The author of the following files is licongtian <licongtian@loongson.cn>: - clang/lib/Basic/Targets/LoongArch.cpp - llvm/lib/Target/LoongArch/LoongArchAsmPrinter.cpp - llvm/lib/Target/LoongArch/LoongArchISelLowering.cpp The files mentioned above implement InlineAsm for LSX and LASX as follows: - Enable clang parsing LSX/LASX register name, such as $vr0. - Support the case which operand type is 128bit or 256bit when the constraints is 'f'. - Support the way of specifying LSX/LASX register by using constraint, such as "={$xr0}". - Support the operand modifiers 'u' and 'w'. - Support and legalize the data types and register classes involved in LSX/LASX in the lowering process.
