#

for anyone else here

#

#

i need help debugging that

#

the compiler produces these list of instructions from the code above:

#

vm.Instruction{ .type = vm.Instruction.Type.LABEL, .values = { fib } }
vm.Instruction{ .type = vm.Instruction.Type.STORE, .values = { 0 } }
vm.Instruction{ .type = vm.Instruction.Type.LOAD, .values = { 0 } }
vm.Instruction{ .type = vm.Instruction.Type.PUSH, .values = { 2 } }
vm.Instruction{ .type = vm.Instruction.Type.LESS, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.NOT, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.IFJMP, .values = { 9 } }
vm.Instruction{ .type = vm.Instruction.Type.LOAD, .values = { 0 } }
vm.Instruction{ .type = vm.Instruction.Type.RET, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.LOAD, .values = { 0 } }
vm.Instruction{ .type = vm.Instruction.Type.PUSH, .values = { 1 } }
vm.Instruction{ .type = vm.Instruction.Type.SUB, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.CALL, .values = { fib } }
vm.Instruction{ .type = vm.Instruction.Type.LOAD, .values = { 0 } }
vm.Instruction{ .type = vm.Instruction.Type.PUSH, .values = { 2 } }
vm.Instruction{ .type = vm.Instruction.Type.SUB, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.CALL, .values = { fib } }
vm.Instruction{ .type = vm.Instruction.Type.ADD, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.RET, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.END_LABEL, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.PUSH, .values = { 2 } }
vm.Instruction{ .type = vm.Instruction.Type.CALL, .values = { fib } }
vm.Instruction{ .type = vm.Instruction.Type.LOG, .values = {  } }
vm.Instruction{ .type = vm.Instruction.Type.EXIT, .values = {  } }```

try adding

more debug logs as it's being run

#

somewhere a value isn't done incorrectly

i suspect around returning and passing that as a value to the add

#

it's hard to tell

#

hmm

#

I do not like the store instruction

#

fib(3)

manic bobcat Oct 17, 2023, 3:42 PM

#

This might be a problem with local scopes

#

You might treat all n as the same thing

#

And they are not

primal heath Oct 17, 2023, 3:42 PM

#

yea...

manic bobcat Oct 17, 2023, 3:42 PM

#

That's why I liked implementing knight-lang

#

It has no concept of local scope

#

Every variable is global

#

And functions don't take args (but they don't actually exist tho)

primal merlin Oct 17, 2023, 3:43 PM

#

the reason mine has been taking a while to get going is the bytecode requires you assign each variable name an id and finding out if it's global or local ahead of time

primal heath Oct 17, 2023, 3:44 PM

#

i dont like the store here

manic bobcat Oct 17, 2023, 3:44 PM

#

Popping would delete the argument

primal heath Oct 17, 2023, 3:44 PM

#

yeah sorry

#

i meant..

#

like

#

dont store maybe?

manic bobcat Oct 17, 2023, 3:45 PM

#

Probably

#

But keeping it on the stack also doesn't sound too easy

#

Since you'd need to understand when to swap or do stuff like under or rot

#

Coming from forth terms

primal heath Oct 17, 2023, 3:46 PM

#

call should do the store

manic bobcat Oct 17, 2023, 3:56 PM

#

What's the store argument?

primal heath Oct 17, 2023, 3:56 PM

#

WAIT

#

I DID IT

#

#

THE SCOPE COPYING DID NOT COPY VARIABLES

#

OMG

primal merlin Oct 17, 2023, 3:56 PM

#

yippee

primal heath Oct 17, 2023, 3:57 PM

#

HOLY

#

but I have so much memory leaks

#

lol

#

i had to use c_allocator instead of gpa

#

so my stdout didn't get bombarded

primal merlin Oct 17, 2023, 3:57 PM

#

did u consider freeing the memory when it was done being used

#

(i'm joking)
