Benoit Jacob	949f14e1e4	no, this wasn't equivalent to ei_pload at all, after all!	2009-12-15 07:43:05 -05:00
Benoit Jacob	805eb9cc8b	Gael, who is a man of few words^Winstructions, is right, as usual.	2009-12-15 06:50:40 -05:00
Benoit Jacob	4948448939	*use scalar instructions, packet not needed here ... *remove unused var warning	2009-12-14 23:13:54 -05:00
Benoit Jacob	d02eccf584	add SSE path for Matrix4f inverse, taken from Intel except that we do a kosher ... division instead of RCPPS-followed-by-Newton-Raphson. The rationale for that is that elsewhere in Eigen we dont allow ourselves this approximation (which throws 2 bits of mantissa), so there's no reason we should allow it here.	2009-12-14 22:47:14 -05:00
