[llvm-dev] Proposal for O1/Og Optimization and Code Generation Pipeline

[Cranmer, Joshua via llvm-dev]

A helpful intermediate for -Og would be to do the inlining anyways, but avoid actually deleting the now-unused functions.

This gives me some pause.  Many a time I've been in gdb, tried to execute a method and been told "sorry, can't find this, maybe it was inlined."

That said, inlining is absolutely crucial for any kind of performance with C++, so maybe this is an ok tradeoff.  Just wanted to raise the point.
