This section provides updates on these sub-projects. +DragonEgg: GCC front-ends, LLVM back-end +---------------------------------------- + +`DragonEgg <http://dragonegg.llvm.org/>`_ is a +`GCC plugin <http://gcc.gnu.org/wiki/plugins>`_ that replaces GCC's optimizers +and code generators with LLVM's. It works with gcc-4.5, 4.6, 4.7 and 4.8, can +target the x86-32/x86-64 and ARM processor families, and has been successfully +used on the Darwin, FreeBSD, KFreeBSD, Linux and OpenBSD platforms. It fully +supports Ada, C, C++ and Fortran. It has partial support for Go, Java, Obj-C +and Obj-C++. Note that gcc-4.6 is the best supported version, and that Ada in +particular doesn't work well with gcc-4.7 and newer. + +The `3.3 release <http://llvm.org/apt/>`_ has the following notable changes. + +- supports gcc-4.8 (requires gcc-4.8.1 or newer) +- object files can be written directly using LLVM's integrated assembler +- produces saner debug info +- bitfields can now contain arbitrary scalar types (useful for Ada) + + LLDB: Low Level Debugger ------------------------ |
