--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jeff Law <l...@gcc.gnu.org>: https://gcc.gnu.org/g:2605daa6b896aed15dead194462725874f332c0a commit r15-7485-g2605daa6b896aed15dead194462725874f332c0a Author: Yangyu Chen <c...@cyyself.name> Date: Tue Feb 11 18:40:41 2025 -0700 RISC-V: Drop __riscv_vendor_feature_bits As discussed from RISC-V C-API PR #101 [1], As discussed in #96, current interface is insufficient to support some cases, like a vendor buying a CPU IP from the upstream vendor but using their own mvendorid and custom features from the upstream vendor. In this case, we might need to add these extensions for each downstream vendor many times. Thus, making __riscv_vendor_feature_bits guarded by mvendorid is not a good idea. So, drop __riscv_vendor_feature_bits for now, and we should have time to discuss a better solution.
