gcc.</p>

# Configure fragment invoked in the post-target section for subdirs

# wanting multilib support.
|

#
|

# It is advisable to support a few --enable/--disable options to let the
|
||||
# user select which libraries s/he really wants.
|
||||
#
|
||||
# Subdirectories wishing to use multilib should put the following lines
|
||||
# in the "post-target" section of configure.in.
|
||||
#
|

# if [ "${srcdir}" = "." ] ; then
|
||||
# if [ "${with_target_subdir}" != "." ] ; then
|

# . ${with_multisrctop}../../config-ml.in
|

# else

# fi

||||
#
|
||||
# Things are complicated because 6 separate cases must be handled:
|
||||
# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
|
||||
#
|
||||
# srcdir=. is special. It must handle make programs that don't handle VPATH.
|
||||
# To implement this, a symlink tree is built for each library and for each
|
||||
# multilib subdir.
|
||||
#
|
||||
# The build tree is layed out as
|
||||
#
|
||||
# ./
|
||||
# newlib
|
||||
# m68020/
|
||||
# newlib
|
||||
# m68881/
|
||||
# newlib
|
||||
#
|
||||
# The nice feature about this arrangement is that inter-library references
|
||||
# in the build tree work without having to care where you are. Note that
|
||||
# inter-library references also work in the source tree because symlink trees
|
||||
# are built when srcdir=.
|
||||
#
|
||||
# Unfortunately, trying to access the libraries in the build tree requires
|
||||
# the user to manually choose which library to use as GCC won't be able to
|
||||
# find the right one. This is viewed as the lesser of two evils.
|
||||
#
|
||||
# Configure variables:
|
||||
# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
|
||||
# Set by top level Makefile.
|
||||
# ${with_multisrctop} = how many levels of multilibs there are in the source
|
||||
# tree. It exists to handle the case of configuring in the source tree:
|
||||
# ${srcdir} is not constant.
|
||||
# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
|
||||
#
|
||||
# Makefile variables:
|
||||
# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
|
||||
# (FIXME: note that this is different than ${with_multisrctop}. Check out.).
|
||||
# MULTIBUILDTOP = number of multilib levels in build tree

||||
# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)

Fri Nov 5 08:12:32 1993 D. V. Henkel-Wallace (gumby@blues.cygnus.com)

can't tell the difference. So don't allow skew.

Tue Oct 19 18:58:21 1993 Jim Kingdon (kingdon@lioth.cygnus.com)

|

different from anything else? ("gdb doesn't understand the native
|
||||
debug format" isn't a good enough answer because we might be using
|

gcc).

mh-ncr3000, mh-solaris, mh-sysv, mh-sysv4: remove INSTALL=cp line,

Thu Apr 8 11:21:52 1993 Ian Lance Taylor (ian@cygnus.com)

* mt-a29k, mt-ebmon29k, mt-os68k, mt-ose68000, mt-ose68k,

mt-vxworks68, mt-vxworks960: Removed obsolete, unused target

Mon Mar 8 15:05:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

Thu Oct 1 13:50:48 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

Mon Aug 24 14:25:35 1992 Ian Lance Taylor (ian@cygnus.com)
|

|

Tue Jul 21 02:11:01 1992 D. V. Henkel-Wallace (gumby@cygnus.com)

Thu Jul 16 17:12:09 1992 K. Richard Pixley (rich@rtl.cygnus.com)

|
||||
|
||||
Tue Jun 9 23:29:38 1992 Per Bothner (bothner@rtl.cygnus.com)
|
||||
|
||||
* Everywhere: Change RANLIB=echo>/dev/null (which confuses
|
||||
some shells - and I don't blame them) to RANLIB=true.
|
||||
* mh-solaris: Use /usr/ucb/install for INSTALL.
|

|
||||
Sun May 31 14:45:23 1992 Mark Eichin (eichin at cygnus.com)
|

Fri Apr 10 23:10:08 1992 Fred Fish (fnf@cygnus.com)

