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.
Organization
Your organization. You can leave this field blank.
Confidential
This field is unused and set to 'no'. All bug reports,
including sample code, are publicly accessible.
Synopsis
A one-line description of the problem; something like "GCC 2.95
does not foo", "objc crashes when doing bar".
Severity
Can be one of
critical
GCC is completely not operational; no work-around known.
serious
GCC is not working properly; a work-around is possible.
non-critical
Report indicates minor problem.
Priority
Can be one of
high
A solution is necessary as soon as possible. This is
reserved to GCC maintainers.
medium
The problem should be solved in the next release.
low
The problem should be solved in a future release.
Category
This indicates the GCC subproject which is affected by the
problem. Currently, it can be one of
ada
A problem with the Ada compiler, libraries or tools.
bootstrap
GCC fails to bootstrap. This should be filed only if a
bootstrap failure prevails for an extended period of time
(at least one week) on any platform (and possibly
not-so-common conditions like a read-only srcdir), or
non-mainstream platforms.
c++
A problem with the C++ compiler.
c
A problem with the C compiler.
debug
A problem with generating debugging information.
fortran
A problem with the Fortran compiler.
java
A problem with the Java compiler.
libf2c
A problem in the Fortran runtime library.
libgcj
A problem in the Java runtime library.
libobjc
A problem in the Objective C runtime library.
libstdc++
A problem in the Standard C++ runtime library.
middle-end
A problem in the internal compiler passes.
objc
A problem with the Objective C compiler.
optimization
A problem only occurring under optimization.
preprocessor
A problem with the C preprocessor.
target
The problem depends on the specific target architecture.
web
There is an error or omission on the Web pages.
other
The problem is in none of these categories.
Class
A classification of the problem; one of
doc-bug
The documentation is incorrect.
accepts-illegal
GCC fails to reject erroneous code.
rejects-legal
GCC gives an error message for correct code.
wrong-code
The machine code generated by GCC is incorrect.
ice-on-legal-code
GCC gives an Internal Compiler Error (ICE) for correct
code.
ice-on-illegal-code
GCC gives an ICE instead of reporting an error.
pessimizes-code
GCC misses an important optimization opportunity.
sw-bug
Software bug of some other class than above.
change-request
A feature in GCC is missing.
support
I need help with GCC.
Release
GCC version, as obtained from 'gcc -v' (one line).
Environment
Information about your operating system version, hardware
architecture, and environment settings that affect GCC.
Description
Precise description of the problem. You should put the error
messages printed by GCC here; source code should go into the
next section.
How-To-Repeat
Please put the complete source code to reproduce the problem
here. The gccbug script currently does not support file
attachments. Instead, if you have multiple files, include them
uuencoded (compressing them before if they are large). If you
use gnatsweb, you can use the file attachments button instead.
Fix
How to correct or work around the problem, if known (multiple
lines).

<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
just to the person who requested it, unless explicitly told so. If
possible, please include in this follow-up all the information you had
supplied in the incomplete bug report (including the preprocessor
output), so that the new bug report is self-contained.</p>
<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>
<h1><a name="manage">Managing Bugs (GNATS and the test-suite)</a></h1>
<p>This section contains information mostly intended for GCC
contributors.</p>
<p>If you find a bug, but you are not fixing it (yet):</p>
<ol>
<li>Create a (minimal) test-case.</li>
<li>Add the test-case to our test-suite, marking it as XFAIL unless
the bug is a regression.</li>
<li>Add a bug report referencing the test-case to GNATS.</li>
</ol>
<p>If you fix a bug for which there is already a GNATS entry:</p>
<ol>
<li>Remove the XFAIL on the test-case.</li>
<li>Close the bug report in GNATS.</li>
</ol>
<p>If you find a bug, and you are fixing it right then:</p>
<ol>
<li>Create a (minimal) test-case.</li>
<li>Add the test-case to our test-suite, marking it as PASS.</li>
<li>Check in your fixes.</li>
</ol>

<h1><a name="known">Frequently Reported Bugs in GCC</a></h1>
<h2><a name="fortran">Fortran</a></h2>
<p>Fortran bugs are documented in the G77 manual rather than
explicitly listed here. Please see
<a href="http://gcc.gnu.org/onlinedocs/g77/Trouble.html">Known Causes of
Trouble with GNU Fortran</a> in the G77 manual.</p>
<hr />
<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 &lt;stdio.h&gt;
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.

