--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, it's not a regression as it began with r228318 (w/ -fprofile-use):
$ gcc pr83512.c -O2 -freorder-blocks-algorithm=simple -c -fprofile-use
during RTL pass: bbro
pr83512.c: In function ‘w7’:
pr83512.c:15:1: internal compiler error: in df_compact_blocks, at
df-core.c:1729
