; The instruction marked <<<LeakyInst>>> is copied into the GPUModule,

; the host, i.e., MemRef_arr becomes polly.access.cast.MemRef_arr. Since the
|
|
; instruction is annotated with a DILocation, copying the instruction also copies
|
|
; the metadata into the GPUModule. This stops codegenerating the ptx_kernel by
|
|
; failing the verification of the Module in GPUNodeBuilder::finalize, due to the
|
|
; copied DICompileUnit not being listed in a llvm.dbg.cu which was neither copied
|

; nor created.

|

; https://reviews.llvm.org/D35630 removes this debug metadata before the

; instruction is copied to the GPUModule.
