Michael Meissner - Dec. 2, 2011, 5:23 p.m.
I committed this patch.  It fixes a thinko I had in the builtin support that I
committed on November 29th.  I had used the wrong field for figuring out the
attributes, and it meant that started failing
since __builtin_recipdiv and __builtin_recipdivf were not considered const
functions if -ffast-math was used.

	PR target/51390
	* config/rs6000/rs6000.c (def_builtin): Use the correct field to
	figure out the function's attributes.
	(struct builtin_description): Mark mask field as const since we no
	longer need to modify it for SPE and PAIRED builtins.
