v0.64.0

A delayed update, contains some important bug fixes and improvements, notably:

1. raising errors on when setting operation fields (operands, results, attributes, properties, regions, successors), as these were broken since migrating to Python's (tnaks @ed741!).
2. backend dialect operations now correctly declare memory effects both for main memory and registers when in allocated form
3. Many more llvm op conversions and bug fixes (thanks @sueszli!)
4. Introducing .get class method on constraints for optimisation on construction (thanks @alexarice!)

v0.59.0

This is a release with one change, which is fairly mechanical but required a bit of work to update the tests for. With this change, block arguments (which includes function arguments) don't insert a space after the SSAValue name and the :.

Before:

func.func @foo(%arg0 : i32, %arg1 : i64) {

After:

func.func @foo(%arg0: i32, %arg1: i64) {

Changes

xDSL framework

• core: don't insert space between block arguments and colons @superlopuh (#5745)

v0.58.0

Targets can now be added to Universes, meaning that xdsl-opt -t can be used to emit text by projects in the same Python environment.

Changes

xDSL framework

• core: add targets to multiverse @superlopuh (#5736)
• core: (Constraints) allow of_length to take an int @alexarice (#5734)
