USE flags

• cxx - Build support for C++ (bindings, extra libraries, code generation, ...)
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
• doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• fortran - Add support for fortran
• hardened - Activate default security enhancements for toolchain (gcc, glibc, binutils)
• jit - Enable just-in-time compilation for improved performance. May prevent use of some PaX memory protection features in Gentoo Hardened.
• modula2
• multilib - On 64bit systems, if you want to be able to compile 32bit and 64bit binaries
• nls - Add Native Language Support (using gettext - GNU locale utilities)
• openmp - Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
• pch - Enable precompiled header support for faster compilation at the expense of disk space and memory
• pie - Build programs as Position Independent Executables (a security hardening technique)
• test - Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
• vanilla - Do not add extra patches which change default behaviour; DO NOT USE THIS ON A GLOBAL SCALE as the severity of the meaning changes drastically
• zstd - Enable support for ZSTD compression
