...h similar to the BigBlock allocator (i.e. the MIN algorithm), but extends it from basic blocks to the whole CFG of a function and does it at the SSA level. The implementation is available as part of the libFirm project. Another research project can be found here: http://www.contrib.andrew.cmu.edu/~jbauman/15745/ It seems to be based on LLVM's BigBlock and takes some inspiration from the paper mentioned above. In both cases, register allocators produce results that are quite comparable or even significantly better than LLVM's linear scan register allocator, in particular when it comes to the...

Hi all, I'd like to kill off the bigblock register allocator. Is anyone still using it? Cheers, Lang.
