            Bug ID: 109880
           Summary: [14 regression]
                    gcc.target/powerpc/fold-vec-extract-int.p8.c fails
                    after r14-916-g9417b30499ce09
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite

The test case may just need updating.  The ones that count assembler
instructions can be fragile.

--- Comment #1 from Peter Bergner <bergner at gcc dot gnu.org> ---
Confirmed.  The difference I see is:

gcc.target/powerpc/fold-vec-extract-int.p8.c: \\mrldicl\\M found 5 times
FAIL: gcc.target/powerpc/fold-vec-extract-int.p8.c scan-assembler-times
\\mrldicl\\M 7

...which makes sense, since the rldicl is used as a zero extend, so it does
look like just an instruction count update is needed.

Ajit, can you please confirm the 2 missing rldicl were removed because of zero
extends?  Bill's build seems pretty normal, so did you not see this failure
during your testing?

--- Comment #2 from Ajit Kumar Agarwal <aagarwa at gcc dot gnu.org> ---
Yes these are redundant zero extend and can be removed.

I will update the tests and send the patch for review.

Yeah, marking it resolved, thanks for reminding.
