# 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](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git)
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`:
```sh
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
