The documentation for PCRE, supplied in the "doc" +directory, is distributed under the same terms as the software itself. + +The basic library functions are written in C and are freestanding. Also +included in the distribution is a set of C++ wrapper functions, and a +just-in-time compiler that can be used to optimize pattern matching.

Nevertheless, some regular expressions can cause +it to recurse to a great depth. I was writing for Unix, so I just let it call +itself recursively. This uses the stack for saving everything that has to be +saved for a recursive call. On Unix, the stack can be large, and this works +fine. + +It turns out that on some non-Unix-like systems there are problems with +programs that use a lot of stack. (This despite the fact that every last chip +has oodles of memory these days, and techniques for extending the stack have +been known for decades.) So.... + +There is a fudge, triggered by defining NO_RECURSE, which avoids recursive +calls by keeping local variables that need to be preserved in blocks of memory +obtained from malloc() instead instead of on the stack. Macros are used to +achieve this so that the actual code doesn't look very different to what it +always used to. + +The original heap-recursive code used longjmp(). However, it seems that this +can be very slow on some operating systems. Following a suggestion from Stan +Switzer, the use of longjmp() has been abolished, at the cost of having to +provide a unique number for each call to RMATCH. There is no way of generating +a sequence of numbers at compile time in C. I have given them names, to make +them stand out more clearly. + +Crude tests on x86 Linux show a small speedup of around 5-8%. However, on +FreeBSD, avoiding longjmp() more than halves the time taken to run the standard +tests. Furthermore, not using longjmp() means that local dynamic variables +don't have indeterminate values; this has meant that the frame size can be +reduced because the result can be "passed back" by straight setting of the +variable instead of being passed in the frame. +**************************************************************************** +***************************************************************************/ + +/* Numbers for RMATCH calls.

The basic blocks of regular expressions are condition checkers +whose execute different commands depending on the result of the condition check. +The relationship between the operators can be horizontal (concatenation) and +vertical (sub-expression) (See struct fallback_common for more details). + + 'ab' - 'a' and 'b' regexps are concatenated + 'a+' - 'a' is the sub-expression of the '+' operator + +The condition checkers are boolean (true/false) checkers. Machine code is generated +for the checker itself and for the actions depending on the result of the checker. +The 'true' case is called as the hot path (expected path), and the other is called as +the 'fallback' path. Branch instructions are expesive for all CPUs, so we avoid taken +branches on the hot path. + + Greedy star operator (*) : + Hot path: match happens. + Fallback path: match failed. + Non-greedy star operator (*?) : + Hot path: no need to perform a match. + Fallback path: match is required. + +The following example shows how the code generated for a capturing bracket +with two alternatives. Let A, B, C, D are arbirary regular expressions, and +we have the following regular expression: + + A(B|C)D + +The generated code will be the following: + + A hot path + '(' hot path (pushing arguments to the stack) + B hot path + ')' hot path (pushing arguments to the stack) + D hot path + return with successful match + + D fallback path + ')' fallback path (If we arrived from "C" jump to the fallback of "C") + B fallback path + C expected path + jump to D hot path + C fallback path + A fallback path + + Notice, that the order of fallback code paths are the opposite of the fast + code paths. In this way the topmost value on the stack is always belong + to the current fallback code path. The fallback code path must check + whether there is a next alternative. If so, it needs to jump back to + the hot path eventually. Otherwise it needs to clear out its own stack + frame and continue the execution on the fallback code paths. +*/ + +/* +Saved stack frames: + +Atomic blocks and asserts require reloading the values of local variables +when the fallback mechanism performed.