|
||||
This directory contains MPW scripts and related files that are needed to
|
||||
build Cygnus GNU tools for MPW. The scripts should be somewhere on the
|
||||
command path; our usual practice has been to have a separate directory
|
||||
for the scripts, and put the tools (byacc, flex, and sed at least) there
|
||||
also; then it's easier to drag the support bits around as a group, or to
|
||||
upgrade MPW versions. The complete package of scripts and tool binaries
|
||||
is usually available as pub/mac/buildtools.cpt.hqx on ftp.cygnus.com.
|
||||
|
||||
"tr-7to8-src" is actually the source to an MPW script that transforms
|
||||
sequences like "\Option-d" into the actual 8-bit chars that MPW needs.
|
||||
It's only the source because it can't itself include any 8-bit chars.
|
||||
It *can* be processed into a genuine "tr-7to8" by using itself:
|
||||
|
||||
tr-7to8 tr-7to8-src | sed -e 's/Src//' >new-tr-7to8
|
||||
|
||||
Use this to verify:
|
||||
|
||||
compare tr-7to8 new-tr-7to8
|
||||
|
||||
If you don't have a working tr-7to8, then you will have to manually
|
||||
replace all occurrences of "\Option-d" with real Option-d (which looks
|
||||
like a delta), then do similarly with all the other "\Option-..."
|
||||
strings, and then change "\SrcOption-d" into the string "\Option-d".

|
||||
#
|
||||
#
|
||||
# This script is used to calculate two basic properties of the branch prediction
|
||||
# heuristics - coverage and hitrate. Coverage is number of executions of a given
|
||||
# branch matched by the heuristics and hitrate is probability that once branch is
|
||||
# predicted as taken it is really taken.
|
||||
#
|
||||
# These values are useful to determine the quality of given heuristics. Hitrate
|
||||
# may be directly used in predict.c.
|
||||
#
|
||||
# Usage:
|
||||
# Step 1: Compile and profile your program. You need to use -fprofile-arcs
|
||||
# flag to get the profiles
|
||||
# Step 2: Generate log files. The information about given heuristics are
|
||||
# saved into *.life dumps. You need to pass the -df switch to the compiler as well
|
||||
# as -fbranch-probabilities to get the results of profiling noted in the dumps.
|
||||
# Ensure that there are no "Arc profiling: some edge counts were bad." warnings.
|
||||
# Step 3: Run this script to concatenate all *.life files:
|
||||
# analyze_brprob `find . -name *.life`
|
||||
# the information is collected and print once all files are parsed. This
|
||||
# may take a while.
|
||||
# Note that the script does use bc to perform long arithmetic.
|
||||
# Step 4: Read the results. Basically the following table is printed:
|
||||
# (this is just an example from a very early stage of branch prediction pass
|
||||
# development, so please don't take these numbers seriously)
|
||||
#

||||

|

#
|
||||
# The heuristic called "first match" is a heuristic used by GCC branch
|
||||
# prediction pass and it predicts 89.92% branches correctly.
|
||||
#
|
||||
# The quality of heuristics can be rated using both, coverage and hitrate
|
||||
# parameters. For example "loop branch" heuristics (predicting loopback edge
|
||||
# as taken) have both very high hitrate and coverage, so it is very useful.
|
||||
# On the other hand, "exit block" heuristics (predicting exit edges as not
|
||||
# taken) have good hitrate, but poor coverage, so only 3 branches have been
|
||||
# predicted. The "loop header" heuristic has problems, since it tends to
|
||||
# misspredict.
|

#

# The implementation of this script is somewhat brute force. My awk skills

# are limited.

# Update a local CVS tree from the GCC repository, with an emphasis

# on treating generated files correctly, so that autoconf, gperf et

# al are not required for the ``end'' user.
|

#
|

# By default all command-line options are passed to `cvs update` in

# addition to $UPDATE_OPTIONS (defined below). If the first parameter

# reads --nostdflags, $UPDATE_OPTIONS as well as this parameter itself
|

# are omitted.
|

#
|

# If the first parameter reads --patch, the second parameter is considered
|

# a patch file.
|

#
|

# If the first parameter is --touch, no cvs operation will be performed,

# only generated files that appear to be out of date in the local tree
|

# will be touched.
|

#
|

# If the first parameter is --list, a list of the generated files and

|
||||
This directory contains scripts that are used by the regression
|
||||
tester, <http://people.redhat.com/geoffk/gcc-regression/>.
|
||||
|
||||
The primary script is 'btest-gcc.sh'. This is the script that is run
|
||||
to actually test the compiler.
|
||||
|
||||
'objs-gcc.sh' takes a combined tree and builds (but does not test) the
|
||||
tools required for 'btest-gcc.sh'. It is run periodically to update
|
||||
the tools. This script is followed by running 'btest-gcc.sh' using
|
||||
the newly-build tools to check that they will not cause regressions.
|
||||
|
||||
'site.exp' is what $DEJAGNU points to when the regression tester runs
|
||||
these scripts.
|
||||
|
||||
Note that any changes made here need to be approved by the regression
|
||||
tester's maintainer (see MAINTAINERS). The changes will be used on
|
||||
the tester's next run, so `experimental' changes are very strongly
|
||||
discouraged :-).
