⚠️ Breaking Changes Ahead ⚠️

• LLVMSwift now enforces deployment target constraints. In the future, we will continue to update this constraint in line with the LLVM homebrew package.
• The PassPipeliner is now provided as an alternative to FunctionPassManager, which may crash if used in many common situations. Please migrate accordingly.
• The FunctionPassManager is now deprecated
• Documentation for core components continues to improve
• An analog to LLVM’s infamous target Triple API has been added. APIs that previously dealt with Strings have been updated accordingly
• The bindings to ObjectFile were not correct and were not nearly feature-rich enough. The API has been completely overhauled
• The IRInstruction protocol has been added to unify instruction values around a common protocol.
• Metadata can now be attached to instructions
• The debug location accessor now supports being reset to nil without crashing
• DIFile now exposes file metadata, and file metadata now exposes its source text, directory, and name
• The Metadata Builder facility (MDBuilder) has been ported from LLVM
• Additional bit-manipulation primitives for setting and clearing bits and getting leading and trailing 1’s counts have been added to APInt
• The labels on FunctionType's initializer have been removed
• The internalize pass has been added
• All SROA passes no longer differentiate between their parameters. They are now deprecated - SROA is available under with the unified scalarReplacementOfAggregates pass
