...would not survive. So the 'safepoint' metadata
*must* be preserved across optimizations if the instruction gets emitted.

[LLVMdev] Adding a custom GC safe point creation phase
Hi Chris, Gordon,
Here's a patch to allow a GCStrategy to customize the places where it wants
to insert safe points. I'm not sure who maintains the GC code today in LLVM
(I'd be happy to take ownership, if needed).
The patch just adds up a custom safepoints flag, similar to the way the
GCStrategy can customize intrinsics lowering, or roots initialization. It
works pretty well, as
