Comment (by altaic):

 Replying to [comment:20 dterei]:

 > The other issue is that fixing TNTC doesn't eliminate the mangler. We
 use it for a few different reasons now. I can think of at least 3 I
 believe: TNTC, SIMD, and Windows.

 I didn't know the mangler is used for Windows, though I recall it was
 (is?) used for stack alignment on OSX.

 I was hoping that a move to using the LLVM API would allow enough control
 to be rid of the mangler once and for all, but it seems the idea is not
 getting much traction. I may press on in my own tree to gather some stats
 and become more familiar with LLVM's internals. Maybe it'll bear some
 unexpected fruit.

 Cheers,
 Will
