Bug #: 52937
Summary: [4.8 Regression] ICE in several cpu2006 benchmarks
with -fprofile-use (assert in get_loop_body)
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: wschm...@gcc.gnu.org
CC: berg...@vnet.ibm.com, rguent...@suse.de
Host: powerpc64-linux
Target: powerpc64-linux
Build: powerpc64-linux
Created attachment 27135
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27135
SPEC cpu2006 configuration file used for failing build
403.gcc, 445.gobmk, and 454.calculix all fail to build on trunk when applying
profile data (-fprofile-use). I apologize for not providing a reduced test
case, but I'm not sure how to do that when profile data is involved. I'm
attaching my cpu2006 .cfg file; hopefully that will help to reproduce.
Richi, copying you since this appears similar to
