2012-11-28Add back support for reading and parsing 'deplibs'.Bill Wendling
This is for backwards compatibility for pre-3.x bc files. The code reads the code, but does nothing with it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168779 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-27Modifying lli to use the SectionMemoryManager.Andrew Kaylor
The functionality of SectionMemoryManager is equivalent to the LLIMCJITMemoryManager being replaced except that it allocates memory as RW and later changes it to RX or R as needed. The page permissions are set in the call to MCJIT::finalizeObject. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168722 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-24libLTO: Add a utility method to initialize the disassemblers.Benjamin Kramer
Necessary to give disassembler users (like darwin's otool) a possibility to dlopen libLTO and still initialize the required LLVM bits. This used to go through libMCDisassembler but that's a gross layering violation, the MC layer can't pull in functions from the targets. Adding a function to libLTO is a bit of a hack but not worse than exposing other disassembler bits from libLTO. Fixes PR14362. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168545 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-23Add a -disable-cfi option to llvm-mc. This is useful for debugging asRafael Espindola
it will expand any .cfi_* directives in the input assembly. Unfortunately this cannot replace elf-dump in tests as the asm streamer cannot relax the line advance opcodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168522 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-05Add a method to indicate section address re-assignment is finished.Andrew Kaylor
Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8

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
