Bill Wendling c83693f5b0 N.B. This is with the new EH scheme: The blocks with invokes have branches to the dispatch block, because that more correctly models the behavior of the CFG. The dispatch of course has edges to the landing pads. Those landing pads could contain invokes, which then have branches back to the dispatch. This creates a loop. The machine LICM pass looks at this loop and thinks it can hoist elements out of it. But because the dispatch is an alternate entry point into the program, the hoisted instructions won't be executed. I wasn't able to get a testcase which was small and could reproduce all of the time. The function_try_block.cpp in llvm-test was where this showed up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141726 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-11 22:42:31 +00:00
