--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I will have a look.
+FAIL: gcc.dg/memcpy-6.c (test for warnings, line 25)
+FAIL: gcc.dg/memcpy-6.c scan-tree-dump-not optimized "memcpy"
+FAIL: gcc.dg/memcpy-6.c scan-tree-dump-not optimized "memmove"
fold_copy_8 and fold_move_8 are no longer folded, that's to be expected with
MOVE_MAX and DImode types not being involved directly. The r12-3482 change
would have newly folded those. fold_move_8 is also not expanded inline
by RTL expansion. GCC 11 seems to fold both.
The gcc.dg/ipa/remref-7.c one is probably spurious (it's a new testcase).
