Thanks!


If nvptx offloading compilation is enabled in addition to GCN, the former ICEs:

     during RTL pass: final
     [...]/libgomp.c/interop-hsa.c: In function 'get_kernel_ptr':
     [...]/libgomp.c/interop-hsa.c:34:1: internal compiler error: RTL check: 
expected code 'subreg', have 'reg' in nvptx_print_operand, at 
config/nvptx/nvptx.cc:3082


...


Regardless of the issue that nvptx offloading compilation probably shouldn't
ICE, the 'asm' insert clearly is valid for GCN only.


Can you file a PR to eventually fix this ice-on-invalid-code issue?
