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.

2012-12-16This patch is needed to make c++ exceptions work for mips16.Reed Kotler
Mips16 is really a processor decoding mode (ala thumb 1) and in the same program, mips16 and mips32 functions can exist and can call each other. If a jal type instruction encounters an address with the lower bit set, then the processor switches to mips16 mode (if it is not already in it). If the lower bit is not set, then it switches to mips32 mode. The linker knows which functions are mips16 and which are mips32. When relocation is performed on code labels, this lower order bit is set if the code label is a mips16 code label. In general this works just fine, however when creating exception handling tables and dwarf, there are cases where you don't want this lower order bit added in. This has been traditionally distinguished in gas assembly source by using a different syntax for the label. lab1: ; this will cause the lower order bit to be added lab2=. ; this will not cause the lower order bit to be added In some cases, it does not matter because in dwarf and debug tables the difference of two labels is used and in that case the lower order bits subtract each other out. To fix this, I have added to mcstreamer the notion of a debuglabel. The default is for label and debug label to be the same. So calling EmitLabel and EmitDebugLabel produce the same result. For various reasons, there is only one set of labels that needs to be modified for the mips exceptions to work. These are the "$eh_func_beginXXX" labels. Mips overrides the debug label suffix from ":" to "=." . This initial patch fixes exceptions. More changes most likely will be needed to DwarfCFException to make all of this work for actual debugging. These changes will be to emit debug labels in some places where a simple label is emitted now. Some historical discussion on this from gcc can be found at: http://gcc.gnu.org/ml/gcc-patches/2008-08/msg00623.html http://gcc.gnu.org/ml/gcc-patches/2008-11/msg01273.html git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170279 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08Add the `lto_codegen_set_export_dynamic' function.Bill Wendling
This function sets the `_exportDynamic' ivar. When that's set, we export all symbols (e.g. we don't run the internalize pass). This is equivalent to the `--export-dynamic' linker flag in GNU land: --export-dynamic When creating a dynamically linked executable, add all symbols to the dynamic symbol table. The dynamic symbol table is the set of symbols which are visible from dynamic objects at run time. If you do not use this option, the dynamic symbol table will normally contain only those symbols which are referenced by some dynamic object mentioned in the link. If you use dlopen to load a dynamic object which needs to refer back to the symbols defined by the program, rather than some other dynamic object, then you will probably need to use this option when linking the program itself. The Darwin linker will support this via the `-export_dynamic' flag. We should modify clang to support this via the `-rdynamic' flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169656 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05Added a option to the disassembler to print immediates as hex.Kevin Enderby
This is for the lldb team so most of but not all of the values are to be printed as hex with this option. Some small values like the scale in an X86 address were requested to printed in decimal without the leading 0x. There may be some tweaks need to places that may still be in decimal that they want in hex. Specially for arm. I made my best guess. Any tweaks from here should be simple. I also did the best I know now with help from the C++ gurus creating the cleanest formatImm() utility function and containing the changes. But if someone has a better idea to make something cleaner I'm all ears and game for changing the implementation. rdar://8109283 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169393 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-24libLTO: Add a utility method to initialize the disassemblers.Benjamin Kramer
Necessary to give disassembler users (like darwin's otool) a possibility to dlopen libLTO and still initialize the required LLVM bits. This used to go through libMCDisassembler but that's a gross layering violation, the MC layer can't pull in functions from the targets.
