git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178994 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

2013-04-06Don't use InMemoryStruct<macho::SymtabLoadCommand>.Rafael Espindola
This also required not using the RegisterStringTable API, which is also a good thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178947 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-05Define versions of Section that are explicitly marked as little endian.Rafael Espindola
These should really be templated like ELF, but this is a start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178896 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-05Don't use InMemoryStruct in getSection and getSection64.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178894 91177308-0d34-0410-b5e6-96231b3b80d8
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
2013-02-28Move an assert earlier in a file and check that the result ofEric Christopher
our bitwise compare is equal to the field we're looking for. Noticed on inspection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176296 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Object: Fix errant fallthrough.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174079 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
2012-12-19Revert 170545 while I debug the ppc failures.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170547 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. The patch also changes MachOObjectFile::getSectionName to return just the section name instead of computing SegmentName,SectionName. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170545 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-13Revert "Add a funciton to get the segment name of a section."Eric Christopher
This reverts commit r170095 since it appears to be breaking the bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170105 91177308-0d34-0410-b5e6-96231b3b80d8

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

2012-11-29Fix a memory leak in MachOObjectFile.Jim Grosbach
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
