llvm-hs-pure

9.0.0 (2019-09-06)

• The functions in LLVM.IRBuilder.Constant no longer return a monadic context. To recover the previous behavior use pure. (Thanks to @jfaure)
• LLVM.IRBuilder.Instruction.globalStringPtr returns a Constant instead of an Operand. (Thanks to @jfaure)
• Fresh name generation in the IRBuilder should be significantly faster (Thanks to @luc-tielen)
• Update to LLVM 9.0
  • The MainSubprogram constructor from DIFlag has been removed and a few new flags have been added.

8.0.0 (2019-03-10)

• Upgrade to LLVM 8
• Change type of value field in DITemplateValueParameter to Maybe Metadata to reflect that it can be null.

7.0.0 (2018-09-28)

• Track type definitions in MonadModuleBuilder. This allows us to automatically resolve NamedTypeReferences in gep instructions. Note that type definitions must be defined before they are used (i.e. MonadFix will not behave correctly here).
• Change the type of gep in the IRBuilder API to require a MonadModuleBuilder constraint.
• Change the type of typedef in the IRBuilder API to return a NamedTypeReference to the newly defined type.
• Update for LLVM 7.0:
  • Add isUnsigned field to DIEnumerator.
  • Change DISubrange to use the new DICount type instead of an Int64.
  • Merge checksum and checksumKind fields of DIFile into a checksum field of type Maybe ChecksumInfo.
  • Rename the variables field of DISubprogram to retainedNodes.

6.2.1 (2018-06-12)

• Fix type of shuffleVector in the IRBuilder API.

6.2.0 (2018-05-08)

• Remove field prefixes from DIDerivedType, DIBasicType and DISubroutineType to make the API consistent with the other debug metadata types.
• Change the type of the scope fields in DIModule and DINamespace to Maybe (MDRef DIScope) to reflect that they can be optional.

6.1.0 (2018-05-05)

• IRBuilder: Ensure that automatically generated block labels are assigned smaller identifiers than the instructions following them. This is only important when you use llvm-hs-pretty. llvm-hs does not care about the order of identifiers assigned to unnamed values.
• IRBuilder: add currentBlock which returns name of the currently active block.
• Remove the MetadataNodeReference constructor. References to metadata nodes are now encoded using the polymorphic MDRef type.
• Add debug metadata to the AST in LLVM.AST.Operand. Thanks to @xldenis who started that effort!
• Drop support for GHC 7.10.
• Add metadata field to GlobalVariable and Function.

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.
