--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by LuluCheng <chengl...@gcc.gnu.org>: https://gcc.gnu.org/g:bf0b32d7929f8b4b15b21658d572b89ded03d8f8 commit r12-10303-gbf0b32d7929f8b4b15b21658d572b89ded03d8f8 Author: Lulu Cheng <chengl...@loongson.cn> Date: Fri Mar 15 16:41:20 2024 +0800 LoongArch: gcc12: Implement option save/restore. LTO option streaming and target attributes both require per-function target configuration, which is achieved via option save/restore. We implement TARGET_OPTION_{SAVE,RESTORE} to switch the la_target context in addition to other automatically maintained option states (via the "Save" option property in the .opt files). PR target/113233 gcc/ChangeLog: * config/loongarch/genopts/loongarch.opt.in: Mark options with the "Save" property. * config/loongarch/loongarch-opts.cc (loongarch_update_gcc_opt_status): Update the value of the la_target to global_options. * config/loongarch/loongarch-opts.h (loongarch_update_gcc_opt_status): Add a function declaration. * config/loongarch/loongarch.cc (loongarch_option_override_internal): Call the function loongarch_update_gcc_opt_status. (loongarch_option_save): New functions. (loongarch_option_restore): Likewise. (TARGET_OPTION_SAVE): Define macro. (TARGET_OPTION_RESTORE): Likewise. * config/loongarch/loongarch.opt: Regenerate.
