[fpc-pascal] IFDEF usage in x86_64's SwapEndian() implementation

Wed, 30 Mar 2016 02:10:19 -0700 

Hi,

Here is the x86_64's SwapEndian() function implementation.

=============[ src/rtl/x86_64/x86_64.inc ]====================
function SwapEndian(const AValue: DWord): DWord; assembler; nostackframe;
asm
{$ifdef win64}
  movl %ecx, %eax
{$else win64}
  movl %edi, %eax
{$endif win64}
  bswap %eax
end;
=============================================

Surely the usage of IFDEF WIN64 is not 100% correct or accurate. Should
the above not rather read IFDEF CPU64?

Regards,
  - Graeme -
