yesterday i was thinking about a way for interpretting assembly code of ARM (and maybe other architectures) while defining a grammar for its assembly.
This way it will be possible to embed parrot on a debugger and let't interact between the code and the debugger implementing in this way a pseudo-assembly- language for multiple architectures. The only thing that will be needed is the hardware interaction that can be extended with libraries and so, but atm i'm just interested on interpretting a sequence of opcodes and emulate them. Registers can be directly mapped into parrot registers and atm i'm only thinking on supporting text-based assembly, binary one can be added later. Here my questions: I think it would be rather simple to do it, but i don't have the skills yet for doing it. What's the 'easiest' language to start working on as a template? It is possible to define a binary grammar or i should write a parser for it in pure parrot and passing this code to a function that interprets a one line of assembly code. Should be better to implement everything in parrot instead of using a grammar? PD: I was trying to implement some hooks on the exception layer, but I saw that the interface it's not yet defined and I'll wait for it to continue this work. Thanks! --pancake
