This adds two features: "packets", and "nvj". Enabling "packets" allows the compiler to generate instruction packets, while disabling it will prevent it and disable all optimizations that generate them. This feature is enabled by default on all subtargets. The feature "nvj" allows the compiler to generate new-value jumps and it implies "packets". It is enabled on all subtargets. The exception is made for packets with endloop instructions, since they require a certain minimum number of instructions in the packets to which they apply. Disabling "packets" will not prevent hardware loops from being generated. llvm-svn: 327302
Low Level Virtual Machine (LLVM) ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup.
