* Fix: Deeply nested assignments would offset the new columns count calculation. Now we track relevant columns and their path to ensure each row has wildcards if they don't contain the relevant column
* Add test plus clippy fix
* Clippy fix
* New version clippy fix
* Refactor and structuring optimizations to be less computationally heavy
* Forgot to commit the new file containing the optimization do over
* Point to correct functions in shrinker2
* Split out inline_constr_ops since it adds in builtins that can then be swept up by the builtin force reduction
* Fix: issue where identity reducer was always returning true
* Forward inlining on lambdas produces better results. This is due to a forward pass being able to apply an argument that may have no_inline at the top where as vice-versa would reduce the arg first.
* Clippy and test fixes
* Clear no_inlines when inlining a function
* Convert shrinker2 to replace shrinker and update tests
For recursive structures like Tuples, the span itself isn't enough to
ensure uniqueness of elements (in particular tuples) holding elements
of the same type.
This is only a start. It compiles, but with a few TODOs left open. In particular, it doesn't currently handle constants depending on other constants or functions; nor does it hoist constants.
Unfortunately, as documented in:
https://github.com/IntersectMBO/cardano-ledger/issues/4571
Some Option fields in the script context certificates are going to
remain set to None, at least until the next Hard fork. There's a risk
that people permanently lock their funds if they expect deposits on
registration credentials to ever be `Some`.
So, we introduce a special type that emulate an `Option` that can only
ever be `None`. We call it `Never` and it is the first type of this
kind (i.e. with constructors indexes not starting at 0).
Without that, we may encounter weird error messages when writing
validators without an explicit `else`. Since we automatically fill it
with a `fail`; without annotation, it unifies to a generic parameter.
The existing check that would look for the body being an error term is
ill-advised as it doesn't work as soon as one adds tracing, or make
the validator a parameterized validator. Plus, it may simply trigger
the wrong behavior as one can now annotate a validator with _whatever_
and get pass the type-checker by plucking a `fail` keyword as body.
- We now consistently desugar an expect in the last position as
`Void`. Regardless of the pattern. Desugaring to a boolean value is
deemed too confusing.
- This commit also removes the desugaring for let-binding. It's only
ever allowed for _expect_ which then behaves like a side effect.
- We also now allow tests to return either `Bool` or `Void`. A test
that returns `Void` is treated the same as a test returning `True`.
As well as fixing a couple of other issues thanks to conformance
tests. Some functions like multiply_integer or verify_ed25519_signature
have also slightly changed their costing function.
There were some odd discrepancy for `integerToByteString` on the mem
side. Either 1 or about 1000 mem units off; which I couldn't quite
figure out. Yet, it proves useful to validate builtin at large and
ensure we have a valid cost model for v3.
