The builder functions in trans_build now look at an 'unreachable' flag in the block context and don't generate code (returning undefined placeholder values) when this flag is set. Threading the unreachable flag through context still requires some care, but this seems a more sane approach than re-checking for terminated blocks throughout the compiler. When creating a block, if you use its closest dominator as parent, the flag will be automatically passed through. If you can't do that, because the dominator is a scope block that you're trying to get out of, you'll have to do something like this to explicitly pass on the flag: if bcx.unreachable { Unreachable(next_cx); } Closes #949. Closes #946. Closes #942. Closes #895. Closes #894. Closes #892. Closes #957. Closes #958. |

This is preliminary version of the Rust compiler. Source layout: comp/ The self-hosted compiler lib/ The standard library rustllvm/ LLVM support code 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/libuv - The library used for async IO in the runtime rt/{sync,util} - Small utility classes for the runtime. 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 Please be gentle, it's a work in progress.
