From d218c261247edb8b44132fcff3588a67494effb6 Mon Sep 17 00:00:00 2001 From: Zachary Turner Date: Fri, 22 Jul 2016 15:46:37 +0000 Subject: [pdb] Round-trip module & file info to/from YAML. This implements support for writing compiland and compiland source file info to a binary PDB. This is tested by adding support for dumping these fields from an existing PDB to yaml, reading them back in, and dumping them again and verifying the values are as expected. llvm-svn: 276426 --- llvm/lib/DebugInfo/PDB/Raw/ModInfo.cpp | 49 ---------------------------------- 1 file changed, 49 deletions(-) (limited to 'llvm/lib/DebugInfo/PDB/Raw/ModInfo.cpp') diff --git a/llvm/lib/DebugInfo/PDB/Raw/ModInfo.cpp b/llvm/lib/DebugInfo/PDB/Raw/ModInfo.cpp index bae135f..538fe22 100644 --- a/llvm/lib/DebugInfo/PDB/Raw/ModInfo.cpp +++ b/llvm/lib/DebugInfo/PDB/Raw/ModInfo.cpp @@ -17,55 +17,6 @@ using namespace llvm; using namespace llvm::pdb; using namespace llvm::support; -namespace { - -struct SCBytes { - ulittle16_t Section; - char Padding1[2]; - little32_t Offset; - little32_t Size; - ulittle32_t Characteristics; - ulittle16_t ModuleIndex; - char Padding2[2]; - ulittle32_t DataCrc; - ulittle32_t RelocCrc; -}; - -// struct Flags { -// uint16_t fWritten : 1; // True if ModInfo is dirty -// uint16_t fECEnabled : 1; // Is EC symbolic info present?
