I've made a range of improvements to the Emacs mode for LLVM IR. Most importantly, it changes llvm-mode to inherit from prog-mode. This means llvm-mode will be treated as a normal programming mode in Emacs, so many Emacs features will just work. prog-mode is new to Emacs 24, so I've added an alias to ensure compatibility with Emacs 23 too. I've changed the mode definition to use define-derived-mode. This saves us needing to set up local variables ourselves, and saves us needing to define llvm-mode-map, llvm-mode-abbrev-table, llvm-mode-map. I've removed the keybindings to tab-to-tab-stop, center-line and center-paragraph. This shouldn't be llvm-mode's responsibility, and the code didn't actually work anyway (since `(not llvm-mode-map)` always evaluated to `t`, the keybindings were never executed). I've simplified the syntax-table definition, it's equivalent (e.g. `"` is treated as string delimiter by default in Emacs). I've added `.` as a symbol constituent, so functions like `llvm.memset.p0i8.i32` are recognised as a single symbol. I've also changed `%` to be a symbol constituent, so users can move between words or symbols at their choice, rather than conflating the two. I've fixed regexp for types, which incorrect used `symbol` instead of `symbols` as an argument to `regexp-opt`. This was causing incorrect highlighting on lines like `call void @foovoid`. I've removed string and comment highlighting from `llvm-font-lock-keywords`. This is already handled by the syntax-table. Finally, I've removed the reference to jasmin. That project is long abandoned and the link 404s. For reference, I've found an old copy of the project here: https://github.com/stevej/emacs/blob/master/vendor/jasmin/jasmin.el Patch by Wilfred Hughes! llvm-svn: 247281 |

README
-*- llvm/utils/emacs/README -*-
These are syntax highlighting files for the Emacs and XEmacs editors. Included
are:
* llvm-mode.el
Syntax highlighting mode for LLVM assembly files. To use, add this code to
your ~/.emacs :
(setq load-path
(cons (expand-file-name "path-to-llvm/utils/emacs") load-path))
(require 'llvm-mode)
* tablegen-mode.el
Syntax highlighting mode for TableGen description files. To use, add this code
to your ~/.emacs:
(setq load-path
(cons (expand-file-name "path-to-llvm/utils/emacs") load-path))
(require 'tablegen-mode)
Note: If you notice missing or incorrect syntax highlighting, please contact
<llvm-bugs [at] lists.llvm.org>; if you wish to provide a patch to improve the
functionality, it will be most appreciated. Thank you.
