Jakob Stoklund Olesen	a24daf5ded	Add a predicate_leafs() method. This collects all of the leaf predicates that go into a compound predicate. Current leaf predicates are: - Settings for ISA predicates, and - FieldPredicates for instruction predicates.	2016-08-25 09:50:23 -07:00
Jakob Stoklund Olesen	eb03abe864	Allow predicates on both EncRecipe and Encoding. If both specify a predicate, combine them with 'And'.	2016-08-24 16:02:41 -07:00
Jakob Stoklund Olesen	586fbbc797	Add RISC-V arithmetic w/immediate operand encodings. Add new instruction predicates to support the 'I' encoding recipe: IsSignedInt, IsUnsignedInt used to test that an immediate operand is in the allowed range.	2016-08-24 08:53:44 -07:00
Jakob Stoklund Olesen	9da6847805	Python 3 compat. Try to keep our Python sources compatible with both Python 2.7 and 3. Check with 'pylint --py3k' and 'python -3'.	2016-08-23 16:35:58 -07:00
Jakob Stoklund Olesen	c998c79fe8	Generate code to precompute predicates. Each ISA predicate is assigned a bit the the Flags struct, and a corresponding method is generated.	2016-08-12 10:13:50 -07:00
Jakob Stoklund Olesen	13d33d5a7a	Introduce predicates. Predcates are boolean functions. There will be ISA predicates and instruction predicates. The ISA predicates will be turned into member functions on the generated Flags structs.	2016-08-11 16:40:54 -07:00
