clash-ghc-0.5.7: CHANGELOG.md

# Changelog for the [`clash-ghc`](http://hackage.haskell.org/package/clash-ghc) package

## 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*
