The author of the following files is licongtian <licongtian at 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.
