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	aea26bbc6e	Swift SIL: add a utility protocol NoReflectionChildren for better debug output with lldb po ... Let's lldb's `po` command not print any "internal" properties of the conforming type. This is useful if the `description` already contains all the information of a type instance.	2022-10-05 07:37:41 +02:00
Erik Eckstein	de6e539a0a	Swift Optimizer: make the set's insert functions return a Bool. ... Returning true if the element was not contained in the set before inserting	2022-08-24 17:54:46 +02:00
Erik Eckstein	4824d6d940	Swift SIL: improve BasicBlockRange and InstructionRange and add tests ... * add `BasicBlockRange.inclusiveRange` * add `insert(contentsOf:)` * add the RangeDumper pass to dump ranges for testing * and add a test file	2022-03-30 14:45:58 +02:00
Erik Eckstein	40200d6544	Swift Optimizer: add BasicBlock utility data structures and rename StackList ... * add `BasicBlockSet` * add `BasicBlockWorklist` * add `BasicBlockRange`, which defines a range of blocks from a common dominating “begin” block to a set of “end” blocks. * add `InstructionRange`, which is similar to `BasicBlockRange`, just on instruction level. It can be used for value lifetime analysis. * rename `StackList` -> `Stack` and move it to `Optimizer/DataStructures` * rename `PassContext.passContext` to `PassContext._bridged` * add notify-functions to PassContext	2022-01-12 15:47:16 +01:00
