[PATCH] Emit the ARM build attributes ABI_PCS_wchar_t and ABI_enum_size.

[Renato Golin]

Hi Oliver,

I'm happy with this patch, but we need to make sure we don't create those attributes on other architectures in D4212.

We can overlook the non use of the extra options (as you said, following current implementation), but as it stands, it's not just unused, but impossible to use from a language point of view. That's why I proposed a textual format (for the ABI type), but this can be done later. Please add a FIXME to that regard.

cheers,
