Enable just-in-time compilation for improved performance. May prevent use of some PaX memory protection features in Gentoo Hardened.
|Package||“jit” Flag Description|
|app-emulation/aranym||Build Just-In-Time compiler variant with increased performance|
|net-im/prosody||Use LuaJIT instead of vanilla Lua|
|dev-lang/moarvm||Enable Just-In-Time-Compiler. Has no effect except on AMD64 and Darwin.|
|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.|
|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.|
