sh-elf-4_1-branch created


I have created the sh-elf-4_1-branch and checked in the results from the merge of
SuperH and STM sh-specific patches. I have also checked in four target-independent
patches to fix latent bugs that caused regressions with the merge. These patches are
not essential at the moment to build sh-elf or sh64-elf, though, but I have included
them so that the port can be judged on its own merits rather than its interaction with
latent bugs that can be fixed with a few small patches. This is about 420 KBytes of
unidiff in total, so I suppose there is little point in posting the patch.
There are no new regressions for sh-elf in C, c++ or objc for SH1 or SH4 little endian.
There are a few new regressions for SH64, but overall there are still less regressions for
SH64 in C than without these patches.


Please test the branch on your SH targets, I hope to merge this into the 4.1 mainline in a
few days if there are no problems. If you are working on patches that overlap with my
changes, like the predicates reorganization it is probably best if you work in the branch.


I'll be working on reducing the regresion count further.

Check-in privileges are like on mainline, except that I might make more machine-indepent
changes to fix bugs, or merges from mainline.
