fpc 3.1.1 on i386
-O3
function FOO: Boolean; inline;
begin
Result := FMem <> nil;
end;
function BAR: TPItemT;
begin
if FOO
then Result := nil
else Result := TPItemT(FMem.FirstItemPointer + (Index *
FItemSize.ItemSize));
end;
generates something like:
005EACF0 833A00 cmp dword ptr [edx],$00
005EACF3 0F95C0 setnz al
005EACF6 84C0 test al,al
005EACF8 7509 jnz +$09
Is that something that should be optimized away?
al represents the nz flag
test al,al restores the nz flag, to what it already is. hat seems pointless.
