            Bug ID: 113502
           Summary: gcc.target/aarch64/vect-early-break-cbranch.c testcase
                    is too sensitive
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: testsuite-fail
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64

Currently vect-early-break-cbranch.c fails.

For the failure we have:
```
FAIL: gcc.target/aarch64/vect-early-break-cbranch.c check-function-bodies f1
body: .*\tcmge  v[0-9]+.4s, v[0-9]+.4s, #0
\tumaxp v[0-9]+.4s, v[0-9]+.4s, v[0-9]+.4s
\tfmov  x[0-9]+, d[0-9]+
\tcbnz  x[0-9]+, \.L[0-9]+
.*
...
        cmge    v31.4s, v31.4s, #0
        umaxp   v31.4s, v31.4s, v31.4s
        fmov    x3, d31
        cbz     x3, .L11
```

As you can see it does not match as it is trying to match cbnz but cbz is
emitted.=
