...;nontemporal" and the assembler doesn't like it. Do I need to use named metadata? That would be rather inconvenient. The problem is this code in llvm-as: int LLParser::ParseLoad(Instruction *&Inst, PerFunctionState &PFS, bool isVolatile) { Value *Val; LocTy Loc; unsigned Alignment = 0; bool AteExtraComma = false; if (ParseTypeAndValue(Val, Loc, PFS) || ParseOptionalCommaAlign(Alignment, AteExtraComma)) return true; [...] } /// ParseOptionalCommaAlign /// ::= /// ::= ',' align 4 /// /// This returns with AteExtraComma set...
