| +/* Timing variables are used to measure elapsed time in various
|
| + portions of the compiler. Each measures elapsed user, system, and
|
| + wall-clock time, as appropriate to and supported by the host
|
| + system.
|
| +
|
| + Timing variables are defined using the DEFTIMEVAR macro in
|
| + timevar.def. Each has an enumeral identifier, used when referring
|
| + to the timing variable in code, and a character string name.
|
| +
|
| + Timing variables can be used in two ways:
|
| +
|
| + - On the timing stack, using timevar_push and timevar_pop.
|
| + Timing variables may be pushed onto the stack; elapsed time is
|
| + attributed to the topmost timing variable on the stack. When
|
| + another variable is pushed on, the previous topmost variable is
|
| + `paused' until the pushed variable is popped back off.
|
| +
|
| + - As a standalone timer, using timevar_start and timevar_stop.
|
| + All time elapsed between the two calls is attributed to the
|
| + variable.

|
