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
2012-04-16Remove lto_codegen_set_whole_program_optimization. It is a work in progress,Rafael Espindola
so we don't want it to show up in the stable 3.1 interface. While at it, add a comment about why LTOCodeGenerator manually creates the internalize pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154807 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-04<rdar://problem/6940611> libLTO.dylib needs to let linker specify path to ↵Nick Kledzik
assembler Add lto_codegen_set_assembler_path() API which allows the linker to specify the path to the assembler tool to run.
