Cleaning up LLVM IR mode for Emacs.
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:
