New issue 2165: Default branch arm backend translation fails (unknown asm registers)
https://bitbucket.org/pypy/pypy/issues/2165/default-branch-arm-backend-translation

Pete Vine:

Trying to translate the latest default branch of pypy natively on an armv7 linux platform using gcc 4.9.2 and pypy 2.6.1,

 `PYPY_GC_MAX_DELTA=200MB pypy --jit loop_longevity=300 ../../rpython/bin/rpython --source -Ojit --jit-backend=arm targetpypystandalone`

 fails with:

```
