...other subprojects as llgo is written in Go and depends on the Go bindings previously contributed to LLVM. llgo depends on certain third-party components, namely a copy of the Go standard library (libgo), a Go program analysis library (go.tools) and two library dependencies of the standard library (libbacktrace and libffi). These would be mirrored into the llgo repository under a third_party directory. They would retain their original licenses, which are BSD and GPLv3 with Runtime Library Exception (the latter only applies to a handful of header files; eventually we would seek to replace these). As a fi...

Hello. I was trying to compile https://github.com/llvm/llvm-project/tree/master/libunwind using: - MSVC - Clang I wasn't able to configure this project for using MSVC (directly or via clang-cl): >cmake -G Ninja -DLLVM_PATH="C:/Users/clang/llvm-project-10.0.1/llvm" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="C:\Users\clang\libunwind_llvm" ../libunwind --

Hi, In the file lld/ELF/Driver.cpp in function getCompressDebugSections we can see that the current default for lld is no debug section compression. It looks like tools like gdb, valgrind, elfutils, gcc's backtrace lib currently support compressed symbols. Since perf can use libdw from elfutils, I guess it supports it too. Do you think it's time to enable compressed debug section by
