Bug #: 52074
Summary: ICE: RTL flag check: MEM_VOLATILE_P used with
unexpected rtx code 'plus' in extract_fixed_bit_field,
at expmed.c:1734
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: d...@gcc.gnu.org
seen with trunk 20120131, on a powerpc-linux-gnu biarch build, defaulting to
32bit.
Configured with: -v

--prefix=/usr/lib/gcc-snapshot

the 32bit libgo does build, but the 64bit build doesn't:
