================
Comment at: clang/lib/Parse/ParseStmtAsm.cpp:746-755
ParseTypeQualifierListOpt(DS, AR_VendorAttributesParsed);
// GNU asms accept, but warn, about type-qualifiers other than volatile.
if (DS.getTypeQualifiers() & DeclSpec::TQ_const)
Diag(Loc, diag::warn_asm_qualifier_ignored) << "const";
if (DS.getTypeQualifiers() & DeclSpec::TQ_restrict)
Diag(Loc, diag::warn_asm_qualifier_ignored) << "restrict";
----------------
I think in a follow up commit, I'll just delete this (the call to `ParseTypeQualifierListOpt` and subsequent `warn_asm_qualifier_ignored` emission); making it a parse error to put type qualifiers after the keyword `asm`, which would match the behavior of GCC, and not waste time looking for and parsing type qualifiers. It maybe made sense when `ParseTypeQualifierListOpt` was being abused to parse `volatile`, but this patch fixes that.
