[PATCH] D60839: [ScheduleDAGInstrs] Compute topological ordering on demand.

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

I've verified this does not change CodeGen for the test-suite + various external suites. Slightly positive impact on compile-time (-0.1 % geomean speedup for test-suite + SPEC & co, with -O1 on X86)
