a1c12b9fb9 tests: add memory leak test
Also ...

tcctest.c:
- exclude stuff that gcc doesn't compile on windows.

libtcc.c/tccpp.c:
- use unsigned for memory sizes to avoid printf format warnings
- use "file:line: message" to make IDE error parsers happy.

tccgen.c: fix typo

c2ad11ac70 tccgen: fix long long -> char/short cast
This was causing assembler bugs in a tcc compiled by itself
at i386-asm.c:352 when ExprValue.v was changed to uint64_t:

    if (op->e.v == (int8_t)op->e.v)
        op->type |= OP_IM8S;

A general test case:

    #include <stdio.h>
    int main(int argc, char **argv)
    {
        long long ll = 4000;
        int i = (char)ll;
        printf("%d\n", i);
        return 0;
    }

Output was "4000", now "-96".

Also: add "asmtest2" as asmtest with tcc compiled by itself

0a624782df build: revert Makefiles to 0.9.26 state (mostly)
Except
- that libtcc1.a is now installed in subdirs i386/ etc.
- the support for arm and arm64
- some of the "Darwin" fixes
- tests are mosly unchanged

Also
- removed the "legacy links for cross compilers" (was total mess)
- removed "out-of-tree" build support (was broken anyway)

47e06c6d4e Reorganize the source tree.
* 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...

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)

d972472c53 Disable floating-point test for ARM soft-float
From: Matteo Cypriani <mcy@lm7.fr>
    Date: Fri, 5 Sep 2014 23:22:56 -0400
    Subject: Disable floating-point test for ARM soft-float

    tcc is not yet capable of doing softfloat floating-point operations on
    ARM, therefore we disable this test for these platforms. Note that tcc
    displays a warning to warn ARM users about this limitation

      void foo(void) { return 1; }
  This avoids an assertion failure in x86_64-gen.c, also.
  also fix tests2/03_struct.c accordingly

- Error: "memory full" - be more specific

- Makefiles: remove circular dependencies, lookup tcctest.c from VPATH

- tcc.h: cleanup lib, include, crt and libgcc search paths"
  avoid duplication or trailing slashes with no CONFIG_MULTIARCHDIR

41b3c7a507 Improved variable length array support.
VLA storage is now freed when it goes out of scope. This makes it
possible to use a VLA inside a loop without consuming an unlimited
amount of memory.

Combining VLAs with alloca() should work as in GCC - when a VLA is
freed, memory allocated by alloca() after the VLA was created is also
freed. There are some exceptions to this rule when using goto: if a VLA
is in scope at the goto, jumping to a label will reset the stack pointer
to where it was immediately after the last VLA was created prior to the
label, or to what it was before the first VLA was created if the label
is outside the scope of any VLA. This means that in some cases combining
alloca() and VLAs will free alloca() memory where GCC would not.

1caee8ab3b Sorted out CMake on x86-64 and fixed silly XMM# bug introduced when working on Win64 stdargs.
I removed the XMM6/7 registers from the register list because they are not used
on Win64 however they are necessary for parameter passing on x86-64. I have now
restored them but not marked them with RC_FLOAT so they will not be used except
for parameter passing.

55ea6d3fc1 x86-64 ABI fixes.
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.

2bbfaf436f Tests in abitest.c now work on Win32.
I expect that Linux-x86 is probably fine. All other architectures
except ARM are definitely broken since I haven't yet implemented
gfunc_sret for these, although replicating the current behaviour
should be straightforward.

ce5e12c2f9 Added ABI compatibility tests with native compiler using libtcc.
Only one test so far, which fails on Windows (with MinGW as the native
compiler - I've tested the MinGW output against MSVC and it appears the
two are compatible).

I've also had to modify tcc.h so that tcc_set_lib_path can point to the
directory containing libtcc1.a on Windows to make the libtcc dependent
tests work. I'm not sure this is the right way to fix this problem.

e31579b076 Fixed tests on Windows (including out-of-tree problems)
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.

After 40a54c43 (Repair bounds-checking runtime), and in particular
5d648485 (Now btest pass!) `make test` was broken on ARCH != i386,
because I've changed btest to unconditionally run on all arches.

