2013-04-19refactor the struct byte swapping to a helper function.Rafael Espindola

2013-04-19Don't read one command past the end.Rafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179848 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-18At Jim Grosbach's request detemplate Object/MachO.h.Rafael Espindola
We are still able to handle mixed endian objects by swapping one struct at a time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179778 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13Finish templating MachObjectFile over endianness.Rafael Espindola
We are now able to handle big endian macho files in llvm-readobject. Thanks to David Fang for providing the object files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179440 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-12Add 179294 back, but don't use bit fields so that it works on big endian hosts.Rafael Espindola
Original message: Print more information about relocations. With this patch llvm-readobj now prints if a relocation is pcrel, its length, if it is extern and if it is scattered. It also refactors the code a bit to use bit fields instead of shifts and masks all over the place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179345 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11Fix MachO's getRelocationAdditionalInfo.Rafael Espindola
It was returning the loaded address of the section containing the relocation, which really doesn't seem to be the intent of this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179255 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10Template the MachO types over endianness.Rafael Espindola
For now they are still only used as little endian. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179147 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-09Convert MachOObjectFile to a template.Rafael Espindola
For now it is templated only on being 64 or 32 bits. I will add little/big endian next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179097 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09Add a SymbolTableEntryBase.Rafael Espindola
Use it when we don't need to know if we have a 32 or 64 bit SymbolTableEntry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179074 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-08Add a SectionBase struct.Rafael Espindola
Use it to share code and when we don't need to know if we have a 32 or 64 bit Section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179072 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-07Implement MachOObjectFile::getHeaderSize and MachOObjectFile::getData.Rafael Espindola
These were the last missing forwarding functions. Also consistently use the forwarding functions instead of using MachOObj directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178992 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-07Remove LoadCommandInfo now that we always have a pointer to the command.Rafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178991 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-07Add MachOObjectFile::LoadCommandInfo.Rafael Espindola
This avoids using MachOObject::getLoadCommandInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178990 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-05Define versions of Section that are explicitly marked as little endian.Rafael Espindola

2013-04-05Don't fetch pointers from a InMemoryStruct.Rafael Espindola
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178875 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-21Add a function to get the segment name of a section.Rafael Espindola
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

2012-12-19Add r170095 back.Rafael Espindola
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.

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
