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

b8adf0090e Move asm label functions from tccasm.c to tccgen.c 
* Move functions parse_asm_str and asm_label_instr from tccasm.c to
  tccgen.c
* Remove CONFIG_TCC_ASM_LABEL macro as asm label are available on all
  archs.
See:
http://lists.nongnu.org/archive/html/tinycc-devel/2010-09/msg00026.html
for the rationale.

9b09fc376e Add support of asm label for functions. 
Add support for asm labels for functions, that is the ability to rename
a function at assembly level with __asm__ ("newname") appended in
function declaration.

c31dc7aa0c Fix casts from 32bit integer types to 64bit integer types. 
This bug was reported in
http://lists.gnu.org/archive/html/tinycc-devel/2010-08/msg00050.html

In this case, we should not emit any code when we cast from VT_FUNC to VT_PTR.

4ab4efd3a6 Revert "implemented C99 for loop with variable declaration" 
This reverts commit 433ecdfc9d.

The patch breaks e.g. with
    for ((i = 10); --i;);

In particular to check for a type decl. this is not sufficient:
    if (tok < TOK_UIDENT) {

A future approach to c99 loop variables might instead use:
    if (parse_btype(...)) {

plus refactor function decl() accordingly.

This reverts commit e9406c09a3.

We don't want errors for static local function pointers, such as:

8de9b7a631 Correctly support all unary expression with sizeof 
Unary expression can start with a parenthesis. Thus, the current test
to detect which sizeof form is being parsed is inaccurate. This patch
makes tcc able to handle things like sizeof (x)[1] where x is declared
as char x[5]; wich is a valid unary expression

6655e06ec8 Error out on bad char array initialization 
Error out with an explicit message when trying to initialize a
character array with something that's not a literal (optionally
enclosed in braces) as per C99 6.7.8:14; thanks to Antti-Juhani

c0620c8a00 avoid needless register save when storing structures 
When storing structs with a memcpy call in vstore(),
so far a needless entry remaining on the vstack
sometimes resulted in an useless store generated by
save_regs() in gfunc_call() for the memcpy routine.

6a004ed19f allow redefinition of func_old_type functions 
void *memcpy(void*, const void*, unsigned);

This gave an error if memcpy() has been used before
implicitely,  e.g. for structure passing etc.
