From 434bd8551d71384648f2e155d76b5ddbc4d1b258 Mon Sep 17 00:00:00 2001 From: David Greene Date: Fri, 2 Apr 2010 18:46:26 +0000 Subject: Let's try this again. Re-apply 100143 including an apparent missing include. For some reason the buildbot choked on this while my builds did not. It's probably due to a difference in system headers. --- Add some switches helpful for debugging: -print-before= Dump IR before running pass . -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@100204 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/MachineFunctionPass.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/llvm/CodeGen/MachineFunctionPass.h') diff --git a/include/llvm/CodeGen/MachineFunctionPass.h b/include/llvm/CodeGen/MachineFunctionPass.h index bac1103..1a2b129 100644 --- a/include/llvm/CodeGen/MachineFunctionPass.h +++ b/include/llvm/CodeGen/MachineFunctionPass.h @@ -34,6 +34,9 @@ protected: explicit MachineFunctionPass(intptr_t ID) : FunctionPass(ID) {} explicit MachineFunctionPass(void *ID) : FunctionPass(ID) {} + /// createPrinterPass - Get a machine function printer pass. + Pass *createPrinterPass(raw_ostream &O, const std::string &Banner) const; + /// runOnMachineFunction - This method must be overloaded to perform the /// desired machine code transformation or analysis. /// -- cgit v1.1
