Erik Eckstein	3f95ce9645	Optimizer: fix spelling of the Simplifiable protocol ... Rename `Simplifyable` -> `Simplifiable` NFC	2025-02-12 09:01:11 +01:00
Erik Eckstein	cd7c533d42	Optimizer: add SingleValueInstruction.replace(with:) and use it throughout the optimizer ... It replaces all uses and then erases the instruction.	2024-12-19 20:53:45 +01:00
Erik Eckstein	e14c1d1f62	SIL, Optimizer: update and handle borrowed-from instructions ... Compute, update and handle borrowed-from instruction in various utilities and passes. Also, used borrowed-from to simplify `gatherBorrowIntroducers` and `gatherEnclosingValues`. Replace those utilities by `Value.getBorrowIntroducers` and `Value.getEnclosingValues`, which return a lazily computed Sequence of borrowed/enclosing values.	2024-04-10 13:38:10 +02:00
Erik Eckstein	d9826f6043	SimplifyBranch: don't leave an empty block after merging two basic blocks ... Although empty blocks are cleaned up at the end of every Simplification pass, it's not legal SIL to have empty blocks and subsequent simplification passes may crash because of this. rdar://115169880	2023-09-11 14:11:46 +02:00
Erik Eckstein	3f35a1d869	Swift Optimizer: add Onone simplification of branch instructions	2023-02-09 06:50:05 +01:00
