* When encountering an unknown file format, ObjectFile::createObjectFile shouldEli Bendersky2013-01-251-1/+3

* [Object][ELF] Simplify ELFObjectFile by using ELFType.Michael J. Spencer2013-01-151-8/+8
| | | | | | | | | | | | | This simplifies the usage and implementation of ELFObjectFile by using ELFType to replace: <endianness target_endianness, std::size_t max_alignment, bool is64Bits> This does complicate the base ELF types as they must now use template template parameters to partially specialize for the 32 and 64bit cases. However these are only defined once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172515 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a function to get the segment name of a section.Rafael Espindola2012-12-211-14/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | 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.

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-033-5/+4
| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | 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.

* Refactor data-in-code annotations.Jim Grosbach2012-05-181-0/+13
| | | | | | | | | | | | | | | | | | | | | | Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 91177308-0d34-0410-b5e6-96231b3b80d8
