Description Nurdin Premji 2007-08-03 21:52:56 UTC 
according to www.linux-foundation.org/spec/refspecs/elf/x86_64-SysV-psABI.pdf
the registers should be in the order rax, rbx, rcx, rdx, gcc puts them in rax,
rdx, rcx, rbx.

Turns out that www.linux-foundation.org/spec/refspecs/elf/x86_64-SysV-psABI.pdf
is obsolete and reference should be made to:
