This is a complete rewrite of the highlighter using the new sublime-syntax format introduced with the recently released Sublime Text 3.

After update you'll see a new Nasm Assembly option in syntax list. Old x86 and x86_64 Assembly was left for ST2 users and backwards compatibility, it will be updated later (though it will never be as complete as this new one).

Highlights:

• Complete nasm syntax, following the 2.13.01 documentation
• Complete macro support, including all built-in functions and constants
• Directive-specific parameters and modifiers support where applicable
• A lot of fixes for labels, numerics, instruction prefixes, and everything else

• signed types (non-nasm)
• better support for various number notations (bin, oct, dec, hex, and packed bcd)
• better support for strings
• more built-in nasm functions for type convertion and constants

Fixed highlighting conflict for ah-dh registers with hex numbers

• Expanded NASM macro support
• Partial support for GAS comment style

Fixed some missing AMD instructions, including new Zen-specific ones

• Fixes for labels
  • More valid symbols are allowed now
  • Code and comments on the same line as label should be highlighted correctly now
• Fixes for sections
  • Comments on the same line
  • Added .rodata to known section names
• Support for binary, octal, and floating-point notations
