Chandler Carruth f8cde7388e Cache the sized-ness of struct types, once we reach the steady state of ... "is sized". This prevents every query to isSized() from recursing over every sub-type of a struct type. This could get *very* slow for extremely deep nesting of structs, as in 177.mesa. This change is a 45% speedup for 'opt -O2' of 177.mesa.linked.bc, and likely a significant speedup for other cases as well. It even impacts -O0 cases because so many part of the code try to check whether a type is sized. Thanks for the review from Nick Lewycky and Benjamin Kramer on IRC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152197 91177308-0d34-0410-b5e6-96231b3b80d8		2012-03-07 02:33:09 +00:00

Function.h	Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.)
