Perf, eh_elf flavour

This repository contains a fork of perf, the profiler from the Linux kernel repository, modified in a way to interface it with eh_elfs and (hopefully) speeding it up on complicated DWARF frames

Compiling

Clone the Linux kernel repository or get a tarball of its source tree, then replace the tools/perf directory with a clone of this repo. Then, cd tools/perf and make, without forgetting to give the compilation tools the right version of libunwind, eg. by setting LD_RUN_PATH and LIBUNWIND_DIR:

    export LD_RUN_PATH=$HOME/local/libunwind/lib
    export LIBUNWIND_DIR=$HOME/local/libunwind
    make

This works at least with the linux repository at v4.17-rc5
