            Bug ID: 117036
           Summary: [SH] add __builtin_sh_fsca, __builtin_sh_fsrra
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: olegendo at gcc dot gnu.org
  Target Milestone: ---

Currently the compiler will convert std::sin, std::cos, 1/std::sqrt into fsca
and fsrra instruction when e.g. --fast-math is enabled.

However, there are cases where users want to emit those instructions directly,
regardless of optimization settings.  E.g. to implement platform specific
fast-math functions/libraries.
