commit r14-11559-g80ab25142565e83477af7c3e57f0a4dcf51b9659 Author: Xianmiao Qu <cooper...@linux.alibaba.com> Date: Wed Sep 18 07:35:12 2024 -0600 [PATCH 1/2] RISC-V: Fix the outer_code when calculating the cost of SET expression. I think it is a typo. When calculating the 'SET_SRC (x)' cost, outer_code should be set to SET. gcc/ * config/riscv/riscv.cc (riscv_rtx_costs): Fix the outer_code when calculating the cost of SET expression.
