Changelog for the clash-lib package

0.5.13 September 21st 2015

• Fixes bugs:
  • Performance bug: top-level definitions of type “Signal” erroneously inlined.

0.5.12 September 14th 2015

• New features:

  • Completely unroll “definitions” of some higher-order primitives with non-representable argument or result vectors: It is now possible to translate e.g. f xs ys = zipWith ($) (map (+) xs) ys :: Vec 4 Int -> Vec 4 Int -> Vec 4 Int

• Fixes bugs:

  • topLet transformation erroneously not performed in a top-down traversal
  • Specialisation limit unchecked on types and constants
  • Vector of functions cannot be translated #25
  • CLaSH fails to generate VHDL when map is applied #78

0.5.11 September 7th 2015

• Fixes bugs:
  • Clash running out of memory on Simple-ish project #70
  • CLaSH.Sized.Vector.:> was not allowed as a function argument to HO-primitives

0.5.10 August 2nd 2015

• Fixes bugs:
  • Make testbench generation deterministic
  • Compile against unbound-generics-0.2

0.5.9 July 9th 2015

• Fixes bugs:
  • coreView didn’t look through newtypes of the form: newtype Foo a = MkFoo (Maybe a)

0.5.8 June 26th 2015

• Fixes bugs:
  • Allow text and tags in ~SIGD black box construct

0.5.7 June 25th 2015

• New features:

  • Support for copying string literals from Haskell to generated code
  • Collect and copy data-files

• Fixes bugs:

  • Signals declared twice when not using a clock-generating component #60
  • This piece of code eat up all CPU when generating verilog #62

0.5.6 June 3rd 2015

• New features:
  • Support Verilog backend
  • Generated component names are prefixed by the name of the module containing the topEntity

0.5.5 May 18th 2015

• New features:

  • Make inlining and specialisation limit configurable
  • Make debug message level configurable

• Fixes bugs:

  • Netlist: ensure that the arguments of a component instantiation are always simple variables
  • CaseCon transformation: ensure that we run the compile-time evaluator on the subject before handling the one-alternative case
  • Emit a warning if a function remains recursive, instead of producing an error: compilation can still be successful if the function is an argument to a higher-order blackbox that doesn’t use the function.
  • Emit a warning if inlining limit is reached, instead of producing an error: compilation can still be successful if the function is an argument to a higher-order blackbox that doesn’t use the function.
  • Always inline terms that have a type of kind Constraint

0.5.4 May 10th 2015

• New features:
  • Add ~COMPNAME tag: primitives get access to the component name in which they are instantiated

0.5.3 May 5th 2015

• New features:
  • TopEntity wrappers are now specified as ANN annotation pragmas
• Fixes bugs:
  • Lost system1000 clock in VHDL generation… #53
  • flattenCallTree sometimes introduces free variables

0.5.2 May 1st 2015

• New features:
  • Generate wrappers around topEntity that have constant names and types

0.5.1 April 20th 2015

• GHC 7.10 support

0.5 March 11th 2015

• New features:

  • Simplify BlackBox handling, and improve VHDL generation. #47
  • Use unbound-generics. #48

• Fixes bugs:

  • VHDL generation error: wrapper for sum-of-products type. #44

0.4.1 February 4th 2015

• Fixes bugs:
  • Treat BlackBox expressions as declarations when DC args. #37
  • Don’t inline recursive closed bindings

0.4 November 17th 2014

• New features:

  • Support for clash-prelude 0.6
