Hans Wennborg 89fa06ba0f Switch-to-lookup tables: set threshold to 3 cases ... There has been an old FIXME to find the right cut-off for when it's worth analyzing and potentially transforming a switch to a lookup table. The switches always have two or more cases. I could not measure any speed-up by transforming a switch with two cases. A switch with three cases gets a nice speed-up, and I couldn't measure any compile-time regression, so I think this is the right threshold. In a Clang self-host, this causes 480 new switches to be transformed, and reduces the final binary size with 8 KB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199294 91177308-0d34-0410-b5e6-96231b3b80d8		2014-01-15 05:00:27 +00:00

common-dest-folding.ll	FoldBranchToCommonDest merges branches into a single branch with or/and of the condition. It has a heuristics for estimating when some of the dependencies are processed by out-of-order processors. This patch adds another rule to the heuristics that says that if the "BonusInstruction" that we speculatively execute is used by the condition of the second branch then it is okay to hoist it. This change exposes more opportunities for other passes to transform the code. It does not matter that much that we if-convert the code because the selectiondag builder splits or/and branches into multiple branches when profitable.	2013-11-12 22:37:16 +00:00
