--- Comment #4 from Jacob Lifshay <programmerjake at gmail.com> ---
I added all the pseudo-code and fields.txt stuff, will add unit tests next.

while doing that, I got fed up with the terrible pseudo-code syntax error
reports and fixed that to use Python's normal location reporting, which has the
added benefit that IDEs understand that error format and can go straight to the
syntax error in the file.
errors now look like:
  File
"/home/jacob/projects/libreriscv/openpower-isa/src/openpower/decoder/pseudo/parser.py",
line 873, in p_error
    self.input_text)
  File
"/home/jacob/projects/libreriscv/openpower-isa/src/openpower/decoder/pseudo/lexer.py",
line 21, in raise_syntax_error
    input_text[line_start:line_end]))
  File
