5.0.0 (2017-09-07)

• Support for LLVM 5.0

  We only give a summary of the changes affecting the public API of llvm-hs-pure here. Please refer to the official release notes for LLVM 5.0 for an overview of all changes in LLVM 5.0.

  • The X86_64_Win64 calling convention is now called Win64.
  • There is a new Speculatable function attribute.
  • The CrossThread synchronization scope has been removed. There is now a new System synchronization scope.

4.1.0 (2017-05-17)

• Switch AST to ByteString/ShortByteString reflecting LLVM’s use of C-style strings.
• preferredAlignment is now a Word32 instead of Maybe Word32. To recover the old behavior set it to the same value as abiAlignment.
• GlobalAlias now expects the element type of a pointer type instead of the pointer type itself. The address space is passed separately via the addrSpace field. This makes GlobalAlias consistent with GlobalVariable.
• The FloatingPointType constructor now takes a FloatingPointType argument instead of a width and a FloatingPointFormat to more closely match the LLVM IR language reference.
• The IsString instance of Name now throws an error on non-ASCII strings instead of silently discarding the upper bytes. There is also a new mkName function with the same behavior for easier discoverability. Non-ASCII names need to be encoded using an arbitrary encoding to to a ShortByteString which can then be used as a Name.
