64 Bit Intel-Processors??

Thomas Zastrow
Hello,

I'm writing a little article about Pascal-Development under Linux. My
question: Am I right that FPC will not work on Intels
64-Bit-Processors??? I just found something about the
AMD-64-Bit-platform ...

Greetings,

Tom

I don't expect problems. Maybe you should be more clear about what you "found".

It should run on Intel EM64T (http://en.wikipedia.org/wiki/EM64T)
processors (that means the latest Pentium 4 and Xeon processors),
although I haven't tested it on Intel - I have an Athlon 64. It won't
work on IA-64 (http://en.wikipedia.org/wiki/IA-64) processors like the
Itanium.

OK, I just found on the FPC-Website: " ... It is available for different
processors: Intel x86, Amd64/x86 64, PowerPC, Sparc..."

So I was not sure if it runs on *Intel* - 64-Bit (I'm not a
hardware-specialist, but it isn't sooo important for my text, I just
don't want to write anything wrong.)

Greetings,

Tom

AMD originally invented the 64-bit extensions to the x86 chipset, Intel
licensed them later. Before Intel licensed it, the arch was named AMD64,
after Intel also started pushing out AMD64's it is called x86_64.

So Intel x86_64's will work. Itaniums will not, but these are hard (and
expensive) to come by.
