The LLVM project recently released version 2.8, and updated the SVN tree version to 2.9svn, obsoleting the simple check for 'llvm-config --version' returning 2.8svn. With this commit we instead check for the substrings 2.8 and 2.9 in the output of 'llvm-config --version', since we (currently) support both the svn and released varieties of those versions. A stable release also complicates our check for the ocaml bindings. Previously we looked in `llvm-config --libdir`/ocaml which is appropriate for local compiles, but distribution packagers are likely to put the bindings in the default search path, e.g. /usr/lib/ocaml/llvm. We now fall back to trying variations on the standard library path returned by 'ocamlc -config' if we don't find it under 'llvm-config --libdir'. With this change, rust builds against LLVM 2.8 as packaged in Ubuntu 10.10 as well as LLVM 2.9svn compiled locally. (cherry picked from commit b606b65756f087c403180abd5418fe7dce469758)
This is preliminary version of the Rust compiler.
Source layout:
boot/ The bootstrap compiler
boot/README - More-detailed guide to it.
boot/fe - Front end (lexer, parser, AST)
boot/me - Middle end (resolve, check, layout, trans)
boot/be - Back end (IL, RA, insns, asm, objfiles)
boot/util - Ubiquitous helpers
boot/llvm - LLVM-based alternative back end
boot/driver - Compiler driver
comp/ The self-hosted compiler (doesn't exist yet)
comp/* - Same structure as in boot/
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,util} - Small utility classes for the runtime.
test/ Testsuite (for both bootstrap and self-hosted)
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
Please be gentle, it's a work in progress.
