static void replace_str_in_buf ( )
static 
   Functions for pretty printing of CFG.  
   FIXME: Using pretty-print here could simplify this stuff.  
   Replace all occurencies of STR1 to STR2 in BUF.
   The BUF must be large enough to hold the result.  
             Copy the rest of buf and '\0'.  
             Shift str by DIFF chars.  
             Copy str2.
static void restore_dump ( )
static 
   Restore previously switched dump.

void sel_debug_cfg ( void  ) 
   Debug a cfg region with default flags.
void sel_debug_cfg_1 ( ) 
   Debug a cfg region with FLAGS.
static void sel_dump_cfg_1 ( )
static 
   Dump a cfg region to the file specified by TAG honoring flags.
   The file is created by the function.
static void sel_dump_cfg_2 ( )
static 
   Dump a cfg region to the dot file F honoring FLAGS.  
                 For simplicity, we dump notes from note_list in reversed order
                 to that what they will appear in the code.
static void sel_dump_cfg_edge ( )
static 
   Dump E to the dot file F.
static void sel_dump_cfg_insn ( )
static 
   Dump INSN with FLAGS.

References sched_dump_to_dot_p, and switch_dump().

static void sel_prepare_string_for_dot_label ( )
static 
   Replace characters in BUF that have special meaning in .dot file.
   Similar to pp_write_text_as_dot_label_to_stream.
void sel_print ( ) 
   This function acts like printf but dumps to the sched_dump file.

const char* sel_print_insn ( ) 
   Pretty print INSN.  This is used as a hook.  
     '+' before insn means it is a new cycle start and it's not been
     scheduled yet.  '>' - has been scheduled.

int dump_expr_flags = DUMP_EXPR_ALL
static 
   Default flags for dumping expressions.
int dump_flist_insn_flags
static
Initial value:
(DUMP_INSN_UID | DUMP_INSN_BBN
| DUMP_INSN_SEQNO)
   Controls how insns from a fence list should be dumped.
int dump_insn_rtx_flags = DUMP_INSN_RTX_UID | DUMP_INSN_RTX_PATTERN
static 
   Functions for dumping instructions, av sets, and exprs.  
   Default flags for dumping insns.
int dump_vinsn_flags
static
Initial value:
(DUMP_VINSN_INSN_RTX | DUMP_VINSN_TYPE
| DUMP_VINSN_COUNT)
   Default flags for dumping vinsns.
FILE* saved_sched_dump = NULL
static 
   The variable used to hold the value of sched_dump when temporarily
   switching dump output to the other source, e.g. the .dot file.

Referenced by switch_dump().

bool sched_dump_to_dot_p = false 
   When this flag is on, we are dumping to the .dot file.
   When it is off, we are dumping to log.
   This is useful to differentiate formatting between log and .dot
   files.
