[Bug math/21912] New: Optimize float math functions with FMA


https://sourceware.org/bugzilla/show_bug.cgi?id=21912

            Bug ID: 21912
           Summary: Optimize float math functions with FMA
           Product: glibc
           Version: 2.27
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
                CC: andrew.n.senkevich at gmail dot com
  Target Milestone: ---
            Target: x86-64

The following double math functions:

e_asin.c
e_atan2.c
e_exp.c
e_log.c
e_pow.c
s_atan.c
s_sin.c
s_tan.c

are optimized with FMA.  Should the corresponding float versions be optimized
with FMA?
