[Tinycc-devel] bug report: no idea how to describe the bug, but has a minimum demo

Thu, 06 Apr 2023 15:17:04 -0700 

Source Code:


```c


#define VSF_MCONNECT(a, b)              
        a##b


#if 1
#define VSF_MREPEAT(__COUNT, __MACRO, ...)      
VSF_MCONNECT(VSF_MREPEAT, __COUNT)(__MACRO, ##__VA_ARGS__)
#define VSF_MREPEAT0(  __MACRO, ...)
#define VSF_MREPEAT1(  __MACRO, ...)          
  VSF_MREPEAT0(  __MACRO, ##__VA_ARGS__)   __MACRO(  
0, ##__VA_ARGS__)
#else
#define VSF_MREPEAT(__COUNT, __MACRO, __PARAM)  VSF_MCONNECT(VSF_MREPEAT, 
__COUNT)(__MACRO, __PARAM)
#define VSF_MREPEAT0(  __MACRO, __PARAM)
#define VSF_MREPEAT1(  __MACRO, __PARAM)        
VSF_MREPEAT0(  __MACRO, __PARAM)   __MACRO(  0, __PARAM)
#endif


#define __PM_DIV_(_N, _D)     VSF ## _D ## DIV_ ## _N = (_N),
typedef enum vsf_pm_divider_t {
    VSF_MREPEAT(1, __PM_DIV_, MAIN)
} vsf_pm_divider_t;


int main(int argc, char **argv)
{
    return 0;
}



```


Compiler output, tcc is compiled form the git top:
>>> /usr/local/bin/tcc -v
tcc version 0.9.27 mob:e7262ac 2023-03-23T20:02:19+01:00 (x86_64 Linux)
>>> /usr/local/bin/tcc -o main -c main.c
main.c:15: error: '}' expected (got "DIV_0")



pre-compile output with -E options:


# 1 "main.c"
# 1 "<command line&gt;" 1
# 2 "main.c" 2
# 14 "main.c"
typedef enum vsf_pm_divider_t {
&nbsp; &nbsp; &nbsp;VSFMAIN DIV_0 = (0),
} vsf_pm_divider_t;


int main(int argc, char **argv)
{
&nbsp; &nbsp; return 0;
}



If change the #if 1 to #if 0, it will be ok to compile the source code.
