Subject: [PATCH, i386]: Define FP_TRAPPING_EXCEPTIONS

Hello!

Following aarch64 example, we can define FP_TRAPPING_EXCEPTIONS for x86, too.

2012-12-05  Uros Bizjak  <ubizjak@gmail.com>

        * config/i386/sfp-machine.h (FP_EX_ALL): Define.
	(FP_TRAPPING_EXCEPTIONS): Define.
	* config/i386/32/sfp-machine.h (FP_EX_SHIFT): Define.
	* config/i386/64/sfp-machine.h (FP_EX_SHIFT): Ditto.

Tested on x86_64-pc-linux-gnu {,-m32}.

If there are no objections, I will commit this patch to mainline SVN tomorrow.

Uros.
