commit f4bc29810476dd9e964a49cd8e1b57b454e6d409 Author: Dongyan Chen <[email protected]> Date: Mon Sep 15 21:49:15 2025 -0600 RISC-V: Imply zicsr for sdtrig and ssstrict extensions. This patch implies zicsr for sdtrig and ssstrict extensions. According to the riscv-privileged spec, the sdtrig and ssstrict extensions are privileged extensions, so they should imply zicsr. gcc/ChangeLog: * config/riscv/riscv-ext.def: Imply zicsr.
