Hi, What I wanna change is "gcc/common/config/loongarch/loongarch-common.cc", and the patch is automatically generated by "git gcc-commit-mklog". Is it necessary to  to remove "common/" ? Thanks for the review. 在 2023/9/8 下午4:06, Xi Ruoyao 写道: On Fri, 2023-09-08 at 10:00 +0800, Guo Jie wrot

[PATCH] RISC-V: Fix incorrect nregs calculation for VLS modes
