[PATCH] D29320: [XRay] A tool for Comparing xray function call graphs

[Alexis Shaw via Phabricator via llvm-commits]

varno created this revision.
Herald added a subscriber: mgorny.

This is a tool for comparing the function graphs produced by the
llvm-xray graph too. It takes the form of a new subcommand of the
llvm-xray tool 'graph-diff'.

This initial version of the patch is very rough, but it is close to
feature complete.

Depends on https://reviews.llvm.org/D29005
