Description Mark Hahnenberg 2014-06-25 13:40:31 PDT
Currently we use C-style bit fields for a number of member variables in Structure to save space. This makes it difficult to load these fields in the JIT. We should instead use our own bitfield format to make it easy to load and test these variables in JIT code.
