GCC (C,C++) and CSiBE set compiles with it. Now doing the full testsuite... Kaz, if you have some time, could you try it out in your setup, too please? A thing that bugs me regarding the attached patch is the big/little endian subreg copy pasta in the patterns *negnegt, *movtt, *movt_qi. Isn't there a way to avoid that?
