so i want a self hosted bytecode compiler, i.e. the bytecode interpreter has a bytecode blob it can interpret that is the bytecode compiler which can then compile input programs into bytecode so the interpreter can run them

Good news everyone! 🎉 After two years of R&D, we've finally merged the Bytecode DSL into master! Truffle now generates bytecode interpreters from AST-like specifications for you. ASTs are dead, long live bytecodes!

That kind of thing isn't obvious from bytecode, and usually requires a higher level understanding of a codebase's domain

hi does anyone still care about my hermes bytecode patching
i can either create an AST walking reference interpreter that runs the bytecode compiler on itself to produce the bytecode blob or i can use my already existing IR->C compiler to compile the bytecode compiler to C and compile its own IR to a bytecode blob that way
and i'm not sure which is better

like it seems to me that an architecture which is word input --> translation layer --> bytecode vocabulary LLM --> translation layer --> word output would be possible.
I'm extremely intrigued by the space where LLM-driven development intersects with formal methods and think that this might be where the magic happens. Skeptical that LLMs barfing a bunch of hopefully-this-works python is a fruitful path forward

Here's a fun blog post about bytecode VMs in surprising places.
Mildly hot take of mine: a bytecode VM in a GPU kernel is not as bad of an idea as one might think, and in some cases it can actually be the best solution. Fun examples in thread:

everything is a bytecode-targetable virtual machine if you look at it sideways.
JBIG2 image decompression? virtual machine.
x86 mov instruction? virtual machine.
truetype fonts? virtual machine.
Magic: The Gathering? believe it or not, also virtual machine.
