--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Andi Kleen <[email protected]>: https://gcc.gnu.org/g:b95c8a32f5387e360d7e867bcc8947094e8531e6 commit r16-8913-gb95c8a32f5387e360d7e867bcc8947094e8531e6 Author: Andi Kleen <[email protected]> Date: Wed May 13 16:40:16 2026 -0700 PR124316: Fix ptwrite assembler mode Add explicit assembler mode for cases when the argument is not unambigious. This avoids cases where a user specified 64bit ptwrite ends up being 32bit due to an ambigious argument. PR target/124316 gcc/ChangeLog: * config/i386/i386.md (ptwrite): Add explicit mode to instruction. gcc/testsuite/ChangeLog: * gcc.target/i386/pr124316.c: New test.
