* [llvm-readobj] Extend the output of -elf-section-groupsAlexander Shaposhnikov2018-03-122-0/+8
| | | | | | | | | | | | | | This diff extends the output of -elf-section-groups (llvm style, gnu style is unchanged since it's meant to be compatible with binutils readelf) with sh_link and sh_info. This change will enable us to use llvm-readobj -elf-section-groups for testing llvm-objcopy's support for .group sections. Test plan: make check-all Differential revision: https://reviews.llvm.org/D44280 llvm-svn: 327341
* Reland "[DebugInfo] Support DWARF expressions in eh_frame"Rafael Auler2018-03-082-0/+216
| | | | | | | | | | Summary: Original change was D43313 (r326932) and reverted by r326953 because it broke an LLD test and a windows build. The LLD test was already fixed in lld commit r326944 (thanks maskray). This is the original change with the windows build fixed. llvm-svn: 326970
* Revert r326932: [DebugInfo] Support DWARF expressions in eh_frameRui Ueyama2018-03-072-216/+0
| | | | | | This reverts commit rr326932 because it broke lld/test/ELF/eh-frame-hdr-augmentation.s. llvm-svn: 326953
* [DebugInfo] Support DWARF expressions in eh_frameRafael Auler2018-03-072-0/+216
| | | | | | | | | | | | | | | | | | This patch enhances DWARFDebugFrame with the capability of parsing and printing DWARF expressions in CFI instructions. It also makes FDEs and CIEs accessible to lib users, so they can process them in client tools that rely on LLVM. To make it self-contained with a test case, it teaches llvm-readobj to be able to dump EH frames and checks they are correct in a unit test. The llvm-readobj code is Maksim Panchenko's work (maksfb).

* [WebAssembly] Reorder reloc sections to come between symtab and nameNicholas Wilson2018-03-052-5/+5
| | | | | | | | | | | This is required in order to enable relocs to be validated as they are read in. Also update tests with new section ordering. Differential Revision: https://reviews.llvm.org/D43940 llvm-svn: 326694

* [WebAssembly] Remove DataSize from linking metadata sectionSam Clegg2018-02-271-1/+0
| | | | | | | | | | | Neither the linker nor the runtime need this information anymore. We were originally using this to model BSS size but the plan is now to use the segment metadata to allow for BSS segments. Differential Revision: https://reviews.llvm.org/D41366 llvm-svn: 326267
* [WebAssembly] Add first claass symbol table to wasm objectsSam Clegg2018-02-234-45/+20
| | | | | | | | | | | | | | | | | | | | 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.

* Mark two tests REQUIRES: x86-registered-backendJustin Bogner2018-01-311-0/+1
| | | | | | | | These were introduced in r323783 and use an X86 triple. I'll follow up on the list to check if it would make more sense to remove the triple and mark them REQUIRES: default_triple instead. llvm-svn: 323847
* CodeGen: support an extension to pass linker options on ELFSaleem Abdulrasool2018-01-301-0/+11
| | | | | | | | | | | | | | | | | | Introduce an extension to support passing linker options to the linker. These would be ignored by older linkers, but newer linkers which support this feature would be able to process the linker. Emit a special discarded section `.linker-option`. The content of this section is a pair of strings (key, value). The key is a type identifier for the parameter. This allows for an argument free parameter that will be processed by the linker with the value being the parameter. As an example, `lib` identifies a library to be linked against, traditionally the `-l` argument for Unix-based linkers with the parameter being the library name. Thanks to James Henderson, Cary Coutant, Rafael Espinolda, Sean Silva for the valuable discussion on the design of this feature. llvm-svn: 323783
* [WebAssembly] Remove debug names from symbol tableSam Clegg2018-01-171-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Get rid of DEBUG_FUNCTION_NAME symbols. When we actually debug data, maybe we'll want somewhere to put it... but having a symbol that just stores the name of another symbol seems odd. It means you have multiple Symbols with the same name, one containing the actual function and another containing the name! Store the names in a vector on the WasmObjectFile when reading them in. Also stash them on the WasmFunctions themselves. The names are //not// "symbol names" or aliases or anything, they're just the name that a debugger should show against the function body itself. NB. The WasmObjectFile stores them so that they can be exported in the YAML losslessly, and hence the tests can be precise. Enforce that the CODE section has been read in before reading the "names" section. Requires minor adjustment to some tests. Patch by Nicholas Wilson!

* [llvm-readobj] Support 'GNU' style for MIPS GOT/PLT dumpingSimon Atanasyan2017-12-212-2/+166
| | | | | | | | | | This change adds `printMipsGOT` and `printMipsPLT` methods to the `DumpStyle` class and overrides them in the `GNUStyle` and `LLVMStyle` descendants. To pass information about GOT/PLT layout into these methods, the `MipsGOTParser` class has been extended to hold all necessary data. llvm-svn: 321253
* [llvm-readobj] Print static MIPS GOTSimon Atanasyan2017-12-022-1/+38
| | | | | | | | | | If a linked binary file contains a dynamic section, the GOT layout defined by the dynamic section entries. In a statically linked file the GOT is just a series of entries. This change teaches `llvm-readobj` to print the GOT in that case. That provides a feature parity with GNU `readelf`. llvm-svn: 319616

| | | | | | | | | | | | | | | | | | | object files This change only treats imported and exports functions and globals as symbol table entries the object has a "linking" section (i.e. it is relocatable object file). In this case all globals must be of type I32 and initialized with i32.const. This was previously being assumed but not checked for and was causing a failure on big endian machines due to using the wrong value of then union.

| | | | | | | | | | | | | Accept and ignore --wide/-W. In GNU readelf this switch is necessary to get the output format that's consistent between 32-bit and 64-bit targets. llvm-readobj always produces that output format.

* [llvm-readobj] Accept -S as an alias for --sectionsPetr Hosek2017-07-181-1/+1
| | | | | | | | | | | | | | | In GNU readelf, the short option for --sections is upper-case -S. Note that GNU uses lower-case -s to mean --symbols, while LLVM uses -s to mean --sections and -t to mean --symbols (-t has yet a different meaning in GNU). So command-line uses with -S can now be compatible, but uses with -s or -t are still incompatible. Patch by Roland McGrath Differential Revision: https://reviews.llvm.org/D33872 llvm-svn: 308392
