Ok, third time's the charm. No changes from last time except the CMake
source addition. Apparently the buildbots were wrong about failures. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass. These are helpful when tracking down a miscompilation. It is easy to get IR dumps and do diffs on them, etc. To make this work well, add a new getPrinterPass API to Pass so that each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass suitable for dumping out the kind of object the Pass works on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100249 91177308-0d34-0410-b5e6-96231b3b80d8
