[PATCH] D107608: [AArch64] Implement FCOPYSIGN for SVE.

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I'm not really paying attention to SVE2 at the moment, but I guess it's possible to use bsl there.

Like I note in the comments, it would be possible to use FNEG_MERGE_PASSTHRU... but fabs+cmp+fneg isn't really better than this sequence.  I briefly tried using VSELECT directly, but we're missing a bunch of combines to make that work well.
