[LLVMdev] MallocInst/CallInst bitcast,
Thanks very much. I only have one more question, (hopefully), which is, is
there a better way of finding the direction of stack growth other than:
static bool StackCmp(void *ptr) {
volatile int a;
return (void *)&a > ptr;
}
bool FindStackDirection() {
volatile int a;
return StackCmp((void *)&a);
}
Preferably one which isn't destroyed by optimization.
Thanks again,
Daniel

I suggest you turn the scalars into arra...

No problem, this is a better way to go. The MallocInst and FreeInst
instructions are about to be removed from LLVM IR.
