1: The new patch for the other machines still have the problem.
2: libcrt Rename (what if gcc had libcrt as well)
3: parse_number exact problem
4: VT_VLS is to allow tcc
Compile the following
int b = 9;
struct st {
int a;
int b [b]
};
struct st st1;
st1.b [8] = 9;
printf ("% d \ n", st1.b [8]);
tcc a problem. Due to problems in front, and now can not be improved
5: they commit much, bug difficult to lock, you can not let other people help develop.
6: ('\ t') too
Thanks to Michael and Ray
Their criticism I have benefited!

on several variables can be connected to commit in the register. I am worried whether tcc can run the os. Since my machine is ubuntu 64 bits I can test my machine.

The procedure calling standard for ARM architecture mandate the use of
the base standard for variadic function. Therefore, hgen float aggregate
must be returned via stack when greater than 4 bytes and via core
registers else in case of variadic function.
This patch improve gfunc_sret() to take into account whether the
function is variadic or not and make use of gfunc_sret() return value to
determine whether to pass a structure via stack in gfunc_prolog(). It
also take advantage of knowing if a function is variadic or not move
float result value from VFP register to core register in gfunc_epilog().

Move the logic to do a test of an integer value (ex if (0)) out of
arch-specific code to tccgen.c to avoid code duplication. This also
fixes test of long long value which was only testing the bottom half of
such values on 32 bits architectures.

On ARM with hardfloat calling convention, structure containing 4 fields
or less of the same float type are returned via float registers. This
means that a structure can be returned in up to 4 double registers in a
structure is composed of 4 doubles. This commit adds support for return
of structures in several registers.

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.

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.

Should fix some warnings wrt. access out of array bounds.
tccelf.c: fix "static function unused" warning
x86_64-gen.c: fix "ctype.ref uninitialzed" warning and cleanup
tcc-win32.txt: remove obsolete limitation notes.

Also use uppercase TRUE/FALSE instead of true/false

We need 32bit relocations for code and 64bit for debug info.
Introduce a new macro R_DATA_PTR to distinguish the two usages.
