[PATCH] D20708: Add ARM subtarget feature +long64

[Tim Northover via llvm-commits]

t.p.northover added a comment.

The only thing I know of that "long" could affect is the libcalls we produce, but as far as I'm aware the only dodgy cases are specified in terms of size_t and ptrdiff_t.

Those types vary completely independently of "long" (on some platforms they're "long", on others "long long").
