Bug ID: 97699
Summary: [11 regression] zero-scratch-regs tests fail on arm
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
Some of the recently added zero-scratch-regs-* tests fail on arm.
For instance when configuring GCC
--target arm-none-linux-gnueabihf
--with-mode arm
--with-cpu cortex-a9
--with-fpu neon-fp16
I can see:
FAIL: c-c++-common/zero-scratch-regs-10.c -Wc++-compat (test for excess
errors)
FAIL: c-c++-common/zero-scratch-regs-11.c -Wc++-compat (test for excess
errors)
FAIL: c-c++-common/zero-scratch-regs-9.c -Wc++-compat (test for excess
errors)
The logs say:
/gcc/testsuite/c-c++-common/zero-scratch-regs-10.c:77:1: sorry, unimplemented:
'-fzero-call-used_regs' not supported on this target
The other tests pass.
BTW, there's a typo in the error message, it should say
fzero-call-used-regs rather than fzero-call-used_regs (that is '-' instead of
'_' before 'regs')
