- would parse linker args in two different places
- would mess up "tcc -v ..." output:
tcc -v test.c
-> test.c
+> test.c
- would use function "tcc_load_alacarte()" to do the contrary of
what its name suggests.
This reverts commit 19a169ceb8.
A patch is implemented as suggested in tinycc-devel mail list.

Subject: [PATCH] Add --{no,}-whole-archive support
I resurrected the patch supplied to the mailing list in 2009
Since --whole-archive is a useful flag to get tcc working with
autotools, and of course in its own right, I suggest you have a look
at the patch and see if it is acceptable. I cannot see any suggestion
that it was actively rejected last time round, just no evidence that
it was ever added.
... for fast redeclaration checks
Also, check function parameters too:
void foo(int a) { int a; ... }
Also, try to fix struct/union/enum's on different scopes:
{ struct xxx { int x; };
{ struct xxx { int y; }; ... }}
and some (probably not all) combination with incomplete
declarations "struct xxx;"
Replaces 2bfedb1867
and 07d896c8e5
Fixes cf95ac399c
don't catch redefinition for local vars. With this option on
tcc accepts the following code:
int main()
{
int a = 0;
long a = 0;
}
But if you shure there is no problem with your local variables,
then a compilation speed can be improved if you have a lots of
the local variables (50000+)

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.
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.
remove non-existent or duplicate directories from include paths
if -fnormalize-inc-dirs is specified. This will help
to compile current coreutils package
tcc_normalize_inc_dirs: normally no problem to be absolutly
gcc compatible as long as it can be done the tiny way.
This reverts to the state before recent related commits and
reimplements a (small) part of it to fix the reported problem.
Also: Revert "parsing "..." sequence"
c3975cf27c
&& p[1] == '.'
is not a reliable way to lookahead
- avoid memory allocation by using its (int) token number
- avoid additional function parameter by using Attribute
Also: fix some strange looking error messages
include dirs are prepared as in gcc
- for each duplicate path keep just the first one
- remove each include_path that exists in sysinclude_paths
include_next streamlined by introducing inc_path_index
in the BufferedFile
* 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"
* 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)
