[LLVMdev] Encoding instructions with inconsistent formats
I'm attempting to implement codegen support for the AVR ST/LD
<http://www.atmel.com/webdoc/avrassembler/avrassembler.wb_ST.html> family

The binary encoding is not particularly consistent -- take a look at this
table of variants of LD, along with their machine code representation:
# load 8 bits from pointer register X into general purpose Rd
