test/Transforms/RewriteStatepointsForGC/gc_relocate_creation.ll

; RUN: opt %s -rewrite-statepoints-for-gc -S 2>&1 | FileCheck %s
; This test is to verify gc.relocate can handle pointer to vector of
; pointers (<2 x i32 addrspace(1)*> addrspace(1)* in this case).
; The old scheme to create a gc.relocate of <2 x i32 addrspace(1)*> addrspace(1)*
; type will fail because llvm does not support mangling vector of pointers.
; The new scheme will create all gc.relocate to i8 addrspace(1)* type and
; then bitcast to the correct type.
