- /* The US Software GOFAST library requires special optabs support.
- There is no negation libcall, and several others have names different
- from gcc. This file consolidates the support in one place.
-
- The basic plan is to leave gcc proper alone and via some hook fix things
- after the optabs have been set up. Our main entry point is
- INIT_GOFAST_OPTABS. */
