2017-11-02[tools] Add option to install binutils symlinksShoaib Meenai
The LLVM tools can be used as a replacement for binutils, in which case it's convenient to create symlinks with the binutils names. Add support for these symlinks in the build system. As with any other llvm tool symlinks, the user can limit the installed symlinks by only adding the desired ones to `LLVM_TOOLCHAIN_TOOLS`.

2017-07-30DebugInfo: Provide option for explicitly specifying the name of the DWP fileDavid Blaikie
If you've archived the DWP file somewhere it's probably useful to be able to just tell llvm-symbolizer where it is when you're symbolizing stack traces from the binary. This only provides a mechanism for specifying a single DWP file, good if you're symbolizing a program with a single DWP file, but it's likely if the program is dynamically linked that you might have a DWP for each dynamic library - in which case this feature won't help (at least as it's surfaced in llvm-symbolizer for now) - in theory it could be extended to specify a collection of DWP files that could all be consulted for split CU hash resolution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@309498 91177308-0d34-0410-b5e6-96231b3b80d8

2016-06-03[Symbolize] Check if the PE file has a PDB and emit an error if we can't load itReid Kleckner
Summary: Previously we would try to load PDBs for every PE executable we tried to symbolize. If that failed, we would fall back to DWARF. If there wasn't any DWARF, we'd print mostly useless symbol information using the export table. With this change, we only try to load PDBs for executables that claim to have them. If that fails, we can now print an error rather than falling back silently. This should make it a lot easier to diagnose and fix common symbolization issues, such as not having DIA or not having a PDB.

2015-06-22[Object] Search for architecures by name in ↵Frederic Riss
MachOUniversalBinary::getObjectForArch() The reason we need to search by name rather than by Triple::ArchType is to handle subarchitecture correclty. There is no different ArchType for the x86_64h architecture (it identifies itself as x86_64), or for the various ARM subarches. The only way to get to the subarch slice in an universal binary is to search by name. This issue led to hard to debug and transient symbolication failures in Asan tests (it mostly works, because the files are very similar).

Summary: Teach llvm-symbolizer about PowerPC64 ELF function descriptors. Symbols in the .opd section point to function descriptors, the first word of which is a pointer to the real function. For the purposes of symbolizing we pretend that the symbol points directly to the function.

2014-08-19Don't own the buffer in object::Binary.Rafael Espindola
Owning the buffer is somewhat inflexible. Some Binaries have sub Binaries (like Archive) and we had to create dummy buffers just to handle that. It is also a bad fit for IRObjectFile where the Module wants to own the buffer too. Keeping this ownership would make supporting IR inside native objects particularly painful. This patch focuses in lib/Object. If something elsewhere used to own an Binary, now it also owns a MemoryBuffer. This patch introduces a few new types. * MemoryBufferRef. This is just a pair of StringRefs for the data and name. This is to MemoryBuffer as StringRef is to std::string. * OwningBinary. A combination of Binary and a MemoryBuffer. This is needed for convenience functions that take a filename and return both the buffer and the Binary using that buffer. The C api now uses OwningBinary to avoid any change in semantics.
