core/vm: update gascosts for BLS12-381 + use gnark instead of kilic ( #29441 )
...
This PR updates the bls contracts from our internal implementation which is an unmaintained fork of the kilic library to the gnark-crypto library that is actively maintained by consensys.
It also updates the gas-costs according to the EIP

core/vm: add bn256ScalarMul testcase for zero scalar value ( #26607 )
...
EIP-196 allows a zero value in the scalar argument to precompile `0x07`. This change adds a test for that case.

core/vm: instruction tests ( #16327 )
...
This PR makes it easy to generate and execute testcases for VM arithmetic operations. By enabling and running the testcase TestWriteExpectedValues, a set of json files are created which contain input and output for each arith operation.
The test TestJsonTestcases executes all of those tests.
While meaningless as is, this PR makes it less risky to make changes (optimizations) to the vm operations, since there will be a larger body of testcases.
