Bug ID: 63165
Summary: [5 Regression] r214816 breaks Java build and
435.gromacs
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: wschmidt at gcc dot gnu.org
CC: bergner at gcc dot gnu.org, pthaugen at gcc dot gnu.org,
segher at gcc dot gnu.org
Host: powerpc64le-unknown-linux-gnu
Target: powerpc64le-unknown-linux-gnu
Build: powerpc64le-unknown-linux-gnu
The powerpc64le regression tester fails to build gcc when the java language is
included, starting with revision 214816. The SPEC tester also fails to build
435.gromacs starting with the same revision. In both cases the symptoms are
the same:

We don't know yet whether this fails on big-endian as well; my guess would be
yes.
I'll work on getting preprocessed source to reproduce the problem.
