            Bug ID: 113542
           Summary: gcc.target/arm/bics_3.c regression after change for
                    pr111267
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roger at nextmovesoftware dot com
  Target Milestone: ---

This patch is a placeholder for tracking the reported failures of
FAIL: gcc.target/arm/bics_3.c scan-assembler-times bics\tr[0-9]+, r[0-9]+,
r[0-9]+ 2
FAIL: gcc.target/arm/bics_3.c scan-assembler-times bics\tr[0-9]+, r[0-9]+,
r[0-9]+, .sl #2 1
See https://linaro.atlassian.net/browse/GNU-1117

Alas, I've been unable to reproduce the failure on cross compilers to either
arm-linux-gnueabihf nor armv8l-unknown-linux-gnueabihf, so I suspect that
there's some configuration option or compile-time flag I'm missing that's
required to trigger these failures (which I'm hoping is "missed optimizatio=
n"
rather than "wrong code").

Hopefully, filing this PR provides a mechanism to allow folks to help me
investigate this issue.  My apologies for the temporary inconvenience.
Setting the component to "rtl-optimization" until this is confirmed to be a
target (ARM backend) issue.=
