--- Comment #1 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by H.J. Lu <h...@gcc.gnu.org>: https://gcc.gnu.org/g:d2798598c4fcf2281921df3c2b7b1d16a171fa03 commit r14-8883-gd2798598c4fcf2281921df3c2b7b1d16a171fa03 Author: H.J. Lu <hjl.to...@gmail.com> Date: Mon Feb 5 19:48:48 2024 -0800 x86: Update constraints for APX NDD instructions 1. The only supported TLS code sequence with ADD is addq foo@gottpoff(%rip),%reg Change je constraint to a memory operand in APX NDD ADD pattern with register source operand. 2. The instruction length of APX NDD instructions with immediate operand: op imm, mem, reg may exceed the size limit of 15 byes when non-default address space, segment register or address size prefix are used. Add jM constraint which is a memory operand valid for APX NDD instructions with immediate operand and add jO constraint which is an offsetable memory operand valid for APX NDD instructions with immediate operand. Update APX NDD patterns with jM and jO constraints. gcc/ PR target/113711 PR target/113733 * config/i386/constraints.md: List all constraints with j prefix.
