> That's pretty crazy assembly syntax... It looks like "AX" actually references "EAX" (in 32bit mode) and "RAX" (in 64bit mode), so neither Intel nor AT&T syntax.

Yeah it's plan9 assembly which is its own thing (just as plan9 "C" was its own thing): http://plan9.bell-labs.com/sys/doc/asm.html

AX, is just the lower 16 bits of EAX, so all correct. This is GAS / AT&T syntax

From the context it's obvious that 0x0 is right. AX must be 32 bits (or 64 bits) wide.

It's actually Go assembly, which (while being most similar to plan9 assembly) is also its own thing: https://golang.org/doc/asm
