Duncan, Can't we drop the extern from the patch and use something like... void foo(void) __attribute__(externally_visible); as described in http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html?

I don't think so. "Redefines it locally" is not the same as giving

Duncan,

Thanks Nick. I've been pursuing Gao's technique but can't seem to get opt to remove obviously dead code from even the following trivial example: int mult(int a, int b){ return a*b; } int main(void){ return 0; } While mult is never called it still is not removed. I just can't seem to get opt to understand it's seeing the whole program so it can remove this
