/*

* The "internal use only" fields in regexp.h are present to pass info from
|
|
* compile to execute that permits the execute phase to run lots faster on
|
|
* simple cases. They are:
|
|
*
|
|
* regstart char that must begin a match; '\0' if none obvious
|
|
* reganch is the match anchored (at beginning-of-line only)?
|
|
* regmust string (pointer into program) that match must include, or NULL
|
|
* regmlen length of regmust string
|
|
*
|
|
* Regstart and reganch permit very fast decisions on suitable starting points
|
|
* for a match, cutting down the work a lot. Regmust permits fast rejection
|
|
* of lines that cannot possibly match. The regmust tests are costly enough
|
|
* that regcomp() supplies a regmust only if the r.e. contains something
|
|
* potentially expensive (at present, the only such thing detected is * or +
|
|
* at the start of the r.e., which can involve a lot of backup). Regmlen is
|
|
* supplied because the test in regexec() needs it and regcomp() is computing
|
|
* it anyway.
