Bug #: 55112
Summary: internal compiler error: in simplify_subreg, at
simplify-rtx.c:5424
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: patr...@motec.com.au
Using cross compile gcc (x86_64->powerpc-eabispe) the following command line
results in an internal compiler error.
I've attached the problem object file.
Hope this is enough information, thanks.
