LLVM 3.2 was branched last weekend and now the source packages for the first release candidate are ready for testing. Binary packages of 3.2-rc1 aren't available yet but will be available for major platforms/targets in the coming days.
LLVM 3.2-rc1 incorporates LLVM itself, Clang, Compiler-RT, the DragonEgg GCC plug-in, Polly, and the compiler test suite. Those wanting to help out testing this LLVM 3.2 development milestone can find details from the mailing list announcement. LLVM 3.2 should be officially released in mid-December.
