-; 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).
