[Teresa Johnson via Phabricator via llvm-commits]

tejohnson added a comment.

Examples of the dot files (for new test llvm/test/Transforms/PGHOContextDisambiguation/basic.ll), also converted to png format, are attached:
basic.ll.tmp.ccg.prestackupdate.dot[.png] is the dot file generated after adding all allocation nodes, and the stack nodes corresponding to the memprof metadata on those allocations.
basic.ll.tmp.ccg.postbuild.dot[.png] is the dot file generated after matching callsite metadata from other calls to the stack nodes.

The color scheme on the nodes/edges: blue = cold, red = noncold, purple = both
In the dot file format there is a tooltip that shows the assigned context ids for each node and edge.F26086741: basic.ll.tmp.ccg.postbuild.dot.png <https://reviews.llvm.org/F26086741>
