Hi,
This handles NULL targetm.spill_class in assign_by_spills. This
showed up as a segfault during a build for arm-none-linux-gnueabi(hf).
Fix pre-approved by richi on IRC , verified that bootstrap continues
from where things broke further on a tree (that reverts 211600 which is
the next breakage causing commit on arm-none-linux-gnueabihf)
I'll apply this in about 45 minutes when I get back to my desk if no one
objects.
Ops, I've already committed the following patch (sorry I've not read
email before doing this):
I apologize for my mistake with the original patch.
