commit r17-1359-g218780d6c7b93cec4d7088079820491b6b8f2771 Author: Kito Cheng <[email protected]> Date: Thu Jun 4 22:49:37 2026 +0800 RISC-V: Specify cmodel in OPTION_DEFAULT_SPECS We have supported --with-cmodel for a while and set the default via TARGET_DEFAULT_CMODEL. That works well in general, but not for multilib, because GCC cannot detect the cmodel for the current multilib correctly that way. So we still need to specify the default cmodel in OPTION_DEFAULT_SPECS. gcc/ChangeLog: * config/riscv/riscv.h (OPTION_DEFAULT_SPECS): Specify default cmodel.
