From 314ee04268c2556f987000d76fba6deb0cf73978 Mon Sep 17 00:00:00 2001 From: Artyom Skrobov Date: Wed, 25 Nov 2015 19:41:11 +0000 Subject: Expose isXxxConstant() functions from SelectionDAGNodes.h (NFC) Summary: Many target lowerings copy-paste the code to test SDValues for known constants. This code can instead be shared in SelectionDAG.cpp, and reused in the targets.
