From 40f8f6264d5af2c38e797e0dc59827cd231e8ff7 Mon Sep 17 00:00:00 2001 From: Jay Foad Date: Tue, 7 Dec 2010 08:25:19 +0000 Subject: PR5207: Change APInt methods trunc(), sext(), zext(), sextOrTrunc() and zextOrTrunc(), and APSInt methods extend(), extOrTrunc() and new method trunc(), to be const and to return a new value instead of modifying the object in place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121120 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/ScalarEvolution.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/Analysis/ScalarEvolution.cpp') diff --git a/lib/Analysis/ScalarEvolution.cpp b/lib/Analysis/ScalarEvolution.cpp index 7e50d3d38e..b0c1c75cb6 100644 --- a/lib/Analysis/ScalarEvolution.cpp +++ b/lib/Analysis/ScalarEvolution.cpp @@ -3367,8 +3367,8 @@ const SCEV *ScalarEvolution::createSCEV(Value *V) { // If C is a single bit, it may be in the sign-bit position // before the zero-extend.
