[llvm-dev] accessing subwords in memory

[Preston Briggs via llvm-dev]

I'm targeting a machine that can only load and store aligned 64-bit words,
but I'd like to be able to pack 8-, 16-, and 32-bit values into these words.
Loads will require various shifts and masks; stores are more complicated.
Does LLVM provide any support for such things?
Is there an example target I can look at for ideas?

Thanks,
Preston
