This patch tries to make it compatible regardingLoongArch specific operand modifiers.GCC supports many modifiers [2], but it seems that only x86 and msp430are documented [3][4]. I don't know if any other modifiers are beingused except the 'z' in Linux [5].[1]: https://clang.llvm.org/compatibility.html#inline-asm[2]: https://github.com/gcc-mirror/gcc/blob/master/gcc/config/loongarch/loongarch.cc#L4884-L4911[3]: https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#x86Operandmodifiers[4]: https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#msp430Operandmodifiers[5]: https://github.com/torvalds/linux/blob/master/arch/loongarch/include/asm/cmpxchg.h#L17Differential Revision: https://reviews.llvm.org/D136841 List of files: /llvm-project/llvm/test/CodeGen/LoongArch/inline-asm-operand-modifiers.ll Mon, 31 Oct 2022 01:15:29 +0000 Weining Lu <luweining@loongson.cn>
