<pre>TGParser::ParseForeachDeclaration breaks early if TI is non-null, but we have
(dead) code later that uses it as part of an error message.
@arsenm - this looks like it was introduced in rGb79a25b12437
default: {
SMLoc ValueLoc = Lex.getLoc();
Init *I = ParseValue(nullptr);
if (!I)
return nullptr;
TypedInit *TI = dyn_cast<TypedInit>(I);
if (TI && isa<ListRecTy>(TI->getType())) {
ForeachListValue = I;
IterType = cast<ListRecTy>(TI->getType())->getElementType();
break;
}
if (TI) {
if (ParseRangePiece(Ranges, TI))
return nullptr;
break;
}
std::string Type;
if (TI)
Type = (Twine("' of type '") + TI->getType()->getAsString()).str();
Error(ValueLoc, "expected a list, got '" + I->getAsString() + Type + "'");
if (CurMultiClass) {
PrintNote({}, "references to multiclass template arguments cannot be "
"resolved at this time");
}
return nullptr;
}</pre>
