0aec6014 EB	148	/* Versions prior to 3.4.4 were not taking into account the word size for
	149	the 5 trapping arithmetic functions absv, addv, subv, mulv and negv. As
	150	a consequence, the si and di variants were always and the only ones emitted.
	151	To maintain backward compatibility, COMPAT_SIMODE_TRAPPING_ARITHMETIC is
	152	defined on platforms where it makes sense to still have the si variants
	153	emitted. As a bonus, their implementation is now correct. Note that the
	154	same mechanism should have been implemented for the di variants, but it
	155	turns out that no platform would define COMPAT_DIMODE_TRAPPING_ARITHMETIC
	156	if it existed. */
