I've come across a need to know whether an option was set true, false or unspecified. If it is true I want to do one thing, if it is false I want to do something else and if it is unspecified I want to do nothing. ArgList::hasFlag is a convenient way to check true/false with a default value. An ArgList::hasFlag that returned Optional<bool> would allow checking the unspecified case.

No, I’m wrong. I think that bug is actually in ‘hasFlag’ itself. In ‘llvm/lib/Option/ArgList.cpp’ line #70: bool ArgList::hasFlag(OptSpecifier Pos, OptSpecifier PosAlias, OptSpecifier Neg, bool Default) const { if (Arg *A = getLastArg(Pos, PosAlias, Neg)) return A->getOption().matches(Pos) || A->getOption().matches(PosAlias); return Default; } This doesn’t match when ‘Neg’ is matched, and should probably be: bool ArgList::hasFlag(OptSpecifier Pos, OptSpecifier PosAlias, OptSpecifier Neg,...

Hi, I'm working on bringing up complete coverage for a Gentoo x32 "desktop" system. I've been cooking up quite a few patches for various packages to push upstream, but right now, the biggest blocker is the lack of support for building with/codegen targeting x32 in llvm/clang. Since the x32 patches were sent last year, I see support code has landed in LLVM, and basic handling of

Hi everybody, As you know, Cuda/NVPTX target has very limited support of the debug info in Clang/LLVM. Currently, LLVM supports only emission of the line numbers debug info. This is caused by limitations of the Cuda/NVPTX codegen. Clang/LLVM translates the source code to LLVM IR, which is then lowered to PTX (parallel thread execution) intermediate file. This PTX file represents special kind of
