The operation is apparently (judging from the 32-bit branch) designed to stuff the value of __op_PARAM1 (which is normally 32 bits but could be shorter or longer) into A0 (which is 64-bit on x86-64). I am not familiar with the __op_ token in asm and cannot find any information on it. Does anybody know what is happening here? Would it be unreasonable to allow the simple assignment if a long on the platform in question is the same size as the target register?

I think the problem might actually be the global register variables A0, A1, A2, T0, T1, T2. LLVM doesn’t like those. This is what clang complains about if you try to compile with it instead of LLVM-GCC, at least.

The easiest, if not the most satisfying, way to get BII/SS compiling on newer systems might be to get them to work with the various gcc ports available via MacPorts. I’ve been playing with that today, and getting sanity check errors in the configure script. Trying to figure out what’s going on there right now.
