--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The comment above ix86_hardreg_mov_ok doesn't match the implementation, it
doesn't prevent it before reload but before and during reload (LRA). So I'd
have expected:
--- gcc/config/i386/i386.c 2021-11-22 10:07:01.336225481 +0100
+++ gcc/config/i386/i386.c 2021-11-22 18:54:22.288643063 +0100
@@ -19367,7 +19367,8 @@ ix86_hardreg_mov_ok (rtx dst, rtx src)

}
but, that doesn't really fix it and it is unclear what LRA is unhappy about to
me.
