Libunwind (LLVM)

This package contains the libunwind library from LLVM together with make files for building them inside the L4Re tree.

We maintain one libunwind version per LLVM major version, assuming that there are no breaking changes in libunwind within LLVM minor versions, neither in terms of forward nor backward compatibility.

Package structure

The contrib directory contains unmodified directories from each supported major LLVM version.

The build directory contains the build infrastructure to build libunwind with L4Re's BID build system.

The libunwind_llvm package is split into two packages:

libunwind_llvm

Main package, contains contrib code and build infrastructure. Provides static (libunwind_llvm.a) variant of the libunwind_llvm.

libunwind_llvm-pure

Provides static variant of libunwind_llvm without L4 specific functionality (libunwind_llvm-pure.a).

GCC compatible unwind interface

The header file (unwind.h) specifying the GCC compatible unwind interface for libunwind_llvm, as required by libstdc++ for example, is not part of this library, but is provided by Clang itself.
