Take this program:
#include <stdlib.h>
inline int F(){return rand();}
int main(void) {
return F();
}
This compiles fine with gcc using -O1 -O2 -O3.
But compile without optimising, and it fails to link as it can't find a
function 'F'.
Is it supposed to behave like that? I assume no discrete function F is
being generated because of the 'inline' attribute, but you'd think it
would ignore that if inlining wasn't enabled.
It compiles fine with or without 'inline' using tcc and bcc (my product).
Clang fails too, but clearly only because it has to duplicate gcc's
behaviour for drop-in compatability, even if it is crass.
(This is the actual program:
