| -- This package contains the generic functions which are instantiated with |
| -- predefined integer and real types to generate the runtime exponentiation |
| -- functions called by expanded code generated by Expand_Op_Expon. This |
| -- version of the package contains routines that are compiled with overflow |
| -- checks enabled, so they are called for exponentiation operations which |
| -- require overflow checking |
| |
| package System.Exp_Gen is |
| pragma Pure (System.Exp_Gen); |
