From e2c6d131d12c779a410740e0a90545def75e0f48 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Sat, 14 Aug 2010 00:29:42 +0000 Subject: Teach SimplifyCFG how to simplify indirectbr instructions. - Eliminate redundant successors. - Convert an indirectbr with one successor into a direct branch. Also, generalize SimplifyCFG to be able to be run on a function entry block. It knows quite a few simplifications which are applicable to the entry block, and it only needs a few checks to avoid trouble with the entry block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111060 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Transforms/Utils/Local.h | 2 -- 1 file changed, 2 deletions(-) (limited to 'include/llvm') diff --git a/include/llvm/Transforms/Utils/Local.h b/include/llvm/Transforms/Utils/Local.h index b277970727..caae27f47a 100644 --- a/include/llvm/Transforms/Utils/Local.h +++ b/include/llvm/Transforms/Utils/Local.h @@ -118,8 +118,6 @@ bool EliminateDuplicatePHINodes(BasicBlock *BB); /// of the CFG.
