Host-sized word type used to buffer unread bitstream data.
Declared in <llvm/Bitstream/BitstreamReader.h>
using word_t = size_t;This is the current data we have pulled from the stream but have not returned to the client. This is specifically and intentionally defined to follow the word size of the host machine for efficiency. We use word_t in places that are aware of this to make it perfectly explicit what is going on.
