Hi everybody, I would like to use ruby2ruby in a caming project, but there seems to be an incompatibility with camping, ruby2ruby and markaby. Unfortunately I receive strange Markaby::InvalidXhtmlErrors. To demonstrate, that only combination of all three components causes the problem I added the following code. I relies on Markaby and ruby2ruby only and works fine (a.k.a. as expected).

...st a curiosity: does your changes have any impact on the compilation time? E.g, did you try comparing the old version with the modified version using llc -time-passes? best, Fernando > > Ok.

...operties (i.e., > they don't require an interference graph). I'm definitely interested in improving coalescing and it sounds like this would fall under that work.
