Changelog of @hackage/clash-ghc 0.5.13

Changelog for the clash-ghc package

0.5.13 September 8th 2015

  • Fixes bugs:
    • Cannot translate GHC MachLabel literal
    • Maybe (Index n) not translatable to VHDL #75

0.5.12 September 7th 2015

  • New features:

    • Modest compilation time speed-up. Compilation time of the I2C module on my machine went down from 43s to 24s, and maximum memory usage went down from 840 MB to 700 MB.

  • Fixes bugs:

    • Bug in VHDL ROM generation #69
    • Clash running out of memory on Simple-ish project #70
    • Fix asyncRom VHDL primitive #71
    • Fix primitive for CLaSH.Sized.Internal.Signed.size# #72
    • rem and quot on Signed are broken #73

0.5.11 August 2nd 2015

  • New features:
    • Re-enable GHC's strictness analysis pass, which improves dead-code removal, which hopefully leads to smaller circuits.

0.5.10 July 9th 2015

  • New features:
    • Use new VHDL backend which outputs VHDL-93 instead of VHDL-2002: generated VHDL is now accepted by a larger number of tools.
    • Treat all so-called bottom values (error "FOO", let x = x in x, etc.) occuring in installed libraries as undefined. Before, there were (very) rare situations where we couldn't find the expressions belonging to a function and demanded a BlackBox, even though we knew the expression would be a bottom value. Now, we stop demanding a BlackBox for such a function and simply treat it as undefined, thus allowing a greater range of circuit descriptions that we can compile.

0.5.9 June 26th 2015

  • New features:

    • Use new verilog backend which outputs Verilog-2001 instead of Verilog-2005: generated Verilog is now accepted by Altera/Quartus

  • Fixes bugs:

    • --systemverilog switch incorrectly generates verilog code instead of systemverilog code

0.5.8 June 25th 2015

  • New features:
    • Support for copying string literals from Haskell to generated code
    • Support clash-prelude-0.9
    • Size at below which functions are always inlined is configurable, run with -clash-inline-below=N to set the size limit to N

0.5.7 June 3rd 2015

  • New features:
    • New Verilog backend, run :verilog in interactive mode, or --verilog for batch mode
    • Generated component names are prefixed by the name of the module containing the topEntity

0.5.6 May 18th 2015

  • New features:

    • Inlining limit is configurable, run with -clash-inline-limit=N to set the inlining limit to N
    • Specialisation limit is configurable, run with clash-spec-limit=N to set the inline limit to N
    • Debug level is configurable, run with -clash-debug <LEVEL> where <LEVEL> can be: DebugNone, DebugFinal, DebugName, DebugApplied, DebugAll. Be default, clash runs with DebugNone.

  • Fixes bugs:

    • Extend evaluator for GHC.Integer.Type.minusInteger and CLaSH.Promoted.Nat.SNat.

0.5.5 May 5th 2015

  • New features:
    • TopEntity wrappers are now specified as ANN annotation pragmas #42

0.5.4 May 1st 2015

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

0.5.3 April 24th 2015

  • Fixes bugs:
    • Fix bug where not enough array type definitions were created by the VHDL backend

0.5.2 April 21st 2015

  • Use latest ghc-typelits-natnormalise

0.5.1 April 20th 2015

0.5 March 11th 2015

  • New features:
    • SystemVerilog backend. #45
