The instruction and keyword lists are from NASM 2.12.01. Why?
I know not much has changed. But why maintain an outdated syntax?
The new file paths that contain the keywords used by nasm are these:
nasm/x86/insns.dat -> Instructions
nasm/x86/regs.dat -> Registers
nasm/asm/directiv.dat -> Directives
nasm/asm/pptok.dat -> Tokens 1.0?
nasm/asm/tokens.dat -> Tokens 2.0?
