Bug ID: 71443
Summary: [7 regression] test case
gcc.dg/plugin/must-tail-call-2.c reports error
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: wdijkstr at arm dot com
Target Milestone: ---
There are 2 new failures in the tail-call-2.c test on recent trunk builds:
FAIL: gcc.dg/plugin/must-tail-call-2.c -fplugin=./must_tail_call_plugin.so
(test for errors, line 32)
FAIL: gcc.dg/plugin/must-tail-call-2.c -fplugin=./must_tail_call_plugin.so
(test for excess errors)
The error reported is:
/home/wdijkstr/gcc/gcc/testsuite/gcc.dg/plugin/must-tail-call-2.c: In function
'test_2_caller':^M
/home/wdijkstr/gcc/gcc/testsuite/gcc.dg/plugin/must-tail-call-2.c:32:10: error:
cannot tail-call: argument must be passed by copying^M
The argument is a large structure which is passed by reference on AArch64. So
it looks like the test needs to allow for this possibility. This appears
related to PR71293 for Power.
