* ARM: support .watchos_version_min and .tvos_version_min.Tim Northover2015-10-281-30/+38
| | | | | | | | These MachO file directives are used by linkers and other tools to provide compatibility information, much like the existing .ios_version_min and .macosx_version_min. llvm-svn: 251569
* [llvm-readobj/MachO] Ensure we always have valid CmdName/SegmentName.Davide Italiano2015-09-221-2/+2
| | | | | | | | Otherwise we might end up printing garbage while dumping. Differential Revision: http://reviews.llvm.org/D13041 llvm-svn: 248239
* [llvm-readobj] MachO -- dump LinkerOptions load command.Davide Italiano2015-09-091-0/+20
| | | | | | | | | | | | | | | | | | | | Example output: Linker Options { Size: 32 Count: 2 Strings [ Value: -framework Value: Cocoa ] } There were only two tests using this -- so I converted them as part of this commit rather than separately. Differential Revision: http://reviews.llvm.org/D12702 llvm-svn: 247106
* [llvm-readobj] MachO: dump the correct field.Davide Italiano2015-09-041-1/+1
| | | | | | | This was found while converting a test from macho-dump to llvm-readobj and will once I commit the converted test. llvm-svn: 246868

* Convert getSymbolSection to return an ErrorOr.Rafael Espindola2015-08-071-2/+3
| | | | | | | This function can actually fail since the symbol contains an index to the section and that can be invalid. llvm-svn: 244375
* llvm-readobj: call exit(1) on error.Rafael Espindola2015-07-201-11/+7
| | | | | | | | | llvm-readobj exists for testing llvm. We can safely stop the program the first time we know the input in corrupted. This is in preparation for making it handle a few more broken files. llvm-svn: 242656
* Return ErrorOr from SymbolRef::getName.Rafael Espindola2015-07-021-3/+5
| | | | | | | | | | | | This function can really fail since the string table offset can be out of bounds. Using ErrorOr makes sure the error is checked. Hopefully a lot of the boilerplate code in tools/* can go away once we have a diagnostic manager in Object. llvm-svn: 241297
* Don't return error_code from a function that doesn't fail.Rafael Espindola2015-06-301-2/+1

* [StackMaps] Add a lightweight parser for stackmap version 1 sections.Lang Hames2015-06-261-0/+31
| | | | | | | | | | The parser provides a convenient interface for reading llvm stackmap v1 sections in object files. This patch also includes a new option for llvm-readobj, '-stackmap', which uses the parser to pretty-print stackmap sections for debugging/testing purposes. llvm-svn: 240860
* Make getRelocationSection MachO only.Rafael Espindola2015-06-191-1/+1
| | | | | | | | | | | | | | There are 3 types of relocations on MachO * Scattered * Section based * Symbol based On ELF and COFF relocations are symbol based. We were in the strange situation that we abstracted over two of them. This makes section based relocations MachO only. llvm-svn: 240149
* Improve the --expand-relocs handling of MachO.Rafael Espindola2015-06-181-17/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In a relocation target can take 3 basic forms * A r_value in scattered relocations. * A symbol in external relocations. * A section is non-external relocations. Have the dump reflect that. With this change we go from CHECK-NEXT: Extern: 0 CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5) CHECK-NEXT: Symbol: 0x2 CHECK-NEXT: Scattered: 0 To just // CHECK-NEXT: Type: X86_64_RELOC_SUBTRACTOR (5) // CHECK-NEXT: Section: __data (2) Since the relocation is with a section, we print the seciton name and don't need to say that it is not scattered or external. Someone motivated can add further special cases for things like ARM64_RELOC_ADDEND and ARM_RELOC_PAIR. llvm-svn: 240073
* Remove unused variable, found with gcc-5.1 -Wunused-variable.Patrik Hagglund2015-04-271-25/+0
| | | | | | | The variable, MachOSectionTypes, seems to have been unused since its introduction in r178679. llvm-svn: 235863
* Implement MachODumper::printFileHeadersFrederic Riss2014-11-171-1/+175
| | | | | | | | Patch by Chilledheart. Differential Revision: http://reviews.llvm.org/D6163 llvm-svn: 222115
* Remove bogus std::error_code returns form SectionRef.Rafael Espindola2014-10-081-5/+2
| | | | | | | | | | | | | | There are two methods in SectionRef that can fail: * getName: The index into the string table can be invalid. * getContents: The section might point to invalid contents. Every other method will always succeed and returning and std::error_code just complicates the code. For example, a section can have an invalid alignment, but if we are able to get to the section structure at all and create a SectionRef, we will always be able to read that invalid alignment. llvm-svn: 219314
* Object: BSS/virtual sections don't have contentsDavid Majnemer2014-09-261-3/+8
| | | | | | | | | | | | Users of getSectionContents shouldn't try to pass in BSS or virtual sections. In all instances, this is a bug in the code calling this routine. N.B. Some COFF implementations (like CL) will mark their BSS sections as taking space on disk. This would confuse COFFObjectFile into thinking the section is larger than the file. llvm-svn: 218549
* Remove 'virtual' keyword from methods markedwith 'override' keyword.Craig Topper2014-08-301-6/+6

* llvm-readobj: fix MachO relocatoin printing a bit.Tim Northover2014-07-041-6/+18
| | | | | | | | | | | | | | | | There were two issues here: 1. At the very least, scattered relocations cannot use the same code to determine the corresponding symbol being referred to. For some reason we pretend there is no symbol, even when one actually exists in the symtab, so to match this behaviour getRelocationSymbol should simply return symbols_end for scattered relocations. 2. Printing "-" when we can't get a symbol (including the scattered case, but not exclusively), isn't that helpful. In both cases there *is* interesting information in that field, so we should print it. As hex will do. Small part of rdar://problem/17553104 llvm-svn: 212332

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-2/+2
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083

* Simplify the handling of iterators in ObjectFile.Rafael Espindola2014-01-301-23/+7
| | | | | | | | | | | | None of the object file formats reported error on iterator increment. In retrospect, that is not too surprising: no object format stores symbols or sections in a linked list or other structure that requires chasing pointers. As a consequence, all error checking can be done on begin() and end(). This reduces the text segment of bin/llvm-readobj in my machine from 521233 to 518526 bytes. llvm-svn: 200442

* Handle relocations that don't point to symbols.Rafael Espindola2013-06-051-4/+3
| | | | | | | | In ELF (as in MachO), not all relocations point to symbols. Represent this properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj ELF's dumper to handle relocatios without symbols. llvm-svn: 183284
* Use pointers to iterate over symbols.Rafael Espindola2013-04-241-1/+3
| | | | | | | | While here, don't report a dummy symbol for relocations that don't have symbols. We used to says such relocations were for the first defined symbol, but now we return end_symbols(). The llvm-readobj output change agrees with otool. llvm-svn: 180214

| | | | | | | | | | | | | | 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. llvm-svn: 179345
