--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started to ICE with r195902:
pr60508.c: In function ‘fn1’:
pr60508.c:29:1: error: unrecognizable insn:
(insn 95 94 88 3 (set (reg/v:QI 4 si [orig:84 i ] [84])
(subreg:QI (subreg:SI (reg:DI 2 cx [126]) 0) 0)) pr60508.c:14 -1
(nil))
pr60508.c:29:1: internal compiler error: in extract_insn, at recog.c:2164
On 4.8 branch with release checking the ICE is:
pr60508.c:29:1: internal compiler error: in subreg_get_info, at rtlanal.c:3278
Starting with r206023 it is:
pr60508.c:29:1: internal compiler error: in lra_set_insn_recog_data, at
lra.c:1081
rather than ICE about unrecognizable insn.
