[PATCH v2] LoongArch: Fix inconsistent description in *sge_

The constraint of op[1] is inconsistent with the output template. gcc/ChangeLog: * config/loongarch/loongarch.md (define_insn "*sge_"): Fix inconsistency error. --- Update in v2: Remove useless support for op[1] is const_imm12_operand. ---

Re: [PATCH] LoongArch: Fix inconsistent description in *sge_

Thanks for the feedback. The comparison between a const_imm12_operand and (const_int 1) does indeed perform a universal process of constant folding before any tree based optimization. I will fix it in patch v2. 在 2024/3/4 下午5:18, Xi Ruoyao 写道: On Mon, 2024-03-04 at 11:03 +0800, Guo Jie
