--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Xi Ruoyao <xry...@gcc.gnu.org>: https://gcc.gnu.org/g:43d777078387ab2c4aabe526f6ee0ff13055e0b6 commit r14-11389-g43d777078387ab2c4aabe526f6ee0ff13055e0b6 Author: Xi Ruoyao <xry...@xry111.site> Date: Sun Mar 2 19:02:50 2025 +0800 LoongArch: Fix incorrect reorder of __lsx_vldx and __lasx_xvldx [PR119084] They could be incorrectly reordered with store instructions like st.b because the RTL expression does not have a memory_operand or a (mem) expression. The incorrect reorder has been observed in openh264 LTO build. Expand them to a (mem) expression instead of unspec to fix the issue. Closes: https://github.com/cisco/openh264/issues/3857 (cherry picked from commit 4856292f7a680ec478e7607f1b71781996d7d542) Edited to remove the loongarch.cc change which is not needed for gcc-14 branch. gcc/ChangeLog: PR target/119084 * config/loongarch/lasx.md (UNSPEC_LASX_XVLDX): Remove.
