Global USE flag

Add support for Perl Compatible Regular Expressions

Packages describing “pcre-jit” as local USE flag

Package “pcre-jit” Flag Description
app-emulation/aranym Build Just-In-Time compiler variant with increased performance
dev-haskell/highlighting-kate Use the pcre-light library instead of regex-pcre-builtin.
dev-lang/moarvm Enable Just-In-Time-Compiler. Has no effect except on AMD64 and Darwin.
dev-vcs/git Enable JIT for pcre
net-analyzer/sarg Enable support for regular expressions in the hostalias file through dev-libs/libpcre
net-im/prosody Use LuaJIT instead of vanilla Lua
net-proxy/haproxy Use JIT support for PCRE2
net-wireless/kismet Build with pcre support
sys-devel/gcc Enable libgccjit so other applications can embed gcc for Just-In-Time compilation. This will slow down the compiler a bit as it forces all of the toolchain to be shared libs.
www-apache/mod_security Add support for the PCRE Just-in-Time optimisation, as enabled by dev-libs/libpcre with jit USE flag enabled. Might not be available on hardened systems.
www-apps/cgit If the lua flag is enabled, jit uses LuaJIT instead of vanilla Lua
www-servers/nginx Enable JIT for pcre
