--- Comment #32 from Jakub Jelinek <jakub at gcc dot gnu.org> --- https://gcc.gnu.org/g:eec8da328cf1f91db302ab4cee803e269e68ad33 commit r16-8584-geec8da328cf1f91db302ab4cee803e269e68ad33 Author: Surya Kumari Jangala <[email protected]> Date: Sat Apr 11 12:19:45 2026 -0500 Revert "rs6000: Disassemble opaque modes using subregs to allow optimizations" This reverts commit 69a2c243dd2cf9f77150c0eb86dfbc0931876bc1 to resolve the issue reported in PR124804. Let's close this as fixed, if PowerPC maintainers want to resolve this differently for GCC 17, a new PR can be opened to track it. But I think if it uses SUBREGs, they need to use the documented behavior of SUBREG_BYTE preserving the memory ordering (which is saidly PDP-endian in little endian mode if I understand it right).
