[LLVMdev] E = L->begin() in LoopVectorize
Hi,
I'm studying loop vectorizer. I don't understand the code yet. But
it looks not right to assign L->begin() to E. Is it a typo?
Thanks,
Liang

[LLVMdev] E = L->begin() in LoopVectorize
Looking at it now, curious why no tests failed.

[LLVMdev] Dereferencing NULL pointer in IndVarSimplify.cpp?
Hi,
Here is the code in IndVarSimplify.cpp.
SmallVector<WeakVH, 16> DeadInsts;
while (!DeadInsts.empty())
if (Instruction *Inst =
dyn_cast_or_null<Instruction>(&*DeadInsts.pop_back_val()))
RecursivelyDeleteTriviallyDeadInstructions(Inst, TLI);
Since DeadInsts.pop_back_val() is WeakVH which could hold a NULL
pointer, the expression,
