[PATCH] Re: [PATCH] x86: disable use of paddq and psubq without SSE2 support

[Jan Beulich]

This fixes the 32-bit x86 MMX testsuite failures.

Bootstrapped and tested on i686-pc-linux-gnu.

2005-12-09  Jan Beulich  <jbeulich@novell.com>

	* config/i386/mmintrin.m (_mm_add_si64, _mm_sub_si64):
Conditionalize
	upon __SSE2__.
