Thanks for adding all of this. I am going to take a look now, and in the meantime wanted to leave these high level questions:
- Are we now able to measure a load/store correctly? I.e., is the measured value close to the SWOG number.
- This is quite a big patch, but most of the code here is boilerplate code to set up the environment. We are testing this only indirectly by running tests. Is there a way to dump the setup code so that we can look at it, and add a test that doesn't require running it?
- Similar question for the added test which requires running it, I guess for that one there is no way to statically check anything? We would get more testing if we don't require to run a test, which is why I am asking. The codegen of instruction and snippet is the same, it is just that the setup code is now fixed?
