feat: add as_witness
builtin function in order to constrain a witness to be equal to a variable
#4641
Conversation
I've confirmed that this works on @zac-williamson's poseidon circuit. Happy to bikeshed on naming. |
I'd like to hold off on this unless @zac-williamson really needs a fix today for this. I just don't see regular users being able to debug to the point where they can identify the exact point to add |
Happy to hold off on this if it's not urgent, just good to have this in our back pocket. |
@jfecher can you approve? |

Description
Problem*
Quick fix to #4629
Summary*
This PR adds a
as_witness
function which takes aField
and instructs the compiler to lay down an opcode which constrains a witness to be equal to this value.This prevents the issue in #4629 where we collect ever growing expressions which need to be broken down multiple times while reshaping the circuit. Doing this during acirgen instead allows us to avoid this repetition.
