Subject: Allow tcc arguments to be read from @listfiles
This allows all @ prefixed arguments to be treated as listfiles
containing list of source files or tcc options where each one is on a
separate line. Can be used to benchmark compilation speed with
non-trivial amount of source files.
The impl of `tcc_parse_args` had to be moved to a new function that is
able to be called recursively w/ the original one remaining as a driver
of the new one. Listfiles parsing happens in a new
`args_parser_add_listfile` function that uses `tcc_open`/`tcc_close/inp`
for buffered file input.

Subject: Fix pragma once guard when compiling multiple source files
When compiling multiple source files directly to executable cached
include files guard was incorrectly checked for TOK_once in ifndef_macro
member.
If two source files included the same header guarded by pragma once, then
the second one erroneously skipped it as `cached_includes` is not cleared
on second `tcc_compile`
This only silences "cannot find library" error and allows Makefiles targeting gcc to not complain about missing libraries
If there is custom libm then standard handling applies.
There was already support for -dD option but in contrast -dM dumps only `#define` directives w/o actual preprocessor output.
The original -dD output differs from gcc output by additional comment in front of `#define`s so this quirk is left for -dM as well.
* Documentation is now in "docs".
* Source code is now in "src".
* Misc. fixes here and there so that everything still works.
I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...
functionality was broken some time ago and was removed
by the "tccpp: fix issues, add tests"
fix: LINE_MACRO_OUTPUT_FORMAT_NONE in pp_line()
means: output '\n' and not "don't output at all"
A new version of the MEM_DEBUG will be submitted next. This version is
not depend on the malloc_usable_size() presense in the libc and
print a places where a leaked chunks of memory was allocated.
* fix some macro expansion issues
* add some pp tests in tests/pp
* improved tcc -E output for better diff'ability
* remove -dD feature (quirky code, exotic feature,
didn't work well)
Based partially on ideas / researches from PipCet
Some issues remain with VA_ARGS macros (if used in a
rather tricky way).
Also, to keep it simple, the pp doesn't automtically
add any extra spaces to separate tokens which otherwise
would form wrong tokens if re-read from tcc -E output
(such as '+' '=') GCC does that, other compilers don't.
* cleanups
- #line 01 "file" / # 01 "file" processing
- #pragma comment(lib,"foo")
- tcc -E: forward some pragmas to output (pack, comment(lib))
- fix macro parameter list parsing mess from
a3fc543459a715d7143d
(some coffee might help, next time ;)
- introduce TOK_PPSTR - to have character constants as
written in the file (similar to TOK_PPNUM)
- allow '\' appear in macros
- new functions begin/end_macro to:
- fix switching macro levels during expansion
- allow unget_tok to unget more than one tok
- slight speedup by using bitflags in isidnum_table
Also:
- x86_64.c : fix decl after statements
- i386-gen,c : fix a vstack leak with VLA on windows
- configure/Makefile : build on windows (MSYS) was broken
- tcc_warning: fflush stderr to keep output order (win32)
Usage example: tcc -xc ex5.cgi
From a gcc docs:
You can specify the input language explicitly with the -x option:
-x language
Specify explicitly the language for the following input files
(rather than letting the compiler choose a default based on the file
name suffix). This option applies to all following input files until
the next -x option. Possible values for language are:
c c-header c-cpp-output
c++ c++-header c++-cpp-output
objective-c objective-c-header objective-c-cpp-output
objective-c++ objective-c++-header objective-c++-cpp-output
assembler assembler-with-cpp
ada
f77 f77-cpp-input f95 f95-cpp-input
java
-x none
Turn off any specification of a language, so that subsequent files
are handled according to their file name suffixes (as they are if -x
has not been used at all)
Win32, Win64, WinCE when executing "tcc -v". Example
$ ./i386-win-tcc -v
tcc version 0.9.26 (i386, mingw)
instead of the
tcc version 0.9.26 (i386, Win32)
There is a cpu info already about bits of the excution environment
And display C67 for the TCC_TARGET_C67
tcc version 0.9.26 (i386 Linux)

Displaing a "Hard Float" info for the ARM arch is restored. It was broken by the AArm64 patch.
With this option on a defines are included into the output
(inside comments). This will allow to debug a problems like:
In file included from math.c:8:
In file included from /usr/include/math.h:43:
/usr/include/bits/nan.h:52: warning: NAN redefined
tcc -E -P
do not output a #line directive, a gcc compatible option
tcc -E -P1
don't follow a gcc preprocessor style and do output a standard
#line directive. In such case we don't lose a location info when
we going to compile a resulting file wtith a compiler not
understanding a gnu style line info.
- remove -norunsrc switch
Meaning and usage (-run -norun...???) look sort of screwed. Also
general usefulness is unclear, so it was actually to support exactly
one (not even very interesting) test

tcc.c:
process.h:177:20: note: expected 'char * const*' but argument is of type 'char const*const*'
tccpe.c:
Add the possibility to use noname functions by ordinal.
use def file: "AliasName @n"
build-tcc.bat:
1. Enable 32 bits mode on 64 bits OS.
2. build doc.
_parseLibs.bat:
Convenient to use "*.def + *.c" instead of *.a, just use -l*

abitest now passes; however test1-3 fail in init_test. All other tests
pass. I need to re-test Win32 and Linux-x86.
I've added a dummy implementation of gfunc_sret to c67-gen.c so it
should now compile, and I think it should behave as before I created
gfunc_sret.
Modified tcctest.c so that it uses 'double' in place of 'long double'
with MinGW since this is what TCC does, and what Visual C++ does. Added
an option -norunsrc to tcc to allow argv[0] to be set independently of
the compiled source when using tcc -run, which allows tests that rely on
the value of argv[0] to work in out-of-tree builds.
Also added Makefile rules to automatically update out-of-tree build
Makefiles when in-tree Makefiles have changed.
- except for CONFIG_SYSROOT and CONFIG_TCCDIR
Strictly neccessary it is only for CONFIG_MULTIARCHDIR
because otherwise if it's in config.h it is impossible to
leave it undefined.
But it is also nicer not to use these definitions for
cross-compilers.
- Also:
lib/Makefile : include ../Makefile for CFLAGS
lib/libtcc1.c : fix an issue compiling tcc with tcc on x64
This replaces -> use instead:
-----------------------------------
- tcc_set_linker -> tcc_set_options(s, "-Wl,...");
- tcc_set_warning -> tcc_set_options(s, "-W...");
- tcc_enable_debug -> tcc_set_options(s, "-g");
parse_args is moved to libtcc.c (now tcc_parse_args).
Also some cleanups:
- reorder TCCState members
- add some comments here and there
- do not use argv's directly, make string copies
- use const char* in tcc_set_linker
- tccpe: use fd instead of fp
tested with -D MEM_DEBUG: 0 bytes left
tests/Makefile:
- print-search-dirs when 'hello' fails
- split off hello-run
win32/include/_mingw.h:
- fix for compatibility with mingw headers
(While our headers in win32 are from mingw-64 and don't have
the problem)
tiny_libmaker:
- don't use "dangerous" mktemp
