; Check that abs.[ds] is only selected for mips32r6 or mips64r6 when no
; additional options are passed. For revisions prior mips32r6 and mips64r6,
; abs.[ds] does not generate the correct result when working with NaNs, and
; should be explicitly enabled with -enable-no-nans-fp-math or +abs2008 options.
; In 1985 mode, abs.[ds] are arithmetic (i.e. they raise invalid operation
; exceptions when given NaN's). In 2008 mode, they are non-arithmetic (i.e.
; they are copies and don't raise any exceptions).
