LLVM ARM v6 backend is in fairly good shape. Even the JIT passes nearly the entire llvm test suite. There are some known missing bits: 1. Exception handling 2. Atomic Not sure: 3. Debugging support (should be trivial to hook up if it's not done) Also the thumb backend is not awesome. Its performance is not great.

Hi, the ARM backend lacks some stuff like support for atomic intrinsics. I learned the hard way (crash). Lately I was told that the ARM backend of LLVM is generally in its early stages of development. I would like to know more about this. Which stuff is missing, known to be unstable and the like. Thanks in advance for taking the time. Regards Robert -------------- next part -------------- A
