There is a very old project, called mccp:

http://mcpp.sourceforge.net/

I'm afraid that's not active but may be useful. Eg. that has a
very good background documentation:

https://kumisystems.dl.sourceforge.net/project/mcpp/mcpp/V.2.7.2/mcpp-summary-272.pdf

Note that IMHO it doesn't use any LR or LALR parser, but I
didn't jumped into the source...

The another project - just found now - which could be interest
for you is this:

https://github.com/facebookarchive/warp

It was written in D, but there is a lexer, which can helps you.


Hope this helps.
