  For some reason (probably user error), "hg log -p -r xxxx:xxxx"
doesn't quite seem to get all the changes I made. The block you noticed
was fixed in the real code, but somehow missed the patch. Here's an
updated version:
http://www.senecass.com/projects/OpenJDK-ARM/thumb2-083110.patch

  The ARM assembler appears to be working, but there is still debugging
to do in thumb2.cpp before the thumb2 JIT fully works. I also merged in
a little patch from xerxes for pr484, which is currently untested.

  Which this patch, (and HOTSPOT_ASM enabled) test_gamma gets through
the first 56 tests like before, and then fails deep down in call_thumb2.
Tracking that down is the current debugging task.
