grischka cf32bb8812 Revert "--whole-archive support"
- 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.

seyko 19a169ceb8 --whole-archive support
A patch is implemented as suggested in tinycc-devel mail list.

    From: Reuben Thomas
    Date: Thu, 31 Jul 2014 16:52:53 +0100
    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.

Vlad Vissoultchev 224236f57c Improve hash performance
- better `TOK_HASH_FUNC`
- increases `hash_ident` initial size to 16k (from 8k)
- `cstr_cat` uses single `realloc` + `memcpy`
- `cstr_cat` can append terminating zero
- `tok_str_realloc` initial size to 16 (from 8)
- `parse_define` uses static `tokstr_buf`
- `next` uses static `tokstr_buf`
- fixes two latent bugs (wrong deallocations in libtcc.c:482 and
  tccpp.c:2987)

seyko 989b5ee8ae Allow tcc arguments to be read from @listfiles
From: Vlad Vissoultchev
    Date: Tue, 12 Apr 2016 20:43:15 +0300
    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.

seyko b5b3e89f9e Fix pragma once guard
From: Vlad Vissoultchev
    Date: Mon, 11 Apr 2016 01:26:32 +0300
    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`

Vlad Vissoultchev e946eb2a41 Implement -dM preprocessor option as in gcc
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...

grischka 30df3189b1 tccpp: fix issues, add tests
* 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
    a3fc543459
    a715d7143d
    (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)

seyko a13f183e4c ability to compile multiple *.c files with -c switch

2015-04-12 15:39:48 +03:00
seyko 0536407204 ability to specify a type of the input file with the -x switch
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)
