From 5c251169cd297f113337afe7034f8b47bb49b99d Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Fri, 20 Feb 2015 15:11:55 +0000 Subject: [PATCH] Constants.cpp: Only read 32 bits for float. Otherwise we'll discard the wrong half of a uint64_t on big-endian systems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230016 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/IR/Constants.cpp | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/lib/IR/Constants.cpp b/lib/IR/Constants.cpp index 1c93265c79d..0bf61a77ea2 100644 --- a/lib/IR/Constants.cpp +++ b/lib/IR/Constants.cpp @@ -2715,16 +2715,19 @@ uint64_t ConstantDataSequential::getElementAsInteger(unsigned Elt) const { /// type, return the specified element as an APFloat.
