From 2477320a8d9de58ede68e2645ea53c10f71dcd57 Mon Sep 17 00:00:00 2001 From: Aart Bik Date: Thu, 26 Apr 2018 10:28:51 -0700 Subject: Step 1 of 2: conditional passes. Rationale: The change adds a return value to Run() in preparation of conditional pass execution. The value returned by Run() is best effort, returning false means no optimizations were applied or no useful information was obtained. I filled in a few cases with more exact information, others still just return true. In addition, it integrates inlining as a regular pass, avoiding the ugly "break" into optimizations1 and optimziations2.
