From 8ef3acba00c9c42d450fa52c7d3faebce1e507dd Mon Sep 17 00:00:00 2001 From: David Greene Date: Thu, 1 Apr 2010 22:43:57 +0000 Subject: 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@100143 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 bac110316d..1a2b12972a 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 v1.2.3-18-g5258
