How does that work? I see static void nvptx_file_start (void) { fputs ("// BEGIN PREAMBLE\n", asm_out_file); fputs ("\t.version\t3.1\n", asm_out_file); fputs ("\t.target\tsm_30\n", asm_out_file); fprintf (asm_out_file, "\t.address_size %d\n", GET_MODE_BITSIZE (Pmode)); fputs ("// END PREAMBLE\n", asm_out_file); } which I'd guess means the PTX code can be executed in sm_30 and newer only anyway.
