Macro Definition Documentation

◆ DEFTIMEVAR

#define DEFTIMEVAR ( identifier__,
name__ )    identifier__,
An enumeration of timing variable identifiers.  Constructed from
the contents of timevar.def.   

Enumeration Type Documentation

◆ timevar_id_t

Enumerator
TV_NONE 
TIMEVAR_LAST 

Function Documentation

◆ print_time()

void print_time ( const char * str,
long total )
extern
Prints a message to stderr stating that time elapsed in STR is
TOTAL (given in microseconds).   

References all_time, and ggc_alloc().

◆ timevar_cond_start()

bool timevar_cond_start ( timevar_id_t timevar)
extern
Conditionally start timing TIMEVAR independently of the timing stack.
If the timer is already running, leave it running and return true.
Otherwise, start the timer and return false.
Elapsed time until the corresponding timevar_cond_stop
is called for the same timing variable is attributed to TIMEVAR.   

References timer::cond_start(), and g_timer.

◆ timevar_cond_stop()

void timevar_cond_stop ( timevar_id_t timevar,
bool running )
extern
Conditionally stop timing TIMEVAR.  The RUNNING parameter must come
from the return value of a dynamically matching timevar_cond_start.
If the timer had already been RUNNING, do nothing.  Otherwise, time
elapsed since timevar_cond_start was called is attributed to it.   

References timer::cond_stop(), g_timer, and ggc_alloc().

◆ timevar_init()

void timevar_init ( void )
extern
Initialize timing variables.

Variable Documentation

◆ g_timer

timer* g_timer
extern
The singleton instance of timing state.

This is non-NULL if timevars should be used.  In GCC, this happens with
the -ftime-report flag.  Hence this is NULL for the common,
needs-to-be-fast case, with an early reject happening for this being
NULL.

◆ timevar_ggc_mem_total
