sel_dump_cfg_insn (insn_t insn, int flags)
Hi! This patch saves almost 19KB of .text (roughly 21% of sel-sched{,-dump}.c .text) and removes varargs macro while doing that (which don't have to be supported by pre-ISOC99 bootstrap compilers). Not that I care much about such bootstrap compilers, but having large inline expansion of this macro in almost 150 places when it is in code not enabled by default is strange (and sched_dump_to_dot_p is only true when invoking sel_debug_cfg{,_1} from the debugger). Invoking sel_debug_cfg{,_1} from the debugger ICEs for me though even before the patch, I probably don't know where is the right spot to invoke this function, so I haven't tested sel_print when creating the *.dot file, can one of the sel-sched authors please test that? 2010-06-14 Jakub Jelinek <jakub@redhat.com> PR bootstrap/44426 * sel-sched-dump.h (sel_prepare_string_for_dot_label): Remove prototype.
