[Tinycc-devel] a macro problem (tcc 0.9.15)

[Mitchell N Charity]

I encountered the following while trying to compile parrot
(www.parrotcode.org) with tcc...

/*
  If wrap() is a macro, then tcc fails with:
     t04.c:31: field not found
  If wrap() is a function, then it works.

  tcc 0.9.15, RedHat 7.something
*/

typedef struct {
  int flags;
} A;
typedef struct {
  A obj;
} B;
typedef struct {
  B data;
} C;

extern C *x;

#define flags obj.flags

#if 1
#define wrap(expr) (expr)
#else
int wrap(int);
#endif

void demo(void) {
  wrap(x->data.flags);
}
