From b21ab43cfc3fa0dacf5c95f04e58b6d804b59a16 Mon Sep 17 00:00:00 2001 From: Alexey Samsonov Date: Mon, 18 Nov 2013 09:31:53 +0000 Subject: Revert r194865 and r194874. This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/MCTargetDesc/PPCMCTargetDesc.cpp | 3 --- lib/Target/PowerPC/PPCInstrInfo.cpp | 5 +---- lib/Target/PowerPC/PPCInstrInfo.h | 1 - lib/Target/PowerPC/PPCTargetStreamer.h | 1 - 4 files changed, 1 insertion(+), 9 deletions(-) (limited to 'lib/Target/PowerPC') diff --git a/lib/Target/PowerPC/MCTargetDesc/PPCMCTargetDesc.cpp b/lib/Target/PowerPC/MCTargetDesc/PPCMCTargetDesc.cpp index 8f4e224219..5c08de1ccf 100644 --- a/lib/Target/PowerPC/MCTargetDesc/PPCMCTargetDesc.cpp +++ b/lib/Target/PowerPC/MCTargetDesc/PPCMCTargetDesc.cpp @@ -37,9 +37,6 @@ using namespace llvm; -// pin vtable to this file -PPCTargetStreamer::~PPCTargetStreamer() {} - static MCInstrInfo *createPPCMCInstrInfo() { MCInstrInfo *X = new MCInstrInfo(); InitPPCMCInstrInfo(X); diff --git a/lib/Target/PowerPC/PPCInstrInfo.cpp b/lib/Target/PowerPC/PPCInstrInfo.cpp index 102057193e..375daee59e 100644 --- a/lib/Target/PowerPC/PPCInstrInfo.cpp +++ b/lib/Target/PowerPC/PPCInstrInfo.cpp @@ -33,7 +33,7 @@ #include "llvm/Support/raw_ostream.h" #define GET_INSTRMAP_INFO -#define GET_INSTRINFO_CTOR_DTOR +#define GET_INSTRINFO_CTOR #include "PPCGenInstrInfo.inc" using namespace llvm; @@ -45,9 +45,6 @@ opt DisableCTRLoopAnal("disable-ppc-ctrloop-analysis", cl::Hidden, static cl::opt DisableCmpOpt("disable-ppc-cmp-opt", cl::desc("Disable compare instruction optimization"), cl::Hidden); -//pin vtable to this file -void PPCInstrInfo::anchor() {} - PPCInstrInfo::PPCInstrInfo(PPCTargetMachine &tm) : PPCGenInstrInfo(PPC::ADJCALLSTACKDOWN, PPC::ADJCALLSTACKUP), TM(tm), RI(*TM.getSubtargetImpl()) {} diff --git a/lib/Target/PowerPC/PPCInstrInfo.h b/lib/Target/PowerPC/PPCInstrInfo.h index f140c41a2a..bd72a4d9e5 100644 --- a/lib/Target/PowerPC/PPCInstrInfo.h +++ b/lib/Target/PowerPC/PPCInstrInfo.h @@ -78,7 +78,6 @@ class PPCInstrInfo : public PPCGenInstrInfo { const TargetRegisterClass *RC, SmallVectorImpl &NewMIs, bool &NonRI, bool &SpillsVRS) const; - virtual void anchor(); public: explicit PPCInstrInfo(PPCTargetMachine &TM); diff --git a/lib/Target/PowerPC/PPCTargetStreamer.h b/lib/Target/PowerPC/PPCTargetStreamer.h index e876be16a9..3ecd8a8b0a 100644 --- a/lib/Target/PowerPC/PPCTargetStreamer.h +++ b/lib/Target/PowerPC/PPCTargetStreamer.h @@ -15,7 +15,6 @@ namespace llvm { class PPCTargetStreamer : public MCTargetStreamer { public: - virtual ~PPCTargetStreamer(); virtual void emitTCEntry(const MCSymbol &S) = 0; }; } -- cgit v1.2.3
