JUST-IN-TIME COMPILER SUPPORT
Just-in-time compiler support is included in the build by
specifying
--enable-jit
This support is available only for certain hardware
architectures. If this option is set for an unsupported
architecture, a compile time error occurs. See the pcrejit
documentation for a discussion of JIT usage. When JIT support is
enabled, pcregrep automatically makes use of it, unless you add
--disable-pcregrep-jit
to the "configure" command.