<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:11: warning: preprocessing directive not recognized within
macro arg<br />
test.c:11: warning: preprocessing directive not recognized within
macro arg<br />
test.c: In function `foo':<br />
test.c:6: undefined or invalid # directive<br />
test.c:8: undefined or invalid # directive<br />
test.c:9: parse error before `24'<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>&lt;string.h&gt;</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>
&amp;
<a href="http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/lwg-defects.html">
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>&lt;cstdlib&gt;</code> rather than <code>&lt;stdlib.h&gt;</code>).
The <code>.h</code> names are still available, but are deprecated.</li>
<li><code>&lt;strstream&gt;</code> is deprecated, use
<code>&lt;sstream&gt;</code> instead.</li>
<li><code>streambuf::seekoff</code> &amp;
<code>streambuf::seekpos</code> are private, instead use
<code>streambuf::pubseekoff</code> &amp;
<code>streambuf::pubseekpos</code> respectively.</li>
<li>If <code>std::operator &lt;&lt; (std::ostream &amp;, 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>
</ul>
<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.
</p>
<dl>
<dt>Covariant return types</dt>
<dd>We do not implement non-trivial covariant returns. We also generate
incorrect virtual function tables for trivial covariance. Although
trivial covariance will work, it is incompatible with the ABI. GNATS PR
3706 tracks this problem.</dd>
</dl>
<h3><a name="nonbugs">Non-bugs</a></h3>
<p>Here are some features that have been reported as bugs, but are
not.</p>
<dl>
<dt>Nested classes can access private types of the containing
class.</dt>
<dd><p>G++ now implements type access control on member types. Defect
report 45 clarifies that nested classes are members of the class they
are nested in, and so are granted access to private members of that
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
pointer to incomplete (other than <code><i>cv</i> void *</code>) in
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 &lt;iostream&gt;<br />
<br />
int main() {<br />
<br />
double min = 0.0;<br />
double max = 0.5;<br />
double width = 0.01;<br />
std::cout &lt;&lt; (int)(((max - min) / width) - 1) &lt;&lt;
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
<a href="http://www.validlab.com/goldberg/paper.ps">this paper</a>
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&lt;::X&gt;</code>.
</p>
<p>
The reason is that the standard mandates that the sequence
<code>&lt;:</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&lt;
::X&gt;</code>, i.e. place a space between the opening angle bracket
and the scope operator.
</p></dd>
</dl>
<h3><a name="missing">Missing features</a></h3>
<p>We know some things are missing from G++.</p>
<dl>
<dt>The <code>export</code> keyword is not implemented.</dt>
<dd><p>Most C++ compilers (G++ included) do not yet implement
<code>export</code>, which is necessary for separate compilation of
template declarations and definitions. Without <code>export</code>, a
template definition must be in scope to be used. The obvious
workaround is simply to place all definitions in the header
itself. Alternatively, the compilation unit containing template
definitions may be included from the header.</p></dd>
<dt>Two stage lookup in templates is not implemented.</dt>
<dd><p>[14.6] specifies how names are looked up inside a template. G++
does not do this correctly, but for most templates this will not be
noticeable.</p></dd>
</dl>
<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>
<pre>
struct A{};
struct B{
A a;
A f1(bool);
};
A B::f1(bool b)
{
if (b)
return (A());
return a;
}
</pre>
<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

#
#
# 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 ...)
# (only defined in each library's main Makefile).
# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
# (only defined in each multilib subdir).
# FIXME: Multilib is currently disabled by default for everything other than
# newlib. It is up to each target to turn on multilib support for the other
# libraries as desired.
# We have to handle being invoked by both Cygnus configure and Autoconf.
#
# Cygnus configure incoming variables:
# srcdir, subdir, host, arguments
#
# Autoconf incoming variables:
# srcdir, host, ac_configure_args
#
# We *could* figure srcdir and host out, but we'd have to do work that
# our caller has already done to figure them out and requiring these two
# seems reasonable.

* mh-irix4: merged changes from progressive.
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)
* mh-solaris2: Add new configuration for Solaris 2 (sysv, no ranlib)
Fri Apr 10 23:10:08 1992 Fred Fish (fnf@cygnus.com)
* mh-ncr3000: Add new configuration for NCR 3000.

@ -0,0 +1,23 @@
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)
#
#HEURISTICS BRANCHES (REL) HITRATE COVERAGE (REL)
#opcode 2889 83.7% 94.96%/ 97.62% 7516383 75.3%
#pointer 246 7.1% 99.69%/ 99.86% 118791 1.2%
#loop header 449 13.0% 98.32%/ 99.07% 43553 0.4%
#first match 3450 100.0% 89.92%/ 97.27% 9979782 100.0%
#loop exit 924 26.8% 88.95%/ 95.58% 9026266 90.4%
#error return 150 4.3% 64.48%/ 86.81% 453542 4.5%
#call 803 23.3% 51.66%/ 98.61% 3614037 36.2%
#loop branch 51 1.5% 99.26%/ 99.27% 26854 0.3%
#noreturn call 951 27.6% 100.00%/100.00% 1759809 17.6%
#
# 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
# their dependencies will be printed; --help prints this message.
#
# Examples:
#
# contrib/gcc_update -r gcc_latest_snapshot
# contrib/gcc_update -A
# contrib/gcc_update --nostdflags -P -r gcc-2_95-branch gcc/testsuite
# contrib/gcc_update --patch some-patch

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 :-).
