[llvm-dev] LTO and Inlining and Stack Frame Size

[Teresa Johnson via llvm-dev]

This is probably better controlled in the inliner, and there are internal
options there already for controlling various size thresholds. LTO doesn't
directly control inlining directly, it just provides a bigger
scope. +Easwaran who works on the inliner and might be able to point you in
the right direction.