But bounds-checking itsels is only supported on i386 and oops...

b2a02961b4 Add support for __builtin_frame_address(level)
Continuing d6072d37 (Add __builtin_frame_address(0)) implement
__builtin_frame_address for levels greater than zero, in order for
tinycc to be able to compile its own lib/bcheck.c after
cffb7af9 (lib/bcheck: Prevent __bound_local_new / __bound_local_delete
from being miscompiled).

I'm new to the internals, and used the most simple way to do it.
Generated code is not very good for levels >= 2, compare

                gcc                         tcc

    level=0     mov    %ebp,%eax            lea    0x0(%ebp),%eax

    level=1     mov    0x0(%ebp),%eax       mov    0x0(%ebp),%eax

    level=2     mov    0x0(%ebp),%eax       mov    0x0(%ebp),%eax
                mov    (%eax),%eax          mov    %eax,-0x10(%ebp)
                                            mov    -0x10(%ebp),%eax
                                            mov    (%eax),%eax

    level=3     mov    0x0(%ebp),%eax       mov    0x0(%ebp),%eax
                mov    (%eax),%eax          mov    (%eax),%ecx
                mov    (%eax),%eax          mov    (%ecx),%eax

But this is still an improvement and for bcheck we need level=1 for
which the code is good.

For the tests I had to force gcc use -O0 to not inline the functions.
And -fno-omit-frame-pointer just in case.

If someone knows how to improve the generated code - help is
appreciated.

Thanks,
Kirill

d54e24cc0e tests: Minor adjustments selecting which tests are run on each platform.
The intent is for 'make test' to pass cleanly on each platform, and thus easier
spotting of regressions. Linux is best supported by most tests running and
passing. Mac OSX passes mosts tests that do not make/link with binary files,
due to lack of mach-o file support.

!!! I have very limited knowledge of Windows platform, and cannot comment why
all tests(1) fail. I have posted to newsgroup asking for someone to test
Windows platform.

ab936aeb8c cleanup some partially broken patches
- tests/Makefile:
  fix commit de54586d5b
  This hunk it unrelated to the other changes (which are about MacOSX).
  It is not useful and partially wrong.  Optional tests are meant to
  stay optional, btest would work only for i386

- tcc.h:
  fix commit c52d79605a by unknown
  The message says it's for MINTW but the patch has obviously
  no effect for MINGW (which defines __GNUC__).  However the patch
  seems useful for MSC which however needs _strto(u)i64 with underscore.

- Makefile:
  fix commit 5280293d6b

  from tcc.o and libtcc.a/so

de54586d5b Further changes improving the OSX build. Everything builds. libtest passes.
Other tests still have issues, currently with weak linking.

One of the primary stumbling blocks on OSX is the lack of support for
mach-o binaries. Therefore all tcc usage on OSX has to be limited to elf
binaries, presumably produced by tcc itself.

Therefore I had to enable building of tiny_libmaker for OSX. Then changed
the make to use tcc and tiny_libmaker to compile the tcclib1.

In order to compile the tests, specifically the parts that use weak linking,
I have had to define MACOSX_DEPLOYMENT_TARGET to 10.2, which seems like a
hack, but extensive searching seems to indicate that this is the only way
to make apple gcc allow weak linking. Using any other value, bigger or smaller
breaks weak linking.

Also added _ANSI_SOURCE define required by some OSX headers, and some cosmetic
gitignore changes. I believe these changes should not impact other platforms.

8ca8b08890 Patch attempting to build OSX TinyCC.
Applied patch found on stackoverflow (link below). I also found some
related changes that looked like logically needed. The stackoverflow
changes addressed only two registers which were breaking a compile.
However reading the code in the same file shows two other register
accesses that, while not breaking the build, should have the same fix.

http://stackoverflow.com/questions/3712902/problems-compiling-tcc-on-os-x/3713144#3713144

The test driver was changed by changing 'cp -u' into 'cp' as '-u' is not
supported on mac osx.

I found that osx build required the WITHOUT_LIBTCC define. I suspect the
reason for this is tcc unability to handle mach-o files. In order to
properly address this I had to change 'configure' to propagate target os
name to Makefile.

Current state is that simple tests work, but not the whole 'make test'
suite runs.

To the best of my knowledge, these changes should not impact other
platforms.
