From 4ec3ae78b348ce963dc4f5a02e32c9b983da302b Mon Sep 17 00:00:00 2001 From: Anton Korobeynikov Date: Wed, 23 Jan 2013 15:03:08 +0000 Subject: [PATCH] Make sure metarenamer won't rename special stuff (intrinsics and explicitly renamed stuff). Otherwise this might hide the problems. llvm-svn: 173265 --- llvm/lib/Transforms/Utils/MetaRenamer.cpp | 20 +++++++++++++++++--- 1 file changed, 17 insertions(+), 3 deletions(-) diff --git a/llvm/lib/Transforms/Utils/MetaRenamer.cpp b/llvm/lib/Transforms/Utils/MetaRenamer.cpp index d519fb7..3716f58 100644 --- a/llvm/lib/Transforms/Utils/MetaRenamer.cpp +++ b/llvm/lib/Transforms/Utils/MetaRenamer.cpp @@ -72,13 +72,23 @@ namespace { // Rename all aliases for (Module::alias_iterator AI = M.alias_begin(), AE = M.alias_end(); - AI != AE; ++AI) - AI->setName("alias"); + AI != AE; ++AI) { + StringRef Name = AI->getName(); + if (Name.startswith("llvm.") || (!Name.empty() && Name[0] == 1)) + continue; + AI->setName("alias"); + } + // Rename all global variables for (Module::global_iterator GI = M.global_begin(), GE = M.global_end(); - GI != GE; ++GI) + GI != GE; ++GI) { + StringRef Name = GI->getName(); + if (Name.startswith("llvm.") || (!Name.empty() && Name[0] == 1)) + continue; + GI->setName("global"); + } // Rename all struct types TypeFinder StructTypes; @@ -95,6 +105,10 @@ namespace { // Rename all functions for (Module::iterator FI = M.begin(), FE = M.end(); FI != FE; ++FI) { + StringRef Name = FI->getName(); + if (Name.startswith("llvm.") || (!Name.empty() && Name[0] == 1)) + continue; + FI->setName(metaNames[prng.rand() % array_lengthof(metaNames)]); runOnFunction(*FI); } -- 2.7.4
