#define DEFTIMEVAR | ( | identifier__, | |
name__ ) |
An enumeration of timing variable identifiers. Constructed from the contents of timevar.def.
enum timevar_id_t |
|
extern |
Prints a message to stderr stating that time elapsed in STR is TOTAL (given in microseconds).
References all_time.
|
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.
|
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.

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.
