4c6424c8a7 Fix for #662. 
This fix interprets integer division as "round down" division
in the symbolic simulator, to match the behavior of the concrete
simulator.

0ce797f0c9 Fix a bugged implementation of symbolic bit update for SBV words. 2020-03-23 14:49:17 -07:00
Rob Dockins
d26966101f Promote the logicShift out of the SBV module into a generic implementation. 
The concrete evaluator still uses a direct implementation, but this
one, based on a barrel-shifter, can also be used byt the what4 backend.

20ad7e8e86 Remove the "round-to-zero" versions of integer division and modulus, 
since we're going to restrict signed division to bitvectors.

72cf1ccd18 Implement the non-ring operations on Z_n via translation to integers 
directly in the `Backend` class definition.  Each backend was
essentially doing this anyway.

Also add an `integerAsLit` operation.

5af4469fe1 Reorganize sequence index and update operations. They now uniformly 
check for index in bounds conditions, and the interface between
the backend-specific operations is cleaned up.

9ed0c1d3a9 Make error handling uniform across the symbolic and concrete backends. 
Any non-concrete values in error messages are rendered as '?'
 2020-03-18 08:28:36 -07:00

bc99e7d791 Take bitLit out of the SEval monad. The backends all support 
a non-monadic version of bit literals, and it's somewhat more convenient.

47959c55cc Rearrange/reorganize the primitive tables for the SBV and Concrete 
backends to make them line up, and make it more obvious that most
of the primitives are uniformly defined for both backends.
The remaining primitives that have significant structural differences
are the sequence indexing and updating primitives, the shifts/rotates,
and `error`, `random` and `trace`.

While doing this, push the various to/from integer coercions
into the `Backend` class and make the operations uniform.

e079ab4cf6 Push the Logic, Cmp and SignedCmp class methods into the Backend 
and use generic implementations.

31109c2143 Push error handling into the backend class using methods 
that interact with the `SEval` monad.  Also, finish pushing
the methods of the `Arith` class into the evaluation backend
where they can be generically referenced by both the concrete
and symbolic evaluators.

9d74dd1383 In symbolic evaluation mode, use a monad that tracks safety conditions 
alongside the value being computed.  For now, this is just the infrastructure;
soon, we'll push the computation of side effects into the `Backend`
class, where they can interact with this new monad.

71b2f8ce70 Rename the BitWord class into Backend, and split into a separate 
module.  Push primitive type if/then/else operations into the `Backend`
class, and promote `iteValue` and `mergeValue` to operations
on generic values.

8718489531 Create a new sentinal datatype Concrete instead of using the unit 
type to indicate concrete evaluation.

be45b4ea29 Move definitions specific to the concrete evaluator in to separate 
modules.  The module structure needs to be a bit more cut up than
I would like to avoid module import cycles.

bdb8f49143 Refactor Cryptol.Symbolic.Prims and Cryptol.Symbolic.Value into 
a single new module `Crypol.Eval.SBV`.
 2020-03-09 14:32:07 -07:00
Rob Dockins
0341fd0480 Split out the primitive definitions used by multiple evalautors 
into a `Generic` module.  Refactor the `EvalPrims` class away,
pusing the `iteValue` operation into `BitWord` and demoting
the `evalPrim` operation into an ordinary (non-typeclass)
operation.
 2020-03-09 14:09:19 -07:00
Rob Dockins
fbbaed8c83 Rename module Cryptol.Prims.Eval into Cryptol.Eval.Concrete. 
This fits better into the current module structure, and is a lot
less confusing.

0bee8c4167 Remove the BitsVal constructor for WordVal and instead exclusively 
use the `LargeBitsVal` representation.  This simplifies a lot of code,
and is probably more efficent in the most cases anyway.

ce06a16d13 Push BitWord operations into IO and fixup 2020-03-05 16:28:56 -08:00
Rob Dockins
cb82015cd5 Refactor the BitWord class to use associated types, and fixup use sites. 
Uses of the `BitWord` operations now generally require an extra `sym`
argument that makes the types unambiguous, and this propigates through
quite a few functions.  This other `sym` argument will be necessary
when we make a `what4` backend, so it's a necessary refactor anyway.
