| ; The instruction marked <<<LeakyInst>>> is copied into the GPUModule, |
| ; with changes only to the parameters to access data on the device instead of |
| ; 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. |
