Subject: [PATCH] Guard xmmintrin.h include so it is only used when necessary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The x86/SSE specific code for Flush-To-Zero is only used when
SSE_CORRECT_DENORMALS is not defined. Guarding the include allows the
code to compile on e.g. ARM.
