6.0.0 (2018-03-06)

• Support for LLVM 6.0
  • Add StrictFP and SanitizeHWAddress function attributes.
  • Remove UnsafeAlgebra constructor from FastMathFlags.
  • Add allowReassoc, allowContract and approxFunc fields to FastMathFlags.
  • Remove NoFastMathFlags constructor since it is equivalent to setting all fields in the FastMathFlags record to False. Existing uses of NoFastMathFlags can be replaced by the noFastMathFlags value.
• Add AggregateZero for zero-initializing structs, arrays and vectors. Previously Null was used for null pointers as well as zero-inializing aggregates. The new behavior reflects LLVM’s internal representation and the C++-API. Existing uses of Null on non-pointer types must be changed to AggregateZero.
• Fix recursive function calls in the IRBuilder API.

5.1.2 (2018-01-06)

• Fixes and enhancements to the IRBuilder
  • sdiv and udiv no longer default to exact.
  • Fix type of global references.
  • Add more instructions.

5.1.1 (2017-12-16)

• Add a completely new API for building modules in a monadic style similar to the IRBuilder provided by LLVM’s C++ API. The modules can be found in LLVM.IRBuilder. An example can be found in the readme and in the test suite.
• Add an API for getting the type of LLVM values in LLVM.AST.Typed. This is primarily intended to be used in other libraries that build upon llvm-hs-pure such as llvm-hs-pretty.

5.1.0 (2017-10-12)

Enhancements

• Suport string attributes as parameter attributes
• Support more calling conventions
• Support NoTail TailCallKind

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.

4.0.0 (initial release, changes in comparison to llvm-general)

• Move modules from LLVM.General* to LLVM.*
• Support for LLVM 4.0
• Improved support for LLVM’s exception handling instructions
• -fshared-llvm is now supported on windows (thanks to @RyanGLScott)
• Default to -fshared-llvm
• Expose LLVM.Internal.* modules.
