toolchain@gentoo.org Gentoo Toolchain Project Useful only when building GCJ, this enables Abstract Window Toolkit (AWT) peer support on top of GTK+ Support the Cilk Plus language (C/C++ based languages for parallel programming) Enable support for the D programming language Enable fixed-point arithmetic support for MIPS targets in gcc (Warning: significantly increases compile time!) Build the GCC Go language frontend. Add support for the framework for loop optimizations based on a polyhedral intermediate representation 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. Build SSP support into a dedicated library rather than use the code in the C library (DO NOT ENABLE THIS IF YOU DON'T KNOW WHAT IT DOES) Enable support for Intel Memory Protection Extensions (MPX) Add support for mudflap, a pointer use checking library Disable PIE support (NOT FOR GENERAL USE) Disable SSP support (NOT FOR GENERAL USE) Build support for the Objective C code language Build support for the Objective C++ language Build support for the Objective C code language Garbage Collector Build GCC using Profile Guided Optimization (PGO) Run the testsuite and install the results (requires FEATURES=test) Build support for various sanitizer functions (ASAN/TSAN/etc...) Build packages with stack smashing protector on by default Build support for virtual table verification (a C++ hardening feature) cpe:/a:gnu:gcc dgcc
