Thomas Preud'homme 4b8470f3ae Revert "Disable C99 VLA when alloca is unavailable." 
This reverts commit e3e5d4ad7a.

Joe Soroka b0c50fbd4d update VT_STRUCT_SHIFT for new VT_VLA 2011-02-04 14:33:38 -08:00
grischka 2775173d4d fix crash with get_tok_str() in skip() 
crash was triggered by numbers etc. as unexpected token, i.e.
everything that requires additional information with the token.

Thomas Preud'homme e3e5d4ad7a Disable C99 VLA when alloca is unavailable. 
* Disable C99 VLA detection when alloca is unavailable and protect the
  new reference to TOK_alloca in decl_initializer in order to compile
  and run for architecture without working alloca.

  Not all code of C99 VLA is commented as it would required many ifdef
  stanza. Just the detection is commented so that VT_VLA is never set
  any type and the C99 VLA code is compiled but never called. However
  vpush_global_sym(&func_old_type, TOK_alloca) in decl_initializer needs
  to be protected by an ifdef stanza as well because it uses TOK_alloca.

* include alloca and C99 VLA tests according to availability of
  TOK_alloca instead of relying on the current architecture
 2011-02-04 15:24:48 +01:00
Thomas Preud'homme af26ac56bf Make TOK_alloca available for x86-64 
TOK_alloca is now available on x86-64 so make put definition of
TOK_alloca outside the BCHECK conditional macro definition but test if
arch is i386 or x86-64. This makes C99 VLA works (understand compile) on
x86-64.

Joe Soroka 6839382480 asmtest: avoid testing against complex nop alignment in gas 
.align #,0x90 in gas ignores the 0x90 and outputs any kind
of nop it feels like.  the one avoided by this patch is a 7
byte nop, which gas has been doing since at least 1999:
http://sourceware.org/ml/binutils/1999-10/msg00083.html

In order to match what gas does, we would need to make
code alignment target-specific, import a lot of code, and
face the question: exactly which gas {version,target,tune}
combo are we trying to match?  see i386_align_code in:
http://sourceware.org/cgi-bin/cvsweb.cgi/src/gas/config/tc-i386.c?annotate=1.460&cvsroot=src

The smart noppery is turned on via the special casing of 0x90

Sergei Trofimovich 0a50e6c933 tcc.c: fix an error when you build an object file with '-pthread' key set 
The problem was partially fixed by Henry in the following patch:

    tcc.c: skip -lpthread when -c option specified

But that patch had one brawback: it is sensitive to argument order,
as decision is taken during commandline parsing:

    $ tcc -c a.c -o a.o -pthread # 1. works fine
    tcc: error: file 'a.c' not found

    $ tcc -pthread -c a.c -o a.o # 2. blows
    tcc: error: cannot specify libraries with -c

This patch fixes case 2.

Shinichiro Hamaji 0ed7ba3f5e Support struct arguments with stdarg.h 
- add __builtin_va_arg_types to check how arguments were passed
- move most code of stdarg into libtcc1.c
- remove __builtin_malloc and __builtin_free
- add a test case based on the bug report

Shinichiro Hamaji d457addfc3 Fix for the previous commit. 
R_X86_64_PLT32 for .so doesn't need DLL relocation.
 2010-12-28 16:52:21 +09:00
Shinichiro Hamaji 0ae39f1957 Handle r_addend and R_X86_64_PLT32 properly. 
- r_addend should be applied for PLT entries as well
- R_X86_64_PLT32 should be handled just like R_X86_64_PC32
- spec says GLOB_DAT and JUMP_SLOT don't need r_addend (not tested)
  http://www.x86-64.org/documentation/abi.pdf

Now we can -run ELF objects generated by GCC.

removed this cp command. However, it was necessary to pass tests on x86-64
because include/stdarg.h is different from GCC's definition on x86-64.
