description:
SCons: Make the ISA parser a source for its output files like the
comments say.
There was a change a while ago that refactored some scons stuff which
got rid
of cpu_models.py but also accidentally got rid of the ISA parser as a
source
for its target files. That meant that changes which affected the parser
wouldn't cause a rebuild unless they also changed one of the description
files. This change fixes that.
