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. R=eliben@chromium.org, jvoung@chromium.org BUG= https://code.google.com/p/nativeclient/issues/detail?id=3520 Review URL: https://codereview.chromium.org/22831032
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

2012-12-10Revert r169656.Bill Wendling
The linker will call `lto_codegen_add_must_preserve_symbol' on all globals that should be kept around. The linker will pretend that a dylib is being created. <rdar://problem/12528059> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169770 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-08Add the `lto_codegen_set_export_dynamic' function.Bill Wendling
This function sets the `_exportDynamic' ivar. When that's set, we export all symbols (e.g. we don't run the internalize pass). This is equivalent to the `--export-dynamic' linker flag in GNU land: --export-dynamic When creating a dynamically linked executable, add all symbols to the dynamic symbol table. The dynamic symbol table is the set of symbols which are visible from dynamic objects at run time. If you do not use this option, the dynamic symbol table will normally contain only those symbols which are referenced by some dynamic object mentioned in the link. If you use dlopen to load a dynamic object which needs to refer back to the symbols defined by the program, rather than some other dynamic object, then you will probably need to use this option when linking the program itself. The Darwin linker will support this via the `-export_dynamic' flag. We should modify clang to support this via the `-rdynamic' flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169656 91177308-0d34-0410-b5e6-96231b3b80d8
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
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/

2012-04-16Remove lto_codegen_set_whole_program_optimization. It is a work in progress,Rafael Espindola
