No, that is currency. Comp is a plain 64 bit integer. It originally
comes from Turbo Pascal, which did not have a regular 64 bit integer
type. The x87 fpu can be used to perform 64 bit integer math though, so
it was originally a 64 bit integer typ

If all you want is colors and simple positioning, you could use Ansi escape
codes instead of the CRT unit, then you would not have the issue with
redirection and CRT not being supported. Windows 10 builds after 10586 have
re-enabled Ansi escape codes, however after build 14393 it is no longer

Correction: They were not added as of 3.0.4.rc1, they have been added now, not
sure exactly which version they are/were included.

AFAIK there is a small difference between comp and int64
COMP is 63bit + sign bit
int64 is 2s complement.
I hope I am right here.

Hello everyone,
I am getting an exception when I enable the -O2 optimization. More
precisaily, the line that stars with write_portd is corrupting the data
section. This is the pascal code:
function PciReadDword(const bus, device, func, regnum: UInt32): UInt32;
var
Send: DWORD;
begin

Thanks for the history. Comp has always puzzled me before, especially
with these two functions from the RTL
function MSecsToTimeStamp(MSecs: Comp): TTimeStamp;
function TimeStampToMSecs(const TimeStamp: TTimeStamp): comp;
I assume that these have come down from Turbo Pascal - but it still
seem
I think the problem was the way write_portd() is implemented:
procedure write_portd(const Data: Pointer; const Port: Word); {$IFDEF
ASMINLINE} inline; {$ENDIF}
asm // RCX: data, RDX: port
{$IFDEF LINUX} mov dx, port {$ENDIF}
mov rsi, data // DX=port
outsd
end;
If I replace with somethin

Hi Karol and thanks you very much! I got confused with the function names,
I feel very sorry.
As I said in my previous email, I fixed by rewriting the assembler
function. However, I don't why it worked.
So I understand you correctly, if I use assembler in my procedures there
could be a risk that I

By accident. Simply the register/stack/memo
Thank you very much Karol, I completly missed this point during the
development of my kernel (Or maybe I had in mind sometime ago but I forgot
it)
It was only when I decided to play with -02 that all these issues arrised.

No, it applies to *ALL* assembler code. Also inline blocks. The only
