This function is used to create a stack for use by the code compiled by the JIT
|
2014-11-28 13:46:16 +01:00
|
|
|
compiler. The first two arguments are a starting size for the stack, and a
|
|
|
|
|
maximum size to which it is allowed to grow. The final argument is a general
|
|
|
|
|
context, for memory allocation functions, or NULL for standard memory
|
|
|
|
|
allocation. The result can be passed to the JIT run-time code by calling
|
2014-10-21 18:33:30 +02:00
|
|
|
\fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern,
|
|
|
|
|
which can then be processed by \fBpcre2_match()\fP. If the "fast path" JIT
|
|
|
|
|
matcher, \fBpcre2_jit_match()\fP is used, the stack can be passed directly as
|
|
|
|
|
an argument. A maximum stack size of 512K to 1M should be more than enough for
|
|
|
|
|
any pattern. For more details, see the
