--- Comment #20 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Michael Matz <m...@gcc.gnu.org>: https://gcc.gnu.org/g:359209bdc7245f8768b5044acded8509545e4990 commit r15-3219-g359209bdc7245f8768b5044acded8509545e4990 Author: Michael Matz <m...@suse.de> Date: Thu Aug 22 17:03:56 2024 +0200 final: go down ASHIFT in walk_alter_subreg when experimenting with m68k plus LRA one of the changes in the backend is to accept ASHIFTs (not only MULT) as scale code for address indices. When then not turning on LRA but using reload those addresses are presented to it which chokes on them. While reload is going away the change to make them work doesn't really hurt (and generally seems useful, as MULT and ASHIFT really are no different). So just add it. PR target/116413 * final.cc (walk_alter_subreg): Recurse on AHIFT.
