* Try to keep the cached inliner costs around for a bit longer for big functions.Jakob Stoklund Olesen2010-03-091-0/+3
| | | | | | | | | | | | | | | The Caller cost info would be reset everytime a callee was inlined. If the caller has lots of calls and there is some mutual recursion going on, the caller cost info could be calculated many times. This patch reduces inliner runtime from 240s to 0.5s for a function with 20000 small function calls. This is a more conservative version of r98089 that doesn't break the clang test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining for constant folding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98099 91177308-0d34-0410-b5e6-96231b3b80d8
