How about describing it as Equivalent to @samp{op0 = op1 * copysign (1.0, op2)}: store a value with the magnitude of operand 1 and the sign of operand 2 into operand 0. All operands have mode @var{m}, which is a scalar or vector floating-point mode. This pattern is not allowed to @code{FAIL}.That works for me, updated patch attached. OK for trunk?
Yes, this is fine. :-) -Sandra
