Is that possible with fpc?
If you know the register, just assign it via inline assembly.

Please disregard my previous statement abour renaming register names. I was
completely wrong. The problem most likely was with a wrong asm mode. Try to
specify the asm mode explicitly by adding
{$ASMMODE INTEL}
at the begging of the unit.
You might try an alternative version here: http://pastebin.

My situation is, I program and test on Ubuntu x64 on a i3-M390. Then
compile it to Windows 32bit on a VirtualBox on this
I am trying to use an external C++ dll and also privide call back
functions to this dll to call back.
However, the dll requires my functions to return 8 byte of 'struct' via
register and the dll author said it is not possible with Delphi.
Is that possible with fpc?

You're compiling for x64, You need to replace "eax" and "edx" with "rax"
and "rdx", since e?x are available for i386 only.

I ran it to test if it made a difference between cores and hyperthrea

FPC 2.7.1 has TThrea
I found this code on the net:
http://code.google.com/p/fpos/source/browse/kernel/cpuid.pas?r=c387b381d7a05f9328693cdcf59b0b4f633294e4
It's part of the "FreePascal Operationg System" project. I suppose it is
compatible with FreePascal of course. But while compiled, I got lots of
errors, such as:
If you're talking bout x88_64, i386 platforms, you should be able to do it
using CPUID instruction

Hi All,
Is there a platform independent (specifically Windows and Linux) way to
detect cores and hyper-threads of the CPU? I am writing a calculation
intensive app and would like to fully utilize SMP capability of the CPU.
Thanks!

I will check what these libraries can do and how fast.
