[Bug math/22884] New: RISCV fmax/fmin handle signalling NANs incorrectly


https://sourceware.org/bugzilla/show_bug.cgi?id=22884

            Bug ID: 22884
           Summary: RISCV fmax/fmin handle signalling NANs incorrectly
           Product: glibc
           Version: 2.27
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: dj at redhat dot com
  Target Milestone: ---

RISCV hardware fmax/fmin treat sNANs as qNANs; thus, a call like fmax(sNAN,4)
would return 4 instead of qNAN.

See bz 20947 for generic background.
