From fda2cce3bf04b530d87b551cf37a80f82074893d Mon Sep 17 00:00:00 2001 From: Brian Gaeke Date: Mon, 14 Jun 2004 06:33:19 +0000 Subject: [PATCH] Quick hack to get this file compiling again on Mac OS X. The right thing to do is write an autoconf macro that checks whether __isnan or isnan actually works **using the C++ compiler after #include **, instead of doing it the easy way with AC_CHECK_FUNCS(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14171 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/Local.cpp | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/lib/Transforms/Utils/Local.cpp b/lib/Transforms/Utils/Local.cpp index edb9742655a..e9ec6db069c 100644 --- a/lib/Transforms/Utils/Local.cpp +++ b/lib/Transforms/Utils/Local.cpp @@ -20,6 +20,14 @@ #include using namespace llvm; +#if defined(__POWERPC__) && defined(__APPLE_CC__) +// FIXME: Currently it seems that isnan didn't make its way into the Apple +// C++ headers, although it IS in the C headers (which confuses autoconf +// in a big way).
