Bug #: 50940
Summary: [4.7 Regression] ICE in extract_insn, at recog.c:2137
during bootstrap
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: markus@trippelsdorf.de
I've hit the following ICE during bootstrap on x86_64-pc-linux-gnu.
It only happens with the "-march=native" switch.
