From 738073c4aa474e27c9d3c991daf593bddce54718 Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Thu, 29 Aug 2013 03:25:05 +0000 Subject: Add useAA() to TargetSubtargetInfo There are several optional (off-by-default) features in CodeGen that can make use of alias analysis. These features are important for generating code for some kinds of cores (for example the (in-order) PPC A2 core). This adds a useAA() function to TargetSubtargetInfo to allow these features to be enabled by default on a per-subtarget basis. Here is the first use of this function: To control the default of the -enable-aa-sched-mi feature. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189563 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/TargetSubtargetInfo.cpp | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'lib/Target') diff --git a/lib/Target/TargetSubtargetInfo.cpp b/lib/Target/TargetSubtargetInfo.cpp index af0cef6..f624c32 100644 --- a/lib/Target/TargetSubtargetInfo.cpp +++ b/lib/Target/TargetSubtargetInfo.cpp @@ -35,3 +35,7 @@ bool TargetSubtargetInfo::enablePostRAScheduler( return false; } +bool TargetSubtargetInfo::useAA() const { + return false; +} + -- cgit v1.1
