Lu <hjl.to...@gmail.com> Date: Fri Jan 31 12:29:04 2025 +0800 x86: Handle TARGET_INDIRECT_BRANCH_REGISTER for -fno-plt If TARGET_INDIRECT_BRANCH_REGISTER is true, indirect call and jump should use register, not memory. Update Bs, Bw and Bz constraints to disable indirect call over memmory if TARGET_INDIRECT_BRANCH_REGISTER true, change x32 call over GOT slot to call over register and also disable sibcall over memory. gcc/ PR target/118713 * config/i386/constraints.md (Bs): Always disable if TARGET_INDIRECT_BRANCH_REGISTER is true.
