Yesterday I discovered I wasn’t doing proper range checking for ordinal
constants so for example, a generic with “const U: byte” could be specialized
as <1000>. We want ordinal constants to respect range checks right?
I made a little utility function which works in most cases but I don’t think
it’s correct and more importantly this function probably already exists in the
compiler.
function compare_orddef_by_range(param1,param2:torddef): boolean;
var
orddef1,orddef2:tdef;
begin
range_to_type(param1.low,param1.high,orddef1);
range_to_type(param2.low,param2.high,orddef2);
result:=compare_defs(orddef1,orddef2,nothingn)>=te_convert_l1;
end;
Is there an existing function for this or a better way to do it?
Regards,
Ryan Joseph
