Is anyone else seeing a bootstrap failure on x86_64-apple-darwin15 in current trunk?

The trigger for this build failure is the usage of -DLLVM_BUILD_EXTERNAL_COMPILER_RT:BOOL=ON. If I drop that

Kevin Enderby added those symbol uses in r270491. It has a cmake feature test, and all the uses of those symbols appear bracketed in HAVE_LIBXAR, so I don't know what went wrong for you.

Hi Jack, Just a guess here, this may be the bug Chris helped me out with in the use of the include file xar/xar.h which is not C++ safe. I needed to wrap my include via: #ifdef HAVE_LIBXAR extern "C" { #include <xar/xar.h> } #endif I think we may need some help from Chris to track this down. I’ll bug him in a bit to see if he can help us on this. Kev > On May 24, 2016, at

My read of this problem is as follows. While libLLVM.dylib is being linked against -lxar when -DLLVM_LINK_LLVM_DYLIB:BOOL=ON is passed to cmake, the libLLVM.dylib is created with -Wl,-dead_strip such that

...self-explanatory), but not at documenting classes. I'd encourage anyone who has added a class to LLVM to revisit it and see if they can improve the documentation. Another example is object::ObjectFile. You can cast<> or dyn_cast<> these down to object::COFFObjectFiles or object::MachOObjectFiles easily, but object::ELFObjectFile is a template class and there's no documentation of what the template parameter should be, of it if's possible to infer it from the object::ObjectFile somehow. David Who has spent the last week writing a tool that uses the MC layer and found the lack of...

Hi,   We propose llvm-dwarfutil - a dsymutil-like tool for ELF.   Any thoughts on this?   Thanks in advance, Alexey. ====================================================================== llvm-dwarfutil(Apndx A) - is a tool that is used for processing debug info(DWARF) located in built binary files to improve debug info quality, reduce debug info size and accelerate debug info processing.

It sounds like what you’re asking is, rather that universally calling RelocationRef::getOffset inside llvm-objdump.cpp I should: * Check if Obj “isRelocatableObject” * If it is, call RelocationRef::getOffset() * If it isn’t o Call RelocationRef::getAddress() o Build an ordered map of all sections and their bounds, check if the relocation lands within a section o
