* AArch64: print relocation addends if present on AArch64Tim Northover2013-06-17
| | | | | | | llvm-objdump should provide some way of printing out the addends present in the .rela sections for debugging purposes if nothing else. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184072 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj] Initial ELF section support.Sean Silva2013-06-13
| | | | | | | The current functionality is extremely basic and a bit rough around the edges, but it will flesh out in future commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183953 91177308-0d34-0410-b5e6-96231b3b80d8
* readobj: Dump PE/COFF optional records.Rui Ueyama2013-06-12

* [PECOFF] Remove COFF header from PE header for simplicity.Rui Ueyama2013-06-11
| | | | | | | | | | | | | | | | COFF header is always present both in executable and in object file. PE header is present only in executable. So the natural way to handle PE/COFF file is treating COFF is mandatory header and PE is optional. Current data structre does not allow it, because PE header includes COFF header. Removing COFF header will simplify the code to handle PE/COFF files.

* [yaml2obj] Initial ELF support.Sean Silva2013-06-10
| | | | | | | | | Currently, only emitting the ELF header is supported (no sections or segments). The ELFYAML code organization is broadly similar to the COFFYAML code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183711 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach llvm-objdump with the -macho parser how to use the data in code tableKevin Enderby2013-06-06
| | | | | | | | | | | | | | | | from the LC_DATA_IN_CODE load command. And when disassembling print the data in code formatted for the kind of data it and not disassemble those bytes. I added the format specific functionality to the derived class MachOObjectFile since these tables only appears in Mach-O object files. This is my first attempt to modify the libObject stuff so if folks have better suggestions how to fit this in or suggestions on the implementation please let me know. rdar://11791371 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183424 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename operator== parameter to `RHS`.Sean Silva2013-06-05
| | | | | | The previous name `Ref` is overly generic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183354 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove error-prone methods of BinaryRef.Sean Silva2013-06-05
| | | | | | | | | | | | | A user shouldn't care about the internal state, and these methods by their very nature require asserting a predicate on the internal state. As such, they cannot be used safely without introducing hidden long-distance dependencies on the manner of construction of the BinaryRef. Use writeAsBinary(raw_ostream &) and writeAsHex(raw_ostream &) if you need to access the data in a binary or hex format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183353 91177308-0d34-0410-b5e6-96231b3b80d8
* Add writeAsHex(raw_ostream &) method to BinaryRef.Sean Silva2013-06-05
| | | | | | | This hides the implementation. A future commit will remove the error-prone getHex() and getBinary() methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183352 91177308-0d34-0410-b5e6-96231b3b80d8

* Add BinaryRef binary_size() method.Sean Silva2013-06-05
| | | | | | This avoids making assumptions about the data representation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183349 91177308-0d34-0410-b5e6-96231b3b80d8
* Comment BinaryRef::Data.Sean Silva2013-06-05
| | | | | | Also, state an invariant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183348 91177308-0d34-0410-b5e6-96231b3b80d8
* Add writeAsBinary(raw_ostream &) method to BinaryRef.Sean Silva2013-06-05
| | | | | | | | | | | Previously, yaml2coff.cpp had a writeHexData static helper function to do this, but it is generally useful functionality. Also, validate hex strings up-front to avoid running having to handle errors "deep inside" the yaml2obj code (it also gives better diagnostics than it used to). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183345 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't hide the first ELF symbol.Rafael Espindola2013-06-05
| | | | | | | | The first symbol on ELF is dummy, but it has a defined content and readelf normally displays it. With this change llvm-readobj also displays it and we can check that llvm-mc output is correct according to the standard. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183337 91177308-0d34-0410-b5e6-96231b3b80d8
* Represent symbols with a SymbolIndex,SectionIndex pair.Rafael Espindola2013-06-05
| | | | | | | | | | | With this patch we use the SectionIndex directly, instead of counting the number of symbol tables. This saves a DenseMap lookup every time we want to find which symbol a relocation refers to. Also simplify based on the fact that there is at most one SHT_SYMTAB and one SHT_DYNSYM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183326 91177308-0d34-0410-b5e6-96231b3b80d8

* Handle relocations that don't point to symbols.Rafael Espindola2013-06-05
| | | | | | | | In ELF (as in MachO), not all relocations point to symbols. Represent this properly by using a symbol_iterator instead of a SymbolRef.

* Change how we iterate over relocations on ELF.Rafael Espindola2013-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | For COFF and MachO, sections semantically have relocations that apply to them. That is not the case on ELF. In relocatable objects (.o), a section with relocations in ELF has offsets to another section where the relocations should be applied. In dynamic objects and executables, relocations don't have an offset, they have a virtual address. The section sh_info may or may not point to another section, but that is not actually used for resolving the relocations. This patch exposes that in the ObjectFile API. It has the following advantages: * Most (all?) clients can handle this more efficiently. They will normally walk all relocations, so doing an effort to iterate in a particular order doesn't save time. * llvm-readobj now prints relocations in the same way the native readelf does. * probably most important, relocations that don't point to any section are now visible. This is the case of relocations in the rela.dyn section. See the updated relocation-executable.test for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182908 91177308-0d34-0410-b5e6-96231b3b80d8

* [PowerPC] Add some missing PPC64 relocsUlrich Weigand2013-05-08
| | | | | | | | | | | | | | | All R_PPC_... relocs should also be present (using the same number) under the corresponding R_PPC64_... name. The latter were missing for a couple of cases, which this patch adds. This is not a big problem when emitting the reloc, because we can just use the R_PPC_... define instead. But it is a problem when *dumping* relocations e.g. using llvm-readobj, because this will expect only R_PPC64_... values when inspecting a ppc64 ELF file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181451 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for reading ARM ELF build attributes.Amara Emerson2013-05-03
| | | | | | | | | | | | Build attribute sections can now be read if they exist via ELFObjectFile, and the llvm-readobj tool has been extended with an option to dump this information if requested.

* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-29
| | | | | | | | | | | | | For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

* Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-26
| | | | | | | | | | | | | | | | | | | | | For Mach-O there were 2 implementations for parsing object files. A standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which implements the generic interface in llvm/Object/ObjectFile.h. This patch adds the missing features to MachO.h, moves macho-dump to use MachO.h and removes ObjectFile.h. In addition to making sure that check-all is clean, I checked that the new version produces exactly the same output in all Mach-O files in a llvm+clang build directory (including executables and shared libraries). To test the performance, I ran macho-dump over all the files in a llvm+clang build directory again, but this time redirecting the output to /dev/null. Both the old and new versions take about 4.6 seconds (2.5 user) to finish. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180624 91177308-0d34-0410-b5e6-96231b3b80d8
