* 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

* llvm-readobj: Add support for reading relocations in the Android packed format.Peter Collingbourne2017-10-259-0/+201
| | | | | | | | | | | This is in preparation for testing lld's upcoming relocation packing feature (D39152). I have verified that this implementation correctly unpacks the relocations from a Chromium DSO built with gold and the Android relocation packer for ARM32 and ARM64.

* [codeview] Add support for inlinee listsReid Kleckner2017-10-232-0/+38
| | | | | | | | | | | This adds type index discovery and dumper support for symbol record kind 0x1168, which is a list of inlined function ids. This symbol kind is undocumented, but S_INLINEES is consistent with the existing nomenclature. Fixes PR34222 llvm-svn: 316398

* [WebAssembly] Only treat imports/exports as symbols when reading relocatable ↵Sam Clegg2017-09-061-6/+6
| | | | | | | | | | | | | | | | | | | 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.

* [Object] Initialize LoadConfig member to nullReid Kleckner2017-08-072-0/+5
| | | | | | | | | | Executables may not contain a load config, and clients should be able to test for nullability. Previously we'd return uninitialized memory. Now getLoadConfig32/64 return valid pointers or null. Fixes PR34108 llvm-svn: 310308
* [llvm-readobj] Install llvm-readelf aliasPetr Hosek2017-07-191-0/+2

* [llvm-readobj] Accept (and ignore) --wide (-W) command-line switchPetr Hosek2017-07-181-0/+6
| | | | | | | | | | | | | 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. Patch by Roland McGrath Differential Revision: https://reviews.llvm.org/D33873 llvm-svn: 308396
* [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

* [llvm-readobj] Improve errors on invalid binarySam Clegg2017-05-101-0/+7
| | | | | | | | | | | | | | The previous code was discarding the error message from createBinary() by calling errorToErrorCode(). This meant that such error were always reported unhelpfully as "Invalid data was encountered while parsing the file".
