This includes a tweak to Word_Lib to simplify ucast(-1) which
is now a term that occurs more often.

Some code in the parser would incorrectly delete the source file
jiraver337.c, because the `Path` module now normalises the filename to
a different-looking name. This is fixed by adding a boolean flag for
whether the parsed file should be deleted or not.
Fixes Jira VER-1114.
Unify some tracing features that didn't go through the Feedback structure.
Add config to isar_install allowing Feedback to be traced to a file in real
time as well as to standard Isabelle output channels.
The C-parser contains a full parser for __asm__ syntax but
up until now hasn't done anything with it. Instead we export
some semantics. It's unspecified exactly what these semantics
are but they are parametrised with the __asm__ semantics that
went in to them, so the translation validation has something
to reason about.
Tweak modifies proofs as a result, and add some more test files.
Depends on configuration variable (as per example in
testfiles/jira473.thy), "munge_info_fname". If this is not set, then no
export occurs. File written is with respect to directory Isabelle is
started in, which may not be ideal.
Format in the file is a series of lines:
function_name::var_name -> munged_name
If the variable is global, then function_name is blank.

Japheth's recent change (6f7c660cb) to error-reporting for the latter
broke the former. Refactor code so that old and new code can coexist.
Would just use Japheth's code in the purely SML version too, but it uses
Isabelle/ML libraries that I can't be bothered to recreate in SML.
The handling of local static variables is now part of a general
improvement in the handling of all the "munging" that the parser does.
*Munging* is the process of renaming variables so that Isabelle can cope
with them. There are at least three different forms of munging at the
moment:
- static locals get munged so that multiple static locals (which have to
be treated as globals) can co-exist with the same source name.
- local variables of the same source name but different types have to be
able to co-exist
- variables with legitimate C names but illegal Isabelle names have to
be allowed
The new structure MString implements an opaque version of string
designed to make it clear to the typechecker that certain strings are
"munged".
In particular, don't reveal the internal references used during
yacc-ing to the user-level. Instead, add a referentially transparent
repair of the AST after its been parsed.
JIRA VER-432
As per example, syntax is
declare [[cpp_path="path to file"]]
If the empty string is used as the value, then no preprocessor will be
called.
The standalone parser has also been adjusted so that you can it with
--cpp=path
or
--nocpp
options.
Closes JIRA issue VER-337
The functor is gone, and instead StaticFun exports two more general
operators, one for defining a partial map by a tree, and one for
extracting the theorems from an existing partial map definition.
The extraction process uses simplification in a more conservative
manner than before, and is guaranteed to produce exactly the
expected theorems.
CParser not finished yet, though: getting errors in cparser_test about linear
theory updates at end of thy.
Found more instances where we should be using Local_Theory.exit_global, but
might be besides the point (didn't help). Also might be overshooting the goal.
