* [llvm-readobj][test] - Cleanup and split tests in tools/llvm-readobj folder.Georgii Rymar2019-12-121-302/+0
| | | | | | | | | | | | | tools/llvm-readobj currently contains tests that are either general for all file types or that mix file types inside. This patch refactors these test and leaves only general tests in that folder. All other tests were moved to ELF/COFF/MachO and wasm accordingly. I tried to minimize amount of changes, so most of the test parts remained unchanged. Any further refactorings and improvements for particular tests should be done independently from this patch.

* [llvm-readobj][test] - Move platform specific test cases and their inputs to ↵Georgii Rymar2019-12-101-9/+9
| | | | | | | | | | | | separate folders. This creates the next subfolders in the test directory: "COFF", "ELF", "MachO", "wasm". I've also removed platform specific prefixes, like "coff-*". One unused binary was removed as well: `Inputs/relocs.obj.elf-mips` Differential revision: https://reviews.llvm.org/D71203
* [test][tools] Add missing and improve testingJames Henderson2019-12-091-11/+0
| | | | | | | | | | | Mostly this adds testing for certain aliases in more explicit ways. There are also a few tidy-ups, and additions of missing testing, where the feature was either not tested at all, or not tested explicitly and sufficiently.

* [llvm-readobj] Change -long-option to --long-option in tests. NFCFangrui Song2019-05-011-1/+1
| | | | | | | | | | We use both -long-option and --long-option in tests. Switch to --long-option for consistency. In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf. While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf). llvm-svn: 359649
* [WebAssembly] Rename relocations from R_WEBASSEMBLY_ to R_WASM_Sam Clegg2019-02-041-4/+4
| | | | | | | | | | | | | | | | See https://github.com/WebAssembly/tool-conventions/pull/95. This is less typing and IMHO more readable, and it also fits with our naming around the binary format which tends to use the short name. e.g. include/llvm/BinaryFormat/Wasm.h tools/llvm-objdump/WasmDump.cpp etc..

* [WebAssembly] Add first claass symbol table to wasm objectsSam Clegg2018-02-231-2/+2
| | | | | | | | | | | | | | | | | | | | This is combination of two patches by Nicholas Wilson: 1. https://reviews.llvm.org/D41954 2. https://reviews.llvm.org/D42495 Along with a few local modifications: - One change I made was to add the UNDEFINED bit to the binary format to avoid the extra byte used when writing data symbols. Although this bit is redundant for other symbols types (i.e. undefined can be implied if a function or global is a wasm import) - I prefer to be explicit and consistent and not have derived flags. - Some field renaming. - Some reverting of unrelated minor changes. - No test output differences.

* Improve the --expand-relocs handling of MachO.Rafael Espindola2015-06-181-84/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* llvm-readobj: fix MachO relocatoin printing a bit.Tim Northover2014-07-041-26/+26
| | | | | | | | | | | | | | | | 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
* Change how we iterate over relocations on ELF.Rafael Espindola2013-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 182908
* Use pointers to iterate over symbols.Rafael Espindola2013-04-241-26/+26
| | | | | | | | 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

* Add 179294 back, but don't use bit fields so that it works on big endian hosts.Rafael Espindola2013-04-121-7/+7
| | | | | | | | | | | | | | 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

* Implements low-level object file format specific output for COFF andEric Christopher2013-04-031-0/+32
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.
