Erik Eckstein	cc68bd98c9	Swift Optimizer: rework pass context types and instruction passes ... * split the `PassContext` into multiple protocols and structs: `Context`, `MutatingContext`, `FunctionPassContext` and `SimplifyContext` * change how instruction passes work: implement the `simplify` function in conformance to `SILCombineSimplifyable` * add a mechanism to add a callback for inserted instructions	2023-01-16 15:11:34 +01:00
Erik Eckstein	6c35258f83	Swift SIL: rename parent accessors to parentX, e.g. Instruction.parentBlock ... It makes it easier to read	2023-01-16 15:11:34 +01:00
Erik Eckstein	d4d1620f28	Swift SIL: rework Instruction and BasicBlock lists to support deleting instructions during iteration ... Replace the generic `List` with the (non-generic) `InstructionList` and `BasicBlockList`. The `InstructionList` is now a bit different than the `BasicBlockList` because it supports that instructions are deleted while iterating over the list. Also add a test pass which tests instruction modification while iteration.	2022-12-12 19:08:57 +01:00
