From 541ed9fd02ea48d2739f4a9dd681ba2d5da26886 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Wed, 21 Jan 2009 20:32:55 +0000 Subject: Do not use host floating point types when emitting ASCII IR; loading and storing these can change the bits of NaNs on some hosts. Remove or add warnings at a few other places using host floating point; this is a bad thing to do in general. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62712 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/APFloat.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib/Support/APFloat.cpp') diff --git a/lib/Support/APFloat.cpp b/lib/Support/APFloat.cpp index c296770385..d8d414d7ea 100644 --- a/lib/Support/APFloat.cpp +++ b/lib/Support/APFloat.cpp @@ -599,7 +599,8 @@ APFloat::copySignificand(const APFloat &rhs) } /* Make this number a NaN, with an arbitrary but deterministic value - for the significand. */ + for the significand.
