[PATCH] D40425: Extending CFGPrinter and CallPrinter with Heat Colors

[Rodrigo Caetano Rocha via Phabricator via llvm-commits]

rcorcs updated this revision to Diff 125125.
rcorcs added a comment.

Updates the CFGPrinters to work on a per-module basis.

Because the heat factor of each basic block is computed relative to others within the scope being analysed
if we compute the heat factor relative to the basic block with the maximum frequency within the whole module,
it should provide heat colors more representative to the true block frequencies than if we compute the same values
on a per-function basis.
Ideally, the heat map would be computed using profiling information and considering the whole program (perhaps after linking all modules).
