/* 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.

produces a valid time difference. */
