yaxpeax-avr

AVR decoders implemented as part of the yaxpeax project. Implements traits provided by yaxpeax-arch.

Known "issues"

• The brbc and brbs instructions are displayed as their equivalent pseudo-instructions, based on the bit they test: brbc 0, label becomes brsh label. In this case specifically, brcc also exists (and is identical), however brsh will be displayed.
• Target specification is limited to enabling/disabling support for 16-bit sts and lds instructions (as they can collide with other instructions cores with support for them don't have). Valid instructions (even if they might be unsupported by a core) are never rejected. Bytes which don't resemble an instruction from any instruction set subset are still invalid.
