This procedure expands the necessary call. procedure Expand_Vax_Comparison (N : Node_Id); -- The node N is an arithmetic comparison node where the types to be -- compared are in Vax float format. This procedure expands the necessary -- call. procedure Expand_Vax_Conversion (N : Node_Id); -- The node N is a type conversion node where either the source or the -- target type, or both, are Vax floating-point type. procedure Expand_Vax_Foreign_Return (N : Node_Id); -- The node N is a call to a foreign function that returns a Vax float -- value in a floating point register. Wraps the call in an asm stub -- that moves the return value to an integer location on Alpha/VMS, -- noop everywhere else. procedure Expand_Vax_Real_Literal (N : Node_Id); -- The node N is a real literal node where the type is a Vax floating-point -- type. This procedure rewrites the node to eliminate the occurrence of -- such constants. procedure Expand_Vax_Valid (N : Node_Id); -- The node N is an attribute reference node for the Valid attribute where -- the prefix is of a Vax floating-point type. This procedure expands the -- necessary call for the validity test. end Exp_VFpt;
