Thereby, it allows 128-bit vector to be enabled by default in the loongarch64 backend.

The remain constraints (`k`, `m`, `ZB`, `ZC`) will be addedlater as they are a little more complex than the others.f: A floating-point register (if available).l: A signed 16-bit constant.I: A signed 12-bit constant (for arithmetic instructions).K: An unsigned 12-bit constant (for logic instructions).For now, no need to support register alias (e.g. `$a0`) in llvm asclang will correctly decode the usage of register name aliases intotheir official names. And AFAIK, the not yet upstreamed `rustc` forLoongArch will always use official register names (e.g. `$r4`).[1] https://gcc.gnu.org/onlinedocs/gccint/Machine-Constraints.htmlDifferential Revision: https://reviews.llvm.org/D134157 List of files: /llvm-project/llvm/test/CodeGen/LoongArch/inline-asm-constraint-error.ll Thu, 22 Sep 2022 12:03:01 +0000 Weining Lu <luweining@loongson.cn>
