jiang bcf60562e0 The number of rows to display warning is wrong 
For example:
#define TOK_ASM_weak TOK_WEAK1
#define TOK_ASM_weak TOK_WEAK
Output:
C8.c:3: warning: TOK_ASM_weak redefined

jiang a94ed43094 Improved '\ n' output effect (# pragma pack (push, 8), # pragma pack (pop)) 2014-05-17 12:06:18 +08:00
jiang 196c999515 1 macro_push and macro_pop work I made a mistake, no matter the definition does not define can be macro_push. 
And the modified tcctest.c test
2, pack: in the compiler under the mode of s1->ppfp, I have no clear ideas1->ppfp
Some advice thank you Roy to me.This patch, I hope I can pass the Roy test

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!

jiang e647c3137d Fix x86-64 vla 
For example, it should look like this
High stack
-------------
----- Func_ret_sub
------------
---- Vla stack
-------------
---- Known loc
--------------
Low

Increased loc_stack () function is used for temporary stack management, call save_reg (), released by load ()
Like this
Before use
High
----- Known loc
----
---
----
---- Pop_stack
Low
loc_stack (size, 1)
After use
High
----- Known loc
---- Pop_stack
---
----
----
Low

jiang 5b52a44b52 gen_putz () and struct_copy (), is to reduce the third-party call that 
generates faster code tcc
Now only for x86-64
parse_number also to reduce the reliance on third-party libraries, allowing
faster analysis tcc
