crates/blockifier/src/blockifier_versioned_constants.rs line 950 at r2 (raw file):
impl BuiltinGasCosts { pub fn get_builtin_gas_cost(&self, builtin: &BuiltinName) -> Result<u64, GasCostsError> {
This will be made private, and outer use will only be by fn get_cairo_primitive_gas_cost
(I added TODO in the following PR #12462)

Note
Low Risk
Small, additive API surface in gas-cost lookup logic with no changes to pricing values or transaction execution flow.
Overview
Adds support for querying gas costs by Cairo primitive name (builtin or opcode) in
BuiltinGasCosts.This introduces
get_opcode_gas_cost(currently mappingOpcodeName::Blake) and a unifiedget_cairo_primitive_gas_costthat dispatches to either builtin pricing (with existing error handling) or opcode pricing.Written by Cursor Bugbot for commit 8469e09. This will update automatically on new commits. Configure here.
