Sean Cross 8d128ba6d0 passes: opt_share: don't statically initialize mergeable_type_map 
In 3d3779b037 this got turned from a
`std::map<std::string, std::string>` to `std::map<IdString, IdString>`.
Consequently, this exposed some initialization sequencing issues (#1361).

Only initialize the map when it's first used, to avoid these static issues.

This fixes #1361.

Marcin Kościelnicki c6d5b97b98 review fixes 2019-08-13 00:35:54 +00:00
Marcin Kościelnicki f4c62f33ac Add clock buffer insertion pass, improve iopadmap. 
A few new attributes are defined for use in cell libraries:

- iopad_external_pin: marks PAD cell's external-facing pin.  Pad
  insertion will be skipped for ports that are already connected
  to such a pin.
- clkbuf_sink: marks an input pin as a clock pin, requesting clock
  buffer insertion.
- clkbuf_driver: marks an output pin as a clock buffer output pin.
  Clock buffer insertion will be skipped for nets that are already
  driven by such a pin.

All three are module attributes that should be set to a comma-separeted
list of pin names.

Clock buffer insertion itself works as follows:

1. All cell ports, starting from bottom up, can be marked as clock sinks
   (requesting clock buffer insertion) or as clock buffer outputs.
2. If a wire in a given module is driven by a cell port that is a clock
   buffer output, it is in turn also considered a clock buffer output.
3. If an input port in a non-top module is connected to a clock sink in a
   contained cell, it is also in turn considered a clock sink.
4. If a wire in a module is driven by a non-clock-buffer cell, and is
   also connected to a clock sink port in a contained cell, a clock
   buffer is inserted in this module.
5. For the top module, a clock buffer is also inserted on input ports
   connected to clock sinks, optionally with a special kind of input
   PAD (such as IBUFG for Xilinx).
6. Clock buffer insertion on a given wire is skipped if the clkbuf_inhibit
   attribute is set on it.

opt_lut to ignore LUT cells, or those that drive bits, with (* keep *)

whitequark 0b09a347dc proc_prune: fix handling of exactly identical assigns. 
Before this commit, in a process like:
   process $proc$bug.v:8$3
     assign $foo \bar
     switch \sel
       case 1'1
         assign $foo 1'1
         assign $foo 1'1
       case
         assign $foo 1'0
     end
   end
both of the "assign $foo 1'1" would incorrectly be removed.

Fixes #1243.
