Deployment tests: trivial deployments

[OlivierBBB]

Definitions

Trivial CREATE's are those CREATE's that are

• unexceptional
• don't abort
• don't raise the failure condition F
• but deploy with empty initialization code

Parameters

In terms of the parameters we can play with we find:

• level
  • root level
  • higher level
• CREATE vs CREATE2
• zero value vs nonzero value
• WILL_REVERT vs WONT_REVERT
• zero size
  • 'zero size, huge offset' shenanigans
• nonzero size

We could also consider collisions via CREATE2 or through multi transactions and SELFDESTRUCT's.
This will be the focus of other tests. We should also measure the interaction that these trivial deployments have with EXTCODEHASH.
Furthermore, we should see how these deployments squash any return data (if present.) And then there is obviously the question of deployment numbers, deployment statuses.

• EXTCODEHASH before and after
• squashing of return data and RETURNDATASIZE
• warmth post deployment (EXTCODEXXX + BALANCE + CALL's + SELFDESTRUCT heir + ...)
