| Summary | 0007179: Spurious warnings | ||||
| Description | FPC 2.1.1 generates spurious "type size mismatch" warnings for some arithmetic expressions. FPC 2.0.2 and Delphi 7 do not generate these warnings. Example: program TestMismatch; type TTestClass = class(TObject) public procedure AProc(AValue : Single); end; procedure TTestClass.AProc(AValue : Single); begin WriteLn(AValue); end; var AnObj : TTestClass; ASingle : Single; begin AnObj := TTestClass.Create; ASingle := 1; AnObj.AProc(ASingle * 2); //Does not generate warning AnObj.AProc(ASingle * 2.0); //Generates warning with -Cr or -vh end. | ||||

FPC 2.1.1 generates a warning for each double/extended -> single conversion (and perhaps others as well). This is incorrect and should be fixed! |
|
|
Also, a type cast to single(...) is not accepted by the compiler, so there is no way to 'fix' these warnings. |
|
|
FPC now, just like Delphi, sets the precision of floating point constants to the smallest one required (so 2.0 is now also a single, and therefore no warning is generated anymore for this test program). To Frederik: explicit typecasting to single/double also works for me in FPC with the current 2.1.1. |
