The shift_add_check_overflow and shift_add_check_overflow_tuple functions are re-written to be more efficient and to make use of the CheckedAdd instrinsic instead of manually checking for integer overflow. * The invokation leading_zeros() is removed and replaced with simple integer comparison. The leading_zeros() method results in a ctpop LLVM instruction and it may not be efficient on all architectures; integer comparisons, however, are efficient on just about any architecture. * The methods lose the ability for the caller to specify a particular shift value - that functionality wasn't being used and removing it allows for the code to be simplified. * Finally, the methods are renamed to add_bytes_to_bits and add_bytes_to_bits_tuple to reflect their very specific purposes. |

This is a preliminary version of the Rust compiler, libraries and tools Source layout: librustc/ The self-hosted compiler libstd/ The standard library (imported and linked by default) libextra/ The "extras" library (slightly more peripheral code) libsyntax/ The Rust parser and pretty-printer rt/ The runtime system rt/rust_*.cpp - The majority of the runtime services rt/isaac - The PRNG used for pseudo-random choices in the runtime rt/bigint - The bigint library used for the 'big' type rt/uthash - Small hashtable-and-list library for C, used in runtime rt/sync - Concurrency utils rt/util - Small utility classes for the runtime. rt/vg - Valgrind headers rt/msvc - MSVC support rt/linenoise - a readline-like line editing library test/ Testsuite test/compile-fail - Tests that should fail to compile test/run-fail - Tests that should compile, run and fail test/run-pass - Tests that should compile, run and succeed test/bench - Benchmarks and miscellanea test/pretty - Pretty-printer tests test/auxiliary - Dependencies of tests compiletest/ The test runner librustpkg/ The package manager and build system librusti/ The JIT REPL librustdoc/ The Rust API documentation tool llvm/ The LLVM submodule libuv/ The libuv submodule rustllvm/ LLVM support code libfuzzer/ A collection of fuzz testers etc/ Scripts, editor support, misc
