Description
isaspec is tool to describe an instruction set in xml, and generate assembler and disassembler from that single description. It is currently used by freedreno (ir3), with a WIP MR for etnaviv conversion. It has a number of interesting features do deal with (at least slightly) weird instruction sets:
- the base construct is a "bitset", which can be an entire instruction, or used as a field type in a larger bitset
- flexible override and display mechanism, to deal with instructions where some bits have completely different meaning depending on other bit(s) in the instruction, to deal with mnemonics, etc
- inheritance ("extends") to reduce duplication between groups of similar instructions
