I'm pretty sure the arithmetic operators are supposed to stay transparent for both overflow analysis and debug info. I'm not sure why you'd see a difference between _transparent and inline(__always) either.

@jrose-apple early inlining, more convoluted code, less optimization? I don't honestly know. But evidence is that it helps. As for the overflow diagnostics, there are tests that should show if we regress.

IIRC some of the overflow diagnostic tests were already broken by other work you all did last year; have those been restored yet?

If removing @_transparent really saves a significant amount of binary size, can we make transparent things always-emit-into-client? The symbols ought to be rarely needed in practice since they'll almost always be inlined.

Looks like only one debug info test failed; we should probably have more. You really can't remove _transparent here; this is what it was made for.

[moiseev]

The problem is not with transparent per se. It’s saving some space in the implementation of `DoubleWidth`. But it’s not enough. So I’ll just leave it as is, until we have a better solution. And no, those overflow diagnostics tests have not been fixed, and I am very aware of that =(

If removing @_transparent really saves a significant amount of binary size, can we make transparent things always-emit-into-client? The symbols ought to be rarely needed in practice since they'll almost always be inlined. — You are receiving this because you authored the thread.
