llvm-hs-pure is a set of pure Haskell types and functions for interacting with LLVM http://llvm.org/.
It includes an ADT to represent LLVM IR (http://llvm.org/docs/LangRef.html). The llvm-hs package
builds on this one with FFI bindings to LLVM, but llvm-hs-pure does not require LLVM to be available.
Changes
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 NoTailTailCallKind
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)
