sail2_instr_kinds was in the folder with the old lem interpreter for
some reason, rather than with all the other sail2*.lem files

This reverts commit 3fb4cf236c0d4b15831576faa45c763853632568.

Unlike the prompt-monad change I don't see a way to do this easily
purely on the model side
Make sure a64_barrier_type and domain aren't visible for RISC-V

One day we will be free from the 4.02.3 menace, but today is not that day. :(
This should fix Sail on Jenkins
This reverts commit 86e29bcbb1597c4ef1f6cae8edbeed42f9a31414.

Changes are:
- String.capitalize -> String.capitalize_ascii
- String.uppercase -> String.uppercase_ascii
- String.lowercase -> String.lowercase_ascii
Basically just making the change that the warning message suggested.

- Use simplified monad type (e.g., without the with_aux constructors that are
not needed by the shallow embedding).
- Add support for registers with arbitrary types (e.g., records, enumerations,
vectors of vectors). Instead of using bit lists as the common representation
of register values at the monad interface, use a register_value type that is
generated per spec as a union of all register types that occur in the spec.
Conversion functions between register_value and concrete types are generated.
- Use the same representation of register references as the state monad, in
preparation of rebasing the state monad onto the prompt monad.
- Split out those types from sail_impl_base.lem that are used by the shallow
embedding into a new module sail_instr_kinds.lem, and import that. Removing
the dependency on Sail_impl_base from the shallow embedding avoids name clashes
between the different monad types.
Not yet done:
- Support for reading/writing register slices. Currently, a rewriting pass
pushes register slices in l-expressions to the right-hand side, turning a
write to a register slice into a read-modify-write. For interfacing with the
concurreny model, we will want to be more precise than that (in particular
since some specs represent register files as big single registers containing a
vector of bitvectors).
- Lemmas about the conversion functions to/from register_value should be
generated automatically.

removed IK_cond_branch, and added IK_branch
|
|
|
|
- Remove vector start indices
- Library refactoring: Definitions in sail_operators.lem now use Bitvector
type class and work for both bit list and machine word representations
- Add Lem bindings to AArch64 and RISC-V preludes
TODO: Merge specialised machine word operations from sail_operators_mwords into
sail_operators.

The type-checker already supports a user-defined "exception" type that can be
used in throw and try-catch expressions. This patch adds support for that to
the Lem shallow embedding by adapting the existing exception mechanisms of the
state and prompt monads. User-defined exceptions are distinguished from
builtin exception cases. For example, the state monad uses
type ex 'e =
| Exit
| Assert of string
| Throw of 'e
to distinguish between calls to "exit", failed assertions, and user-defined
exceptions, respectively. Early return is also handled using the exception
mechanism, by lifting to a monad with "either 'r exception" as the exception
type, where 'r is the expected return type and "exception" is the user-defined
exception type.

Also fix bug in mono analysis with generated variables
Breaks lots of typechecking tests because it generates unnecessary
equality tests on units (and the tests don't have generic equality),
which I'll fix next.
|

|
|
- Add support for some internal nodes to type checker
- Add more explicit type annotations during rewriting
- Remove hardcoded rewrites for E_vector_update etc from Lem pretty-printer;
these will be resolved by the type checker during rewriting now

Instruction extractor code that I commented out in this commit seems
buggy anyway - it will claim that the length of all bitvectors is 64?!
|
|
Need to map sail type annotations to interpreter type annotations in lem_ast ouput. This doesn't seem too hard.

registers is no longer xored with 48 so need to initialise it. Also use E and T values used by CHERI hw and adjust decoding functions appropriately. Fix shift functions for ocaml shallow embedding which failed to handle shifts greater than vector length.
