Patch for the patch
The attached patch seems to fix the problem.
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?
