Merge pull request #81 from mithro/libfixes 
Fix a number of issues with the generated liberty output
 2020-07-15 08:00:07 -07:00
Tim 'mithro' Ansell 296ef2066e scripts/liberty: Rework how attribute types are discovered. 
* Add functions for producing different types of values into liberty
   output (plus doctests for them).
 * Respect the type given by a `define()` statement.

If a library directory doesn't contain a 'cells' subdir, it's most
