            Bug ID: 94204
           Summary: m68k: Provide builtins for mathemactical functions
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: adhemerval.zanella at linaro dot org
  Target Milestone: ---

For hard-float, GCC should support inline code generation for the trunc, floor,
ceil, isinf, finite, scalbn, isnan, scalbln, nearbyint, lrint, and sincos.

These optimization has been provided by glibc through mathinline.h headers and
glibc idea is to remove both the header and the optimizations [1].
