Hello Free Pascal community!
I'm pleased to announce the extension of TThread's interface to bring it
more on par with current Delphi versions.
Extensions:
Note: in the following list class means that the property or method is
a class property or method and thus can be called without a
Great! Keep up the good work ;-)
Rather funny actually... Quite some time ago I wrote my own threading
mechanism and decided to break compatibility with fpc's TThread
interface. Ever since I did that my own interface somehow became more
and more compatible again with the implementation of TThread

In our previous episode, Sven Barth said:
- ProcessorCount (class):
Returns the count of CPU cores detected by the RTL. This is based
on the new global property System.GetCPUCount which needs to be
implemented per target. Currently only a default implementation exists
which returns
Hmmm, that;s indeed quite some different output you've got there. Mine
looks like this:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Core(TM)2 Duo CPU E8600 @ 3.33GHz
stepping: 10
Right, since the /proc/cpuinfo (a) is not available on many platforms
and (b) has no standard output format, I decided to fix the half done
CPUID approach. Here it goes (note: don't shoot me if my assembly is a
bit weird, I've only learned part of it by experimenting):

It gives correct result (8 cores) on my Intel i7-3770K CPU with
HyperThreading enabled in the BIOS.
