Erik Eckstein	3f95ce9645	Optimizer: fix spelling of the Simplifiable protocol ... Rename `Simplifyable` -> `Simplifiable` NFC	2025-02-12 09:01:11 +01:00
Erik Eckstein	318c30895f	Swift Optimizer: eliminate ARC operations on types which are marked as immortal ... A type (mostly classes) can be attributed with `@_semantics("arc.immortal")`. ARC operations on values of such types are eliminated. This is useful for the bridged SIL objects in the swift compiler sources.	2023-03-14 21:07:03 +01:00
Erik Eckstein	f1095556c9	Swift SIL: let var UnaryInstruction.operand return an Operand and not a Value ... To avoid confusion. Instead add specific getters for unary instructions with dedicated names. NFC	2023-02-21 17:57:29 +01:00
Erik Eckstein	85210a4e91	Swift Optimizer: make some SILCombine optimizations available for the "Simplification" pass ... * begin_cow_mutation * global_value * strong_retain and strong_release So far, those simplifications did only run in SILCombine. Now they are also considered in the swift Simplification pass.	2023-02-09 06:50:05 +01:00
Erik Eckstein	ea746479ad	SIL Optimizer: rename directory InstructionPasses -> InstructionSimplification	2023-01-16 16:16:51 +01:00
