Hi, saw this thread from a few days ago and wanted to clarify:

It looks like your changes wrt __native_client_codegen__ are good, though I
didn't look at them in fine detail or compile it. The main thing here is
that __native_client_codegen__ asm output is going to target a completely
different toolchain than the standard mac toolchain. It's more similar to a
linux gcc/binutils toolchain.
Really the __native_client_codegen__ in AOT is a cross-compiler but we
didn't go through the motions of splitting out the arch specific files
because they're 99% similar to existing codegens. We also wanted to benefit
from future changes to the arch specific files. But we needed it to work on
Macs too so that's why we have this define sprinkled in around APPLE
