opt crashes in llvm/lib/Target/PowerPC/PPCTargetMachine.cpp:251 #172812
Description
When running opt on this following IR, opt crashes.
I am not sure whether this is a valid case. If using opt in this way is not appropriate, I am open to closing this issue.
llvm version 3186ca2

define void @_Z4testv() {
entry:
store ptr inttoptr (i32 42 to ptr), ptr @a, align 4
