2013-08-26Revert LOCALMODs in gold plugin and libLTO related to bitcode shared objects ↵Derek Schuff
and symbol wrapping This reverts the local modifications to the gold plugin and liblto for bitcode shared objects and for symbol wrapping, neither of which are used or tested anymore. It depends on a corresponding change to the linker plugin API.

2013-08-07Revert localmod for bitcode linking speedup (different fix upstream).Jan Voung
Original localmod: https://codereview.chromium.org/10808021/ which fixes some quadratic behavior. 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

2012-12-04Sort the #include lines for tools/...Chandler Carruth
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

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.
2012-10-26libLTO has a bug in that it will keep every symbol if none is needed. We usedRafael Espindola
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

2012-08-13Change LLVM bitcode linking to use tree reductionJan Voung
rather than link in one at a time. Linking one at a time means that the "Dst" module keeps growing yet needs to be crawled entirely at each step to gather a set of types. http://codereview.chromium.org/10808021/
