llvm dev - Nov 2014 - [LLVMdev] Optimization of landing pads

Hi,
I am seeing that LLVM optimizer often inlines functions called from landing
pads.
- Is this expected?   I thought that landing pads were always considered to
be on the "cold" path...
- Is there any way to discourage inlining in landing pads and optimize them
for size?

thanks!

We already have a heuristic that unwind edges are infrequently taken, but
it sounds like the inliner isn't taking this into account. Maybe the new
pass manager can fix this, given that it's supposed to enable access to
branch profiles.
