Subject: [gcc r13-3098] rs6000: Remove "wD" from *vsx_extract_<mode>_store
Date: Wed,  5 Oct 2022 19:12:59 +0000 (GMT)	[thread overview]
Message-ID: <20221005191259.75FA03858C2C@sourceware.org> (raw)

https://gcc.gnu.org/g:c3d131531a23c71e09c032d6222d0b5ff0eb8162

commit r13-3098-gc3d131531a23c71e09c032d6222d0b5ff0eb8162
Author: Segher Boessenkool <segher@kernel.crashing.org>
Date:   Mon Oct 3 22:43:48 2022 +0000

    rs6000: Remove "wD" from *vsx_extract_<mode>_store
    
    We can use "n" instead of "wD" if we simply test the value of the
    integer constant directly.

            * config/rs6000/vsx.md (*vsx_extract_<mode>_store): Use "n" instead of
            "wD" constraint.
