Re: major mode for mips assembly

[Lars Kristiansson]

Hi!

I don't know if this helps very much, maybe this is something You have
already. I have merged my lisp-files from the Emacs20.7 shipment with my
lisp-files from the University, so I don't know if it's new or not. Moreover I
don't know if it is complete. It's running in my Emacs anyway. Tell me if any
file is missing, and I'll look again.

Here they are anyway. They are located in Emacs20.7/progmodes. Do a recompile
of it for security.

This worked fine when I attended a course using MipsPRO Assembler. I felt
content with it. Anyway it's a start.

;;; Commentary:

;; This mode was written by Eric S. Raymond <esr@snark.thyrsus.com>,
;; inspired by an earlier asm-mode by Martin Neitzel.

;; This minor mode is based on text mode.  It defines a private abbrev table
;; that can be used to save abbrevs for assembler mnemonics.  It binds just
;; five keys:
;;
;;      TAB             tab to next tab stop
;;      :               outdent preceding label, tab to tab stop
;;      comment char    place or move comment
;;                      asm-comment-char specifies which character this is;
;;                      you can use a different character in different
;;                      Asm mode buffers.
;;      C-j, C-m        newline and tab to tab stop
;;
;; Code is indented to the first tab stop level.

;; This mode runs two hooks:
;;   1) An asm-mode-set-comment-hook before the part of the initialization
;; depending on asm-comment-char, and
;;   2) an asm-mode-hook at the end of initialization.
