            Bug ID: 87368
           Summary: missing masking inline functions for VCVTSS2SD and
                    VCVTSD2SS
           Product: gcc
           Version: 8.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jbeulich at novell dot com
  Target Milestone: ---

Other than for the scalar float to/from integer conversion insns, the scalar
float <-> float ones allow a mask to be applied.

Out of the set of 5 each that the SDM shows, only _mm_cvt_roundsd_ss() and
_mm_cvt_roundss_sd() are actually available.
