; This test checks that OCL builtins preserve the type information for opaque
; pointer parameters in their mangling even when untyped pointers extension is enabled.
; Also check for the cases where the pointer parameter is used indirectly to emulate real-life usage.

; Instructions from OpenCL.std extended instruction set that have pointer arguments:
; Math extended instructions: fract, frexp, lgamma_r, modf, remquo, sincos
; Misc instructions: printf, prefetch (covered by separate tests)
