Subject: [PATCH, libgfortran]: Use __builtin_ia32_{stmxcsr,ldmxcsr} intrinsics in config/fpu-i387.h

Hello!

This patch substitutes volatile asms with equivalent intrinsics.

2012-09-05  Uros Bizjak  <ubizjak@gmail.com>

	* config/fpu-387.h (set_fpu): Use __builtin_ia32_stmxcsr and
	__builtin_ia32_ldmxcsr intrinsics.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline an 4.7 branch.

Uros.
