hi,

Code Select Expand

how about 64bit? what are they?

rax, rbx, rcx, rdx, rsp, rbp, rsi, rdi
there also 8 new registers in x64: r8,r9 ... r15

just take a look in the amd(or intel) developer manuals:

http://developer.amd.com/documentation/guides/Pages/default.aspx#manuals

especial into: http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/24592.pdf
-> see chapter 3.1
