Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

/* This program is the user interface to the C compiler and possibly to
other compilers. It is used because compilation is a complicated procedure
which involves running several programs and passing temporary files between
them, forwarding the users switches to those programs selectively,
and deleting the temporary files at the end.
CC recognizes how to compile each input file by suffixes in the file names.
Once it knows which kind of compilation to perform, the procedure for
compilation is specified by a string called a "spec". */

/* Specs are strings containing lines, each of which (if not blank)
is made up of a program name, and arguments separated by spaces.
The program name must be exact and start from root, since no path
is searched and it is unreliable to depend on the current working directory.
Redirection of input or output is not supported; the subprograms must
accept filenames saying what files to read and write.
In addition, the specs can contain %-sequences to substitute variable text
or for conditional text. Here is a table of all defined %-sequences.
Note that spaces are not generated automatically around the results of
expanding these sequences; therefore, you can concatenate them together
or with constant text in a single argument.
%% substitute one % into the program name or argument.
%i substitute the name of the input file being processed.
%b substitute the basename of the input file being processed.
This is the substring up to (and not including) the last period
and not including the directory.

%gSUFFIX
substitute a file name that has suffix SUFFIX and is chosen
once per compilation, and mark the argument a la %d. To reduce
exposure to denial-of-service attacks, the file name is now
chosen in a way that is hard to predict even when previously
chosen file names are known. For example, `%g.s ... %g.o ... %g.s'
might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches
the regexp "[.A-Za-z]*" or the special string "%O", which is
treated exactly as if %O had been pre-processed. Previously, %g
was simply substituted with a file name chosen once per compilation,
without regard to any appended suffix (which was therefore treated
just like ordinary text), making such attacks more likely to succeed.
%uSUFFIX
like %g, but generates a new temporary file name even if %uSUFFIX
was already seen.
%USUFFIX
substitutes the last file name generated with %uSUFFIX, generating a
new one if there is no such last file name. In the absence of any
%uSUFFIX, this is just like %gSUFFIX, except they don't share
the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s'
would involve the generation of two distinct file names, one
for each `%g.s' and another for each `%U.s'. Previously, %U was
simply substituted with a file name chosen for the previous %u,
without regard to any appended suffix.

The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost.

%d marks the argument containing or following the %d as a
temporary file name, so that that file will be deleted if CC exits
successfully. Unlike %g, this contributes no text to the argument.
%w marks the argument containing or following the %w as the
"output file" of this compilation. This puts the argument
into the sequence of arguments that %o will substitute later.
%W{...}
like %{...} but mark last argument supplied within
as a file to be deleted on failure.
%o substitutes the names of all the output files, with spaces
automatically placed around them. You should write spaces
around the %o as well or the results are undefined.
%o is for use in the specs for running the linker.
Input files whose names have no recognized suffix are not compiled
at all, but they are included among the output files, so they will
be linked.
This brings rev 1.2 (FREEBSD_NATIVE) and rev 1.5 (mixed ELF/aout support) into EGCS 1.1.2.
1999-08-29 23:53:46 +00:00
%O substitutes the suffix for object files. Note that this is
handled specially when it immediately follows %g, %u, or %U,
because of the need for those to form complete file names. The
handling is such that %O is treated exactly as if it had already
been substituted, except that %g, %u, and %U do not currently
support additional SUFFIX characters following %O as they would
following, for example, `.o'.

%p substitutes the standard macro predefinitions for the
current target machine. Use this when running cpp.
%P like %p, but puts `__' before and after the name of each macro.
(Except macros that already have __.)
This is for ANSI C.
%I Substitute a -iprefix option made from GCC_EXEC_PREFIX.
%s current argument is the name of a library or startup file of some sort.
Search for that file in a standard list of directories
and substitute the full name found.
%eSTR Print STR as an error message. STR is terminated by a newline.
Use this when inconsistent options are detected.
%x{OPTION} Accumulate an option for %X.
%X Output the accumulated linker options specified by compilations.
%Y Output the accumulated assembler options specified by compilations.
%Z Output the accumulated preprocessor options specified by compilations.
%v1 Substitute the major version number of GCC.
(For version 2.5.n, this is 2.)
%v2 Substitute the minor version number of GCC.
(For version 2.5.n, this is 5.)
%a process ASM_SPEC as a spec.

%| output "-" if the input for the current command is coming from a pipe.
%* substitute the variable part of a matched option. (See below.)
Note that each comma in the substituted string is replaced by
a single space.
%{S} substitutes the -S switch, if that switch was given to CC.
If that switch was not specified, this substitutes nothing.
Here S is a metasyntactic variable.
%{S*} substitutes all the switches specified to CC whose names start
with -S. This is used for -o, -D, -I, etc; switches that take
arguments. CC considers `-o foo' as being one switch whose
name starts with `o'. %{o*} would substitute this text,
including the space; thus, two arguments would be generated.

%{S*:X} substitutes X if one or more switches whose names start with -S are
specified to CC. Note that the tail part of the -S option
(i.e. the part matched by the `*') will be substituted for each
occurrence of %* within X.
%{S:X} substitutes X, but only if the -S switch was given to CC.
%{!S:X} substitutes X, but only if the -S switch was NOT given to CC.
%{|S:X} like %{S:X}, but if no S switch, substitute `-'.
%{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'.
%{.S:X} substitutes X, but only if processing a file with suffix S.
%{!.S:X} substitutes X, but only if NOT processing a file with suffix S.

%[Spec] as above, but put __ around -D arguments
The conditional text X in a %{S:X} or %{!S:X} construct may contain
other nested % constructs or spaces, or even newlines. They are
processed as usual, as described above.
The -O, -f, -m, and -W switches are handled specifically in these
constructs. If another value of -O or the negated form of a -f, -m, or
-W switch is found later in the command line, the earlier switch
value is ignored, except with {S*} where S is just one letter; this
passes all matching options.

Note that it is built into CC which switches take arguments and which
do not. You might think it would be useful to generalize this to
allow each compiler's spec to say which switches take arguments. But
this cannot be done in a consistent fashion. CC cannot even decide
which input files have been specified without knowing which switches
take arguments, and it must know which input files to compile in order
to tell which compilers to run.
CC also knows implicitly that arguments starting in `-l' are to be
treated as compiler output files, and passed to the linker in their
proper position among the other output files. */

Only do a.out/elf switching on i386 family
1998-03-09 04:13:31 +00:00
#if defined(FREEBSD_NATIVE) && defined(__i386__)
First round of changes to support generation of assembler for the old a.out gas and the binutils gas (elf or a.out) with a single compiler. This uses other infrastructure not yet committed, in order to support both a.out and elf it needs to be able to get to both a.out and elf gas, ld, libs, crt* etc. So for now, the support is pretty much dormant. The new freebsd.h file is based on the old freebsd-elf.h file (which has a long lineage, right back through linux and svr4 files). The change is pretty dramatic from a gcc internals standpoint as it overrides a lot of definitions in order to generate different output based on target mode. There is potential for screw-ups, so please be on the lookout - gcc's configuration mechanism wasn't really meant for this kind of thing. It's believed to compile world etc just fine under both a.out and elf, can handle global constructors and destructors, handles the differences in a.out and elf stabs, and what sections things like exceptions go in. The initial idea came from i386/osfrose.h which is a dual rose/elf format target. These two are not as diverse as a.out and elf it would seem. The cc front-end uses external configuration to determine default object format (still being thrashed out, so read the source if you want to see it so far), and has a '-aout' and '-elf' override command line switch. There are some other internal switches that can be accessed, namely -maout, -mno-aout, -munderscores and -mnounderscores. The underscore and local symbol prefixing rules are controllable seperately to the output format. (ie: it's possible to generate a.out without the _ prefixes on symbols and also to generate elf with the _ prefixes. This isn't quite optimal, but does seem to work pretty well, except the linkers don't always recognise the local symbols without their normal names) The default format is a.out (still), nobody should see any major changes.

#ifdef FREEBSD_NATIVE
Only do a.out/elf switching on i386 family
1998-03-09 04:13:31 +00:00
#if defined(__i386__)
First round of changes to support generation of assembler for the old a.out gas and the binutils gas (elf or a.out) with a single compiler. This uses other infrastructure not yet committed, in order to support both a.out and elf it needs to be able to get to both a.out and elf gas, ld, libs, crt* etc. So for now, the support is pretty much dormant. The new freebsd.h file is based on the old freebsd-elf.h file (which has a long lineage, right back through linux and svr4 files). The change is pretty dramatic from a gcc internals standpoint as it overrides a lot of definitions in order to generate different output based on target mode. There is potential for screw-ups, so please be on the lookout - gcc's configuration mechanism wasn't really meant for this kind of thing. It's believed to compile world etc just fine under both a.out and elf, can handle global constructors and destructors, handles the differences in a.out and elf stabs, and what sections things like exceptions go in. The initial idea came from i386/osfrose.h which is a dual rose/elf format target. These two are not as diverse as a.out and elf it would seem. The cc front-end uses external configuration to determine default object format (still being thrashed out, so read the source if you want to see it so far), and has a '-aout' and '-elf' override command line switch. There are some other internal switches that can be accessed, namely -maout, -mno-aout, -munderscores and -mnounderscores. The underscore and local symbol prefixing rules are controllable seperately to the output format. (ie: it's possible to generate a.out without the _ prefixes on symbols and also to generate elf with the _ prefixes. This isn't quite optimal, but does seem to work pretty well, except the linkers don't always recognise the local symbols without their normal names) The default format is a.out (still), nobody should see any major changes.

First round of changes to support generation of assembler for the old a.out gas and the binutils gas (elf or a.out) with a single compiler. This uses other infrastructure not yet committed, in order to support both a.out and elf it needs to be able to get to both a.out and elf gas, ld, libs, crt* etc. So for now, the support is pretty much dormant. The new freebsd.h file is based on the old freebsd-elf.h file (which has a long lineage, right back through linux and svr4 files). The change is pretty dramatic from a gcc internals standpoint as it overrides a lot of definitions in order to generate different output based on target mode. There is potential for screw-ups, so please be on the lookout - gcc's configuration mechanism wasn't really meant for this kind of thing. It's believed to compile world etc just fine under both a.out and elf, can handle global constructors and destructors, handles the differences in a.out and elf stabs, and what sections things like exceptions go in. The initial idea came from i386/osfrose.h which is a dual rose/elf format target. These two are not as diverse as a.out and elf it would seem. The cc front-end uses external configuration to determine default object format (still being thrashed out, so read the source if you want to see it so far), and has a '-aout' and '-elf' override command line switch. There are some other internal switches that can be accessed, namely -maout, -mno-aout, -munderscores and -mnounderscores. The underscore and local symbol prefixing rules are controllable seperately to the output format. (ie: it's possible to generate a.out without the _ prefixes on symbols and also to generate elf with the _ prefixes. This isn't quite optimal, but does seem to work pretty well, except the linkers don't always recognise the local symbols without their normal names) The default format is a.out (still), nobody should see any major changes.
