[Bug middle-end/24729] function calls created by builtins do not make use of inline definitions

[ghazi at gcc dot gnu dot org]

------- Comment #5 from ghazi at gcc dot gnu dot org  2005-11-24 17:03 -------
Here's a version of the testcase that doesn't rely on _unlocked functions since
25022 inhibits the unlocked transformations.  Compile at -O2 with and without
-DPUTCHAR_DIRECT to see the effect.  Using putchar directly makes use of the
extern inline and transforms into _IO_putc, whereas the printf call only gets
as far as turning into putchar.


#include <stdio.h>
#undef putchar

int main ()
{
#ifdef PUTCHAR_DIRECT
  putchar('\n');
#else
  printf ("\n");
#endif
  return 0;
}
