is this a bug in PruneEH?
...rce:
extern unsigned int donut;
void f1();
void f2();
void f1()
{
unsigned int *magic = &donut;
if (*magic != 286529877) {
f2();
}
}
void f2() {
/* Loop here forever if application is built with wrong version of ROM image */
while(1) {
;
}
}
The -O2 level PruneEH pass uses SimplifyFunction() which contains this code:
for (BasicBlock::iterator I = BB->begin(), E = BB->end(); I != E; )
if (CallInst *CI = dyn_cast<CallInst>(I++))
if (CI->doesNotReturn() && !CI->isMustTailCall() &&
!isa<UnreachableInst>(I)) {...
