Add initial version of rtl.vim syntax file.

Hi.

This is equivalent of gimple.vim file. I'm aware of not full coverage of RTL
instructions, but hope it's a good start point.

I think this is nice to have and hope you'll get an OK for both this and
the gimple.vim patch.

One nit-pick: unlike "GIMPLE", "RTL" is not a GCC-specific abbreviation.
I'd prefer to use gcc-rtl.vim to avoid possible clashes.

Do you use it quite literally as described in gimple.vim, i.e. with
editing ftdetect.vim by hand? I made a plugin for gcc/match.pd syntax
highlighting, and I opted to use a common plugin file layout for it.
That way, I only need to symlink the plugin directory under .vim/bundle.

Thanks.

Hi.

Well, it's sitting in contrib, thus I'm planning to install that eventually
if there will be not response.

Good idea, let me fix that.

I use it as follows:

vimrc:

au BufRead,BufNewFile *.[0-2][0-9][0-9][ti].* set filetype=gimple
au BufRead,BufNewFile *.[2-3][0-9][0-9]r.* set filetype=rtl

Then I copied these .vim files into syntax folder. I know it's not ideal.
For all other vim extensions I use plugin system (Dein) that installs plugins
from github repos.

So you prefer to come up with a plugin folder with the *.vim files?

Thanks,
Martin

Yes, the main reason being very simple installation if already using a
plugin manager. A plugin folder may contain a custom ftdetect/foo.vim,
so there's no need to edit .vimrc by hand.

If you prefer I can post patches to that effect after yours are applied.

That would be great.

Whatever works best in terms of ease of use for someone that wants to
use the RTL (or gimple) modes.  If that means they need to be in a
subdir, that's fine with me.

Hi.

This is final version I'm going to install. Updates since last version:
- RTL modes added
- rtlInstruction should cover most of instructions we have (done via grepping
of DEF_RTL_EXPR).
- renamed to gcc-rtl.vim
