From f0a31e107973f3bde7dd54cd7610082b104922db Mon Sep 17 00:00:00 2001 From: Santiago Aboy Solanes Date: Fri, 12 Jan 2024 18:40:49 +0000 Subject: Revert "Restrict the use of ConstantFolding's VisitIf" This reverts commit 5eb1fd0dae3832ceee2102613bb08c291daca6f3. Reason for revert: In aosp/2903248 we implemented a faster way of doing `ReplaceUsesDominatedBy` which is used by `VisitIf`. The impact of `VisitIf` is now small enough that running VisitIf in all passes is faster that the previous implementation running some of the time. This CLs re-enables the optimization in all constant folding passes because: A) Lets this optimization (and others that can use the result) kick in earlier B) Run it for callee graphs in the inliner (which has been disabled as of CL aosp/2543831) C) Consistency of the ConstantFolding pass, which helps to have a simpler mental model Bug: 278626992 Test: art/test/testrunner/testrunner.py --host --64 --optimizing -b Test: Locally compiled GMS and compared time to compile Change-Id: I5dc5f591557c8de0bc4d23dbfd0b91b5b7e56ab5 --- compiler/optimizing/optimization.h | 1 - 1 file changed, 1 deletion(-) (limited to 'compiler/optimizing/optimization.h') diff --git a/compiler/optimizing/optimization.h b/compiler/optimizing/optimization.h index 57c5f4639c..55aa8f914b 100644 --- a/compiler/optimizing/optimization.h +++ b/compiler/optimizing/optimization.h @@ -67,7 +67,6 @@ class HOptimization : public ArenaObject { // field is preferred over a string lookup at places where performance matters. // TODO: generate this table and lookup methods below automatically? enum class OptimizationPass { - kAggressiveConstantFolding, kAggressiveInstructionSimplifier, kBoundsCheckElimination, kCHAGuardOptimization, -- cgit v1.2.3-59-g8ed1b
