;;; Test ‘frem’ Instruction
;;;
;;; Syntax:
;;;   <result> = frem [fast-math flags]* <ty> <op1>, <op2> ; yields ty:result
;;;
;;; Overview:
;;;   The ‘frem’ instruction returns the remainder from the division of its two
;;;   operands.
;;;
;;; Arguments:
;;;   The two arguments to the ‘frem’ instruction must be floating-point or
;;;   vector of floating-point values. Both arguments must have identical types.
;;;
;;; Semantics:
;;;   The value produced is the floating-point remainder of the two operands.
;;;   This is the same output as a libm ‘fmod’ function, but without any
;;;   possibility of setting errno. The remainder has the same sign as the
;;;   dividend. This instruction is assumed to execute in the default
;;;   floating-point environment. This instruction can also take any number
;;;   of fast-math flags, which are optimization hints to enable otherwise
;;;   unsafe floating-point optimizations:
;;;
;;; Example:
;;;
;;;   <result> = frem float 4.0, %var ; yields float:result = 4.0 % %var
;;;
;;; Note:
;;;   We test only float/double/fp128.
;;;   We have no way to generated frem from C source code, so convert fdiv
;;;   to frem by using sed program.
