From d681e31b46bdfad5bcc925241472c272f9796aa5 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Wed, 18 Jun 2014 19:05:24 +0000 Subject: Change IRObjectFile to parse the bitcode lazily. The main point of this class is to provide a cheap object interface to a bitcode file, so it has to be as lazy as possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211207 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Object/IRObjectFile.cpp | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'lib/Object') diff --git a/lib/Object/IRObjectFile.cpp b/lib/Object/IRObjectFile.cpp index 48820361d4..004d8de065 100644 --- a/lib/Object/IRObjectFile.cpp +++ b/lib/Object/IRObjectFile.cpp @@ -23,7 +23,8 @@ using namespace object; IRObjectFile::IRObjectFile(MemoryBuffer *Object, std::error_code &EC, LLVMContext &Context, bool BufferOwned) : SymbolicFile(Binary::ID_IR, Object, BufferOwned) { - ErrorOr MOrErr = parseBitcodeFile(Object, Context); + ErrorOr MOrErr = + getLazyBitcodeModule(Object, Context, /*BufferOwned*/ false); if ((EC = MOrErr.getError())) return; @@ -104,11 +105,21 @@ std::error_code IRObjectFile::printSymbolName(raw_ostream &OS, return object_error::success; } +static bool isDeclaration(const GlobalValue &V) { + if (V.hasAvailableExternallyLinkage()) + return true; + + if (V.isMaterializable()) + return false; + + return V.isDeclaration(); +} + uint32_t IRObjectFile::getSymbolFlags(DataRefImpl Symb) const { const GlobalValue &GV = getGV(Symb); uint32_t Res = BasicSymbolRef::SF_None; - if (GV.isDeclaration() || GV.hasAvailableExternallyLinkage()) + if (isDeclaration(GV)) Res |= BasicSymbolRef::SF_Undefined; if (GV.hasPrivateLinkage()) Res |= BasicSymbolRef::SF_FormatSpecific; -- cgit v1.2.3
