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