Summary: ppc64 build failure - Unrecognized opcode: `sldi' (and

Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: g...@intrepid.com

On several PPC64 systems, we are seeing the following build failure.

The failures above use the gcc-4.8-20120729 snapshot which is based on svn
revision 189947.
The configure target is: powerpc64-unknown-linux-gnu
This was built on a rather old (FC6) system running on a Mac G5, but we have
seen it also fail on newer PPC64 systems.
