--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Max Filippov <jcmvb...@gcc.gnu.org>: https://gcc.gnu.org/g:e94c6dbfb57a862dd8a8685eabc4886ad1aaea25 commit r13-1015-ge94c6dbfb57a862dd8a8685eabc4886ad1aaea25 Author: Max Filippov <jcmvb...@gmail.com> Date: Tue Jun 7 21:01:01 2022 -0700 gcc: xtensa: fix PR target/105879 split_double operates with the 'word that comes first in memory in the target' terminology, while gen_lowpart operates with the 'value representing some low-order bits of X' terminology. They are not equivalent and must be dealt with differently on little- and big-endian targets. gcc/ PR target/105879 * config/xtensa/xtensa.md (movdi): Rename 'first' and 'second' to 'lowpart' and 'highpart' so that they match 'gen_lowpart' and 'gen_highpart' bitwise semantics and fix order of highpart and lowpart depending on target endianness.
