1e42aac41a [meta] Add new instruction predicates and the InstructionPredicateMap; 
The latter helps deduplicating predicates during encodings and recipes
construction.

ec5678ab7a [meta] Add the ability to bind any type to an instruction; 2019-07-03 18:39:28 +02:00

18fb87cd9c [meta] Refactor instruction predicates to distinguish format and type checks; 
Also add the instruction format name in format predicates, since they're
going to be used when generating encodings.

d9277f249b [meta] Introduce the InstructionGroupBuilder; 
This follows the rest of the code base data structures, where we have a
mutable data structure builder; once the data structure is constructed,
it's immutable.

This also makes the definition of instructions easier, and it paves the
way for defining immediate variants.

390cfb37da [meta] Use named predicates for x86 settings in the Rust crate too; 
And generate them using the same deterministic order that the Python
code uses.

dfb27c3402 [meta] Make TypeVar shareable and mutable; 
... since its type set can change over time during type inference. Use a
Rc<RefCell> to achieve this.

d92778a19e [meta] Add Instruction helpers and change its representation to make it easily copiable; 
- adds helpers used by other parts of the code
- allows cheap copies by having Instruction be a lightweight ref-cloned
wrapper of the actual instruction's content.

2dd1552369 [meta] Make Typevar::type_set private, and add a second getter to read it directly; 
There might be a silent bug in the Python module which directly reads
from this type_set field; in particular, it does so when reading all
controlling type variables, which all seem to be free variables (i.e. no
parent typevar). So imitate this behavior here, until we're sure there
are no other meta generators that rely on this.

5edee84f67 [meta] Port TypeVar's test_functions to Rust; 
Fixes two issues:

- name of derived type variables wasn't correct. (This is used during
code generation.)
- the TypeVar::derived() function wasn't creating the correct type set
(and would instead propagate the parent's one).
