clang - Use Clang compiler instead of GCC
cpu_flags_arm_neon - Use the NEON (ASIMD) instruction set
debug - Enable assertions to allow for easier debugging of programs that link to spidermonkey -- note this will often crash software on regular end-user systems
jit - Enable just-in-time compilation for improved performance. May prevent use of some PaX memory protection features in Gentoo Hardened.
lto - Enable Link Time Optimization (LTO)
test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
