<pre>Function stripPointerCastsAndOffsets() at Value.cpp will handle the
AddrSpaceCast case as follows:
static Value *stripPointerCastsAndOffsets(Value *V) {
...
} else if (Operator::getOpcode(V) == Instruction::BitCast ||
Operator::getOpcode(V) == Instruction::AddrSpaceCast) {
V = cast<Operator>(V)->getOperand(0);
} else if (GlobalAlias *GA = dyn_cast<GlobalAlias>(V)) {
...
This does not look correct, since according to LLVM langref, "The
‘addrspacecast‘ instruction converts the pointer value ptrval to type pty2. It
can be a no-op cast or a complex value modification, depending on the target
and the address space pair."
Should we remove the check of Instruction::AddrSpaceCast here?</pre>
