It depends on a corresponding change to the linker plugin API.

Xiaofei Wan fixed the quadratic behavior upstream differently, via a series of commits around: http://llvm.org/viewvc/llvm-project?view=revision&revision=181104 and it is actually faster: ~7 seconds to link pnacl-llc w/ just the upstream fix ~11 seconds to link with localmod (used to be ~120 seconds w/ quadratic behavior) BUG=http://code.google.com/p/nativeclient/issues/detail?id=2883 TEST= trybots: http://chromegw.corp.google.com/i/tryserver.nacl/builders/nacl-toolchain-linux-pnacl-x86_64/builds/784 R=eliben@chromium.org Review URL: https://codereview.chromium.org/22509002 2013-01-11T21:47:37Z Derek Schuff dschuff@chromium.org 2013-01-10T00:55:43Z urn:sha1:b770d0e0636a4b5ad61b1ca661caee67576c05fc deplib features commented out due to removal upstream; will add back as a localmod Conflicts: include/llvm/ADT/Triple.h include/llvm/MC/MCAssembler.h include/llvm/Target/TargetFrameLowering.h lib/CodeGen/AsmPrinter/DwarfDebug.cpp lib/CodeGen/AsmPrinter/DwarfDebug.h lib/CodeGen/BranchFolding.cpp lib/LLVMBuild.txt lib/Linker/LinkArchives.cpp lib/MC/MCAssembler.cpp lib/MC/MCELFStreamer.cpp lib/Makefile lib/Target/ARM/ARMExpandPseudoInsts.cpp lib/Target/ARM/ARMFrameLowering.cpp lib/Target/ARM/ARMISelLowering.cpp lib/Target/ARM/ARMSubtarget.h lib/Target/ARM/ARMTargetObjectFile.cpp lib/Target/ARM/MCTargetDesc/ARMAsmBackend.cpp lib/Target/Mips/MipsInstrFPU.td lib/Target/Mips/MipsInstrInfo.td lib/Target/X86/X86CodeEmitter.cpp lib/Target/X86/X86Subtarget.h lib/VMCore/Module.cpp test/MC/MachO/ARM/nop-armv4-padding.s tools/Makefile tools/llc/llc.cpp tools/lto/LTOModule.cpp tools/lto/lto.cpp 2012-12-04T10:44:52Z Chandler Carruth chandlerc@gmail.com 2012-12-04T10:44:52Z urn:sha1:f010c464a11444733ec67e31aace8bcebeaf2588 Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169252 91177308-0d34-0410-b5e6-96231b3b80d8 2012-11-06T18:23:47Z Derek Schuff dschuff@chromium.org 2012-11-06T18:23:47Z urn:sha1:5bcab54cfde18b4b11f163d7d916711df70cbebf Conflicts: lib/Target/ARM/ARMFrameLowering.cpp lib/Target/Mips/MipsRegisterInfo.cpp lib/Target/X86/X86ISelLowering.cpp lib/Transforms/IPO/ExtractGV.cpp tools/Makefile tools/gold/gold-plugin.cpp The only interesting conflict was X86ISelLowering.ccp, which meant I had to essentially revert r167104. The problem is that we are using ESP as the stack pointer in X86ISelLowering and RSP as the stack pointer in X86FrameLowering, and that revision made them both consistently use X86RegisterInfo to determine which to use. 2012-10-26T00:29:57Z Rafael Espindola rafael.espindola@gmail.com 2012-10-26T00:29:57Z urn:sha1:fffb72470d126e7000a03a88ed30326e3521d84f to hack around this in the gold plugin by deleting a module if no symbol was needed. Unfortunately, the hack is wrong in the case of o module having no visible symbols but still having side effects via static constructors. The bug will have to be fixed in libLTO itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166745 91177308-0d34-0410-b5e6-96231b3b80d8 2012-09-18T22:07:33Z Derek Schuff dschuff@chromium.org 2012-09-18T22:07:33Z urn:sha1:ef9bd62c68c2c279926e66058bc5a6ef62150432 Conflicts: include/llvm/CodeGen/ISDOpcodes.h include/llvm/Target/Target.td include/llvm/Target/TargetLowering.h include/llvm/Target/TargetOpcodes.h lib/Target/Mips/MCTargetDesc/MipsMCCodeEmitter.cpp lib/Target/Mips/MipsMCInstLower.cpp utils/TableGen/CodeGenTarget.cpp 2012-08-27T03:03:07Z Rafael Espindola rafael.espindola@gmail.com 2012-08-27T03:03:07Z urn:sha1:a16c2e3493816472afd78521094f08bf2d26165e --as-needed.
