; Verify that we accept calls to variables in the program AS:
; RUN: llvm-as -data-layout "P40" %s -o - | llvm-dis - | FileCheck %s
; CHECK: target datalayout = "P40"

; We should get a sensible error for a non-program address call:
; RUN: not llvm-as -data-layout "P39" %s -o /dev/null 2>&1 | FileCheck %s -check-prefix ERR-AS39
; ERR-AS39: error: '%fnptr' defined with type 'void (i16) addrspace(40)*' but expected 'void (i16) addrspace(39)*'

; And also if we don't set a custom program address space:
; RUN: not llvm-as %s -o /dev/null 2>&1 | FileCheck %s -check-prefix ERR-AS0
; ERR-AS0: error: '%fnptr' defined with type 'void (i16) addrspace(40)*' but expected 'void (i16)*'
