prof-flamegraph

Generate flamegraphs from ghc RTS .prof files.

This is a small tool to convert ghc `.prof` files into a format consumable by FlameGraph.

Obtain `.prof` files by compiling with `--enable-profiling` and running with `+RTS -P -RTS`.

$ cat app.prof |
  prof-flamegraph |

This is a fork of https://github.com/fpco/ghc-prof-flamegraph which hides the intermediate flamegraph format.
