Don't fetch pointers from a InMemoryStruct. InMemoryStruct is extremely dangerous as it returns data from an internal buffer when the endiannes doesn't match.

Add a function 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 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 :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170838 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a memory leak in MachOObjectFile. MachOObjectFile owns a MachOObj, but never frees it. Both MachOObjectFile and MachOObj want to own the MemoryBuffer, though, so we have to be careful and give them each one of their own.

Add support for the notion of "hidden" relocations. On MachO, these are relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves. I'm not familiar enough with ELF or COFF to know if they should have any relocations marked hidden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142961 91177308-0d34-0410-b5e6-96231b3b80d8

[Object] * Add begin_dynamic_table() / end_dynamic_table() private interface to ELFObjectFile. * Add begin_libraries_needed() / end_libraries_needed() interface to ObjectFile, for grabbing the list of needed libraries for a shared object or dynamic executable. * Implement this new interface completely for ELF, leave stubs for COFF and MachO. * Add 'llvm-readobj' tool for dumping ObjectFile information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151785 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a memory leak in MachOObjectFile. MachOObjectFile owns a MachOObj, but never frees it. Both MachOObjectFile and MachOObj want to own the MemoryBuffer, though, so we have to be careful and give them each one of their own. Thanks to Greg Clayton, Eric Christopher and Michael Spencer for helping figure out what's going wrong here. rdar://12561773 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168923 91177308-0d34-0410-b5e6-96231b3b80d8
