bool  IsOffloadEntry,
const RegionCodeGenTy CodeGen 

Helper to emit outlined function for 'target' directive.

DDirective to emit.
ParentNameName of the function that encloses the target region.
OutlinedFnOutlined function value to be defined by this call.
OutlinedFnIDOutlined function ID value to be defined by this call.
IsOffloadEntryTrue if the outlined function is an offload entry.
CodeGenLambda codegen specific to an accelerator device. An outlined function may not be an entry if, e.g. the if clause always evaluates to false.
