; Check that abs.[ds] is selected and does not depend on -enable-no-nans-fp-math
; They obey the Has2008 and ABS2008 configuration bits which govern the
; conformance to IEEE 754 (1985) and IEEE 754 (2008). When these bits are not
; present, they confirm to 1985.
; 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).
