[cfe-dev] Is ARC expected to work on ARM?

FWIW, the ARCMT tests are NOT runtime tests. "MT" stands for "migration tool", so they are rewriting tests. They may depend on the selected ObjC runtime, but I wouldn't expect them to pass on other non-Darwin 32-bit platforms and fail on ARM/Linux.

I'm not so familiar with the ARCMT tests, though.

(I presume if you want to be a brave ecosystem explorer you could also consider ARM/WINCE :-) ). Is there an expectation that ARC tests only use run-time functionality that should work on the ARM/Linux combination?
