Bug ID: 64156
Summary: Subversion id 218266 breaks the big-endian 64-bit
PowerPC build (wilco.dijkstra at arm dot com's mod to
ira-costs.c)
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Host: powerpc64-unknown-linux-gnu
Target: powerpc64-unknown-linux-gnu
Build: powerpc64-unknown-linux-gnu
Subversion id 218266 breaks the big-endian 64-bit PowerPC build. Please either
revert the patch or fix it so that the PowerPC now builds once again. You can
see the failure by building a cross compiler. It fails when building the
32-bit libgcc on the _powisf module. If I remove the -fPIC option, it will
compile the module.
Here is the failure message:
