* Teach llvm-objdump with the -macho parser how to use the data in code tableKevin Enderby2013-06-061-6/+112
| | | | | | | | | | | | | | | from the LC_DATA_IN_CODE load command. And when disassembling print the data in code formatted for the kind of data it and not disassemble those bytes. I added the format specific functionality to the derived class MachOObjectFile since these tables only appears in Mach-O object files. This is my first attempt to modify the libObject stuff so if folks have better suggestions how to fit this in or suggestions on the implementation please let me know. rdar://11791371 llvm-svn: 183424
* Handle relocations that don't point to symbols.Rafael Espindola2013-06-051-3/+2
| | | | | | | | In ELF (as in MachO), not all relocations point to symbols. Represent this properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj ELF's dumper to handle relocatios without symbols. llvm-svn: 183284
* MC: Disassembled CFG reconstruction.Ahmed Bougacha2013-05-241-291/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch builds on some existing code to do CFG reconstruction from a disassembled binary: - MCModule represents the binary, and has a list of MCAtoms. - MCAtom represents either disassembled instructions (MCTextAtom), or contiguous data (MCDataAtom), and covers a specific range of addresses. - MCBasicBlock and MCFunction form the reconstructed CFG. An MCBB is backed by an MCTextAtom, and has the usual successors/predecessors. - MCObjectDisassembler creates a module from an ObjectFile using a disassembler. It first builds an atom for each section. It can also construct the CFG, and this splits the text atoms into basic blocks. MCModule and MCAtom were only sketched out; MCFunction and MCBB were implemented under the experimental "-cfg" llvm-objdump -macho option. This cleans them up for further use; llvm-objdump -d -cfg now generates graphviz files for each function found in the binary. In the future, MCObjectDisassembler may be the right place to do "intelligent" disassembly: for example, handling constant islands is just a matter of splitting the atom, using information that may be available in the ObjectFile. Also, better initial atom formation than just using sections is possible using symbols (and things like Mach-O's function_starts load command). This brings two minor regressions in llvm-objdump -macho -cfg: - The printing of a relocation's referenced symbol. - An annotation on loop BBs, i.e., which are their own successor. Relocation printing is replaced by the MCSymbolizer; the basic CFG annotation will be superseded by more related functionality. llvm-svn: 182628
* Remove the MachineMove class.Rafael Espindola2013-05-131-2/+3
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. llvm-svn: 181680
* Clarify getRelocationAddress x getRelocationOffset a bit.Rafael Espindola2013-04-251-1/+1
| | | | | | | | | | getRelocationAddress is for dynamic libraries and executables, getRelocationOffset for relocatable objects. Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a test of ELF's. llvm-readobj -r now prints the same values as readelf -r. llvm-svn: 180259
* Don't read one command past the end.Rafael Espindola2013-04-191-2/+6
| | | | | | | | | Thanks to Evgeniy Stepanov for reporting this. It might be a good idea to add a command iterator abstraction to MachO.h, but this fixes the bug for now. llvm-svn: 179848
* At Jim Grosbach's request detemplate Object/MachO.h.Rafael Espindola2013-04-181-26/+17
| | | | | | | We are still able to handle mixed endian objects by swapping one struct at a time. llvm-svn: 179778
* Finish templating MachObjectFile over endianness.Rafael Espindola2013-04-131-14/+34
| | | | | | | We are now able to handle big endian macho files in llvm-readobject. Thanks to David Fang for providing the object files. llvm-svn: 179440
* Simplify the code. No functionality change.Rafael Espindola2013-04-111-17/+1
| | | | llvm-svn: 179259
* Template the MachO types over endianness.Rafael Espindola2013-04-101-5/+6
| | | | | | For now they are still only used as little endian. llvm-svn: 179147
* Convert MachOObjectFile to a template.Rafael Espindola2013-04-091-4/+4
| | | | | | | For now it is templated only on being 64 or 32 bits. I will add little/big endian next. llvm-svn: 179097
* Implement MachOObjectFile::getHeader directly.Rafael Espindola2013-04-071-4/+4
| | | | llvm-svn: 178994
* Remove LoadCommandInfo now that we always have a pointer to the command.Rafael Espindola2013-04-071-3/+3
| | | | | | | LoadCommandInfo was needed to keep a command and its offset in the file. Now that we always have a pointer to the command, we don't need the offset. llvm-svn: 178991
* Add MachOObjectFile::LoadCommandInfo.Rafael Espindola2013-04-071-2/+2
| | | | | | This avoids using MachOObject::getLoadCommandInfo. llvm-svn: 178990
* Remove MachOObjectFile::getObject.Rafael Espindola2013-04-071-10/+8

* Don't fetch pointers from a InMemoryStruct.Rafael Espindola2013-04-051-3/+2
| | | | | | | | InMemoryStruct is extremely dangerous as it returns data from an internal buffer when the endiannes doesn't match. This should fix the tests on big endian hosts. llvm-svn: 178875
* Add a function to get the segment name of a section.Rafael Espindola2012-12-211-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On MachO, sections also have segment names. When a tool looking at a .o file prints a segment name, this is what they mean. In reality, a .o has only one anonymous, segment. This patch adds a MachO only function to fetch that segment name. I named it getSectionFinalSegmentName since the main use for the name seems to be inform the linker with segment this section should go to. The patch also changes MachOObjectFile::getSectionName to return just the section name instead of computing SegmentName,SectionName. The main difference from the previous patch is that it doesn't use InMemoryStruct. It is extremely dangerous: if the endians match it returns a pointer to the file buffer, if not, it returns a pointer to an internal buffer that is overwritten in the next API call. We should change all of this code to use support::detail::packed_endian_specific_integral like ELF, but since these functions only handle strings, they work with big and little endian machines as is. I have tested this by installing ubuntu 12.10 ppc on qemu, that is why it took so long :-) llvm-svn: 170838

* Add r170095 back.Rafael Espindola2012-12-191-1/+7
| | | | | | | | | | | | | | | | | | | | | | | I cannot reproduce it the failures locally, so I will keep an eye at the ppc bots. This patch does add the change to the "Disassembly of section" message, but that is not what was failing on the bots. Original message: Add a funciton to get the segment name of a section. On MachO, sections also have segment names. When a tool looking at a .o file prints a segment name, this is what they mean. In reality, a .o has only one anonymous, segment. This patch adds a MachO only function to fetch that segment name. I named it getSectionFinalSegmentName since the main use for the name seems to be infor the linker with segment this section should go to. The patch also changes MachOObjectFile::getSectionName to return just the section name instead of computing SegmentName,SectionName. llvm-svn: 170545

* Sort the #include lines for tools/...Chandler Carruth2012-12-041-3/+3
