Architecture names follow L4V_ARCH-style naming conventions ('ARM', 'FAKE64').
However, the standalone parser does not make use of the L4V_ARCH environment
variable.
The standalone-parser Makefile builds all architectures at once, producing
binaries at 'ARM/c-parser', 'FAKE64/c-parser', and similarly for the tokenizer.
There are also wrapper scripts 'c-parser' and 'tokenizer' in the
standalone-parser directory, which take an architecture on the command line.
The make_munge.sh script calls the appropriate binary parser directly.
The idea of this file is to allow users to determine how the simpset,
cong set, intro set, wp sets, etc. have changed from an old version of
the repository to a new version.
The process is as follows:
1. A user runs "save_attributes" on an old, working version of the
theory.
2. This tool will write out a ".foo.attrib_trace" file for each
theory processed.
3. The user modifies imports statements as required, possibly
breaking the proof.
4. The user can now run "diff_attributes" to determine what
commands they should run to restore the simpset / congset /etc
to something closer to the old version.
The tool is not complete, in that it won't always suggest the full set
of "simp add", "simp del", etc commands. Nor does it know that a rule
added to the simpset is causing a problem. It merely lists
a hopefully-sensible set of differences.
