James Molloy d523d136d2 [InlineCost] Reduce inline thresholds to compensate for cost changes ... In r286814, the algorithm for calculating inline costs changed. This caused more inlining to take place which is especially apparent in optsize and minsize modes. As the cost calculation removed a skewed behaviour (we were inconsistent about the cost of calls) it isn't possible to update the thresholds to get exactly the same behaviour as before. However, this threshold change accounts for the very common case where an inline candidate has no calls within it. In this case, r286814 would inline around 5-6 more (IR) instructions. The changes to -Oz have been heavily benchmarked. The "obvious" value for the inline threshold at -Oz is zero, but due to inaccuracies in the inline heuristics this can actually cause code size increases due to not inlining key thunk functions (that then disappear). Experimentally, 5 was the sweet spot for code size over the test-suite. For -Os, this change removes the outlier results shown up by green dragon (http://104.154.54.203/db_default/v4/nts/13248). Fixes D26848. llvm-svn: 288024		2016-11-28 11:07:37 +00:00
