Macro Definition Documentation
◆ DEFTIMEVAR
| #define DEFTIMEVAR | ( | identifier__, | |
| name__ ) |
◆ GGC_MEM_BOUND
| #define GGC_MEM_BOUND (1 << 20) |
The amount of memory that will cause us to report the timevar even if the time spent is not significant.

◆ nanosec_to_floating_sec
| #define nanosec_to_floating_sec | ( | NANO | ) |
Referenced by make_json_for_timevar_time_def(), timer::print(), and timer::print_row().
◆ percent_of
| #define percent_of | ( | TOTAL, | |
| SUBTOTAL ) |

Function Documentation
◆ get_time()
|
static |
See timevar.h for an explanation of timing variables.
Fill the current times into TIME, and define HAVE_WALL_TIME if there.
References timevar_time_def::ggc_mem, NULL, timevar_ggc_mem_total, and timevar_time_def::wall.
Referenced by timer::cond_start(), timer::cond_stop(), timer::make_json(), timer::pop_internal(), timer::print(), timer::push_internal(), timer::start(), and timer::stop().
◆ make_json_for_timevar_time_def()
| std::unique_ptr< json::object > make_json_for_timevar_time_def | ( | const timevar_time_def & | ttd | ) |
Create a json value representing this object, suitable for use in SARIF output.
References timevar_time_def::ggc_mem, make_unique(), nanosec_to_floating_sec, and timevar_time_def::wall.
Referenced by timer::make_json(), and timer::timevar_def::make_json().
◆ print_time()
| void print_time | ( | const char * | str, |
| long | total ) |
Prints a message to stderr stating that time elapsed in STR is TOTAL (given in microseconds).
References all_time.
◆ timevar_accumulate()
|
static |
Add the difference between STOP_TIME and START_TIME to TIMER.
References timevar_time_def::ggc_mem, and timevar_time_def::wall.
Referenced by timer::cond_stop(), timer::pop_internal(), timer::print(), timer::push_internal(), and timer::stop().
◆ timevar_cond_start()
| bool timevar_cond_start | ( | timevar_id_t | timevar | ) |
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 ) |
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(), and g_timer.
◆ timevar_diff()
|
static |
Get the difference between STOP_TIME and START_TIME.
References timevar_time_def::ggc_mem, and timevar_time_def::wall.
Referenced by timer::make_json().
◆ timevar_init()
| void timevar_init | ( | void | ) |
◆ timevar_start()
| void timevar_start | ( | timevar_id_t | timevar | ) |
Start timing TIMEVAR independently of the timing stack. Elapsed time until timevar_stop is called for the same timing variable is attributed to TIMEVAR.
References g_timer, and timer::start().
Referenced by symbol_table::compile(), compile_file(), do_compile(), global_decl_processing(), and toplev::start_timevars().
◆ timevar_stop()
| void timevar_stop | ( | timevar_id_t | timevar | ) |
Stop timing TIMEVAR. Time elapsed since timevar_start was called is attributed to it.
References g_timer, and timer::stop().
Referenced by symbol_table::compile(), compile_file(), do_compile(), and global_decl_processing().
