* tools: add support for decoding ARM attributesSaleem Abdulrasool2014-01-30
| | | | | | | | Enhance the ARM specific parsing support in llvm-readobj to support attributes. This allows for simpler tests to validate encoding of the build attributes as specified in the ARM ELF specification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200450 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename IMAGE_DLL_CHARACTERISTICS_HIGH_ENTROPY_VA.Rui Ueyama2014-01-27
| | | | | | | editbin.exe and link.exe both accepts /highentropyva option to set this bit, so doing s/VIRTUAL_ADDRESS/VA/ should make sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200191 91177308-0d34-0410-b5e6-96231b3b80d8
* COFF: Add a missing enum value for high entropy ASLR.Rui Ueyama2014-01-26
| | | | | | | | | That bit is not documented in the PE/COFF spec published by Microsoft, so we don't know the official name of it. I named this bit IMAGE_DLL_CHARACTERISTICS_HIGH_ENTROPY_VIRTUAL_ADDRESS because the bit is reported as "high entropy virtual address" by dumpbin.exe, git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200121 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-readobj: add support for PE32+ (Windows 64 bit executable).Rui Ueyama2014-01-26
| | | | | | | | | | | | PE32+ supports 64 bit address space, but the file format remains 32 bit. So its file format is pretty similar to PE32 (32 bit executable). The differences compared to PE32 are (1) the lack of "BaseOfData" field and (2) some of its data members are 64 bit. In this patch, I added a new member function to get a PE32+ Header object to COFFObjectFile class and made llvm-readobj to use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200117 91177308-0d34-0410-b5e6-96231b3b80d8
* tools: support decoding ARM EHABI opcodes in readobjSaleem Abdulrasool2014-01-21
| | | | | | | | | | | | | | Add support to llvm-readobj to decode the actual opcodes. The ARM EHABI opcodes are a variable length instruction set that describe the operations required for properly unwinding stack frames. The primary motivation for this change is to ease the creation of tests for the ARM EHABI object emission as well as the unwinding directive handling in the ARM IAS. Thanks to Logan Chien for an extra test case! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199708 91177308-0d34-0410-b5e6-96231b3b80d8

* tests: disable ARM unwinding tests if ARM is unavailableSaleem Abdulrasool2014-01-08
| | | | | | | | | | Appease the buildbots for targets which do not build the ARM support by moving the ARM specific test into a subdirectory and use the lit configuration to disable them appropriately. Thanks to chapuni and thakis for explaining how to do this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198736 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-readobj: add support for ARM EHABI unwind infoSaleem Abdulrasool2014-01-08
| | | | | | | | | | | | | | | This adds some preliminary support for decoding ARM EHABI unwinding information. The major functionality that remains from complete support is bytecode translation. Each Unwind Index Table is printed out as a separate entity along with its section index, name, offset, and entries. Each entry lists the function address, and if possible, the name, of the function to which it corresponds. The encoding model, personality routine or index, and byte code is also listed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198734 91177308-0d34-0410-b5e6-96231b3b80d8

* [tests] Cleanup initialization of test suffixes.Daniel Dunbar2013-08-16
| | | | | | | | | | | | | | | | | - Instead of setting the suffixes in a bunch of places, just set one master list in the top-level config. We now only modify the suffix list in a few suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py). - Aside from removing the need for a bunch of lit.local.cfg files, this enables 4 tests that were inadvertently being skipped (one in Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been XFAILED). - This commit also fixes a bunch of config files to use config.root instead of older copy-pasted code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188513 91177308-0d34-0410-b5e6-96231b3b80d8

* COFFDumper: Dump data directory entries.Rui Ueyama2013-07-18
| | | | | | | | | | | | | | | | | Summary: Dump optional data directory entries in the PE/COFF header, so that we can test the output of LLD linker. This patch updates the test binary file, but the source of the binary is the same. I just re-linked the file. I don't know how the previous file was linked, but the previous file did not have any data directory entries for some reason.

* 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
* 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
* Use pointers to iterate over symbols.Rafael Espindola2013-04-24
| | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180214 91177308-0d34-0410-b5e6-96231b3b80d8

* Implements low-level object file format specific output for COFF andEric Christopher2013-04-03
ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.
