Subject: Improvements to emacs packages for llvm and tablegen mode.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=1763c0ad7f5cfb773213c39261f5664683219c3e;p=oota-llvm.git

Improvements to emacs packages for llvm and tablegen mode.

* Both files have valid package headers and footers (you can verify
with M-x checkdoc).
* Fixed style warnings generated by checkdoc.
* Fixed a byte-compiler warning in llvm-mode.el.
* Ensure that the modes are autoloaded, so users do not need to
(require 'llvm-mode) to use them.

Patch by Wilfred Hughes.
