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:
```
#!python
[platform:execute] gcc -c -O3 -pthread -fomit-frame-pointer -Wall -Wno-unused
-O3 -mcpu=cortex-a5
