; This test verifies whether cyclic call graph is properly handled by CastToGASAnalysis.
; Here is a call graph for below test:
; kernelA kernelB
; / /
; f0 f2
; / \
; / /
; | /
; f1
; Expecting that call graph analysis will properly lead to optimizing all load and store instructions
; within functions accesible from kernelA, since kernelA uses only global memory.
; Memory operations accesible from kernelB should not be optimized, since it uses both global and
; local memory.
