Yes, Richard Earnshaw ([EMAIL PROTECTED]) is working on a better better
ARM back-end for gcc. This is a quote from the gcc (formerly known as
egcs) mailing list:

Yes, we are developing a new arm+thumb combined back end on a branch. At
this time I'm not sure when this will get merged (hopefully not too long
now -- I mainly want to sort out a few issues I have with the latest
constant pool code). The problem is that both Nick and I have had other
things going on which are taking priority (in my case nothing to do with
gcc).
