having a stream server isn't too difficult. you basically setup your obs to stream to another obs instance on another pc. and that pc then streams to other stuff. thats also how you can have different overlays for different broadcasts.

you're just copying instructions into a buffer and executing them

reposting so i dont have to scroll up each time
sage crag
you're just copying instructions into a buffer and executing them
int main() {
void (*fnptr)() = &&womp;
fnptr();
womp: __builtin_trap();
}
anyway compiler lets you do this
main:
push rax
lea rax, [rip + .Ltmp0]
call rax
.Ltmp0:

and it works 
nevermind, change to return 0; and

so i guess if you call a normal function pointer you get a prologue/epilogue unless you specifically ask for a naked function and if you just cast it like this then it takes it as is

i have no clue what any of this is
i just watched a couple youtube videos on compilers
opaque sigil
prologue/epilogue are some instructions that are used to setup registers
since yknow you use the same ones for everything
sage crag
ye
opaque sigil
so you first save them and then at the end revert them
olive sable
sure
sage crag
can be external to function if the function clobbers (or its uncertain if the function clobbers) and you need to save registers
via pop/push
olive sable
i see

for example, in this vm, it causes
because main needs to store these registers for c runtime

switch-case vm
tail-call vm
indirect goto vm (no pre-translation)
direct goto vm (pre-translation)
cursed jit vm (dont)
i might make a benchmark comparison for giggles
you can fit switch-case, the two gotos, and the cursed jit into one function with some macros
the tail-call vm is differently structured

for the cursed jit vm, its converting the bytecode into native code without doing any of the work of binary translation

for indirect and direct goto vms, its about getting the compiler to generate a jump table, which outperforms switch-case and tail-call based vms

sage crag
in principle have to do the same thing for translation based vm too
so if i implement it there, it should fall out naturally in the jit impl maybe
once i have imm storage
or something
tender river
fallback to standard vm execution on absolute jump
another problem is
to compute relative offsets in code you're translating you have to know them at translation time
solution
each translated opcode is fixed length, so you can do the following passes
- translate code, using dummy offsets, storing the current position every 1024 instructions (arbitrary number, memory vs performance tradeoff, maybe use 512 or even 256)
- go back and translate the offsets, use the "every 1024" for anchoring and then walk through opcodes to find the exact location
tender river
awa
tender river
complexity compared to standard vm is high
also
address translation is
platform dependent

i'd personally just
write two versions of every instruction
maybe write a script to mostly autogenerate it from c code
