Bug #: 55596
Summary: [google] r191813 broke bootstrap-lto on google/gcc-4_7
branch
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: m...@use.net
r191813 broke bootstrap-lto on the google/gcc-4_7 branch. updating to one
revision prior fixes the issue. trying to cherry pick other LTO fixes from
trunk doesn't resolve the issues, only changes the error (to an ICE in
lto_fixup_prevailing_decls).

lto1: internal compiler error: tree code ‘H?E?H????@’ is not supported in LTO
streams
Let me know if providing the LTO temps would be useful.
