--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Uroš Bizjak from comment #1) > recip pass is converting to .RSQRT, target is just expanding what it gets. But it queries the target for support for RSQRT, but yeah, we lack to ask for "implicit" vs. "explicit" (via xmm intrinsics), so the target cannot possibly disable RSQRT expanders I guess.
