Bug#173513: Wishlist: Inline constant function pointers

[Ian Turner <vectro@pipeline.com>]

Package: gcc-3.2
Version: 1:3.2.1-0pre3
Severity: wishlist

Currently GCC will not inline a call of a function pointer that is known 
at compile time. For example, the following code will still result in 
the instruction "call funk" when run with -finline-functions on i386:

#include <stdio.h>

static char* funk() {
  return "Hello World.\n";
}

static void funky(char*(*func)()) {
  printf("%s", func());
}

void main() {
  funky(funk);
}

Although the call to funky is inlined, the call to funk is not, because 
in the source code it appears as a call of a function pointer. But as a 
consequence of funky being inlined, it would be possible to inline funk 
as well.
