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/Assembly/PrintModulePass.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/llvm/Assembly') diff --git a/include/llvm/Assembly/PrintModulePass.h b/include/llvm/Assembly/PrintModulePass.h index fb4f6a7..239fbcc 100644 --- a/include/llvm/Assembly/PrintModulePass.h +++ b/include/llvm/Assembly/PrintModulePass.h @@ -27,7 +27,9 @@ namespace llvm { /// createPrintModulePass - Create and return a pass that writes the /// module to the specified raw_ostream. - ModulePass *createPrintModulePass(raw_ostream *OS, bool DeleteStream=false); + ModulePass *createPrintModulePass(raw_ostream *OS, + bool DeleteStream=false, + const std::string &Banner = ""); /// createPrintFunctionPass - Create and return a pass that prints /// functions to the specified raw_ostream as they are processed. -- cgit v1.1
