;;; 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.
