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) Add support for mudflap, a pointer use checking library Allow for multiple versions to be emerged at once for same CTARGET 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 Run the testsuite and install the results (requires FEATURES=test) Build support for various sanitizer functions (ASAN/TSAN/etc...) Build support for virtual table verification (a C++ hardening feature) cpe:/a:gnu:gcc dgcc
