This looks good, thanks for proving me wrong. Which OSX version is this? I've had troubles with denormals in fat binaries in the past (OSX 10.5). It turned out that the preprocessor didn't pass architecture defines when preprocessing for multiple architectures.

tested on both 10.6 and 10.9

$ sw_vers ProductName: Mac OS X ProductVersion: 10.6.8 BuildVersion: 10K549 $ cc --version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

resp.

$ sw_vers ProductName: Mac OS X ProductVersion: 10.9.5 BuildVersion: 13F34 $ cat vers.txt Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn) Target: x86_64-apple-darwin13.4.0 Thread model: posix

Today I could test the same on OSX 10.5 with Xcode 3.1.4 installed and it seems to work fine here as well (__i386__ resp. __x86_64__ defined in the case of fat binaries).

$ sw_vers ProductName: Mac OS X ProductVersion: 10.5.8 BuildVersion: 9L31a

$ cc --version i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5493)

Only thing I can't test now is with gcc < 4 but so far my 'issue' couldn't be reproduced, fortunately.
