Bug ID: 82786
Summary: aarch64 frame patch caused a number of target specific
test failures.
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sje at gcc dot gnu.org
CC: wdijkstr at arm dot com
Target Milestone: ---
Target: aarch64-*-*
This patch:
2017-10-26 Wilco Dijkstra <wdijk...@arm.com>
* config/aarch64/aarch64.c (aarch64_layout_frame):
Ensure LR is always stored at the bottom of the callee-saves.
Remove rarely used frame layout which saves callee-saves at top of
frame, so the store of LR can be used as a valid probe in all cases.
Caused several tests to fail:
