; This test checks how a function pointer in a dedicated addr space would be
; translated with and without -spirv-emit-function-ptr-addr-space option.
; Expected behaviour:
; No option is passed to the forward translation stage - no CodeSectionINTEL storage class in SPIR-V
; The option is passed to the forward translation stage - CodeSectionINTEL storage class is generated
; No option is passed to the reverse translation stage - function pointers are in private address space
; The option is passed to the reverse translation stage - function pointers are in addrspace(9)
;
; Overall IR generation is tested elsewhere, here checks are very simple
