Marcelina Kościelnicka 516857f3ba [NFCI] Deduplicate builtin FF cell types list 
A few passes included the same list of FF cell types.  Make it a global
const instead.

The zinit pass also seems to include a list like that, but given that
it seems to be completely broken at the time (see #1568 discussion),
I'm going to pretend I didn't see that.

Rupert Swarbrick 044ca9dde4 Add support for SystemVerilog-style `define to Verilog frontend 
This patch should support things like

  `define foo(a, b = 3, c)   a+b+c

  `foo(1, ,2)

which will evaluate to 1+3+2. It also spots mistakes like

  `foo(1)

(the 3rd argument doesn't have a default value, so a call site is
required to set it).

Most of the patch is a simple parser for the format in preproc.cc, but
I've also taken the opportunity to wrap up the "name -> definition"
map in a type, rather than use multiple std::map's.

Since this type needs to be visible to code that touches defines, I've
pulled it (and the frontend_verilog_preproc declaration) out into a
new file at frontends/verilog/preproc.h and included that where
necessary.

Finally, the patch adds a few tests in tests/various to check that we
are parsing everything correctly.

Merge pull request #1162 from whitequark/rtlil-case-attrs 
Allow attributes on individual switch cases in RTLIL
 2019-07-09 16:56:29 +02:00
Eddie Hung 41d7d9d24b Clarify script -scriptwire doc 2019-07-08 19:21:21 -07:00
whitequark 93bc5affd3 Allow attributes on individual switch cases in RTLIL. 
The parser changes are slightly awkward. Consider the following IL:

    process $0
      <point 1>
      switch \foo
        <point 2>
        case 1'1
          assign \bar \baz
          <point 3>
          ...
        case
      end
    end

Before this commit, attributes are valid in <point 1>, and <point 3>
iff it is immediately followed by a `switch`. (They are essentially
attached to the switch.) But, after this commit, and because switch
cases do not have an ending delimiter, <point 3> becomes ambiguous:
the attribute could attach to either the following `case`, or to
the following `switch`. This isn't expressible in LALR(1) and results
in a reduce/reduce conflict.

To address this, attributes inside processes are now valid anywhere
inside the process: in <point 1> and <point 3> a part of case body,
and in <point 2> as a separate rule. As a consequence, attributes
can now precede `assign`s, which is made illegal in the same way it
is illegal to attach attributes to `connect`.

Attributes are tracked separately from the parser state, so this
does not affect collection of attributes at all, other than allowing
them on `case`s. The grammar change serves purely to allow attributes
in more syntactic places.
