Consider http://goo.gl/qv5NKz * main() should inline to a call to puts and throwing an exception * There should be no unittest-related and no assert-related generated code in -release mode

With -O -release -inline: http://goo.gl/EYOHV1

I believe this would be the change in https://github.com/D-Programming-Language/dmd/pull/3552 As I understand it, the symbols are put on comdat, so would be emitted in compiles, but cleaned out in the link phase (or maybe post-strip).

The best thing DMD can do is to not rely on these artificial function helpers, and just inline whatever code it is they're emitting.

(In reply to Iain Buclaw from comment #3) > I believe this would be the change in > https://github.com/D-Programming-Language/dmd/pull/3552 I agree, and at least issue 13873 and issue 14044 are blocking the optimized objfile output.
