hi all, these are the last passes:
NEXT_PASS (pass_stack_regs); ////////// last pass to generate VCG file NEXT_PASS (pass_compute_alignments); NEXT_PASS (pass_duplicate_computed_gotos); NEXT_PASS (pass_variable_tracking); NEXT_PASS (pass_free_cfg); NEXT_PASS (pass_machine_reorg); NEXT_PASS (pass_purge_lineno_notes); NEXT_PASS (pass_cleanup_barriers); NEXT_PASS (pass_delay_slots); NEXT_PASS (pass_split_for_shorten_branches); NEXT_PASS (pass_convert_to_eh_region_ranges); NEXT_PASS (pass_shorten_branches); NEXT_PASS (pass_set_nothrow_function_flags); NEXT_PASS (pass_final); ///////// translating to assembly (-->binary) the pass_stack_regs is the last one which generates a vcg file (graph of flow). the pass_final is of course the one which translates to assembly, therefore after it I assume the flow of the code does not change. my question is whether I can use the flow dumped by pass_stack_regs pass and assume it is legal as the flow of the real binary ? of do any of the passes between them change the flow ? thank you all sunzir
