minor code
cleanup found while searching for additional cases. Closes bug 171.

should have no impact on production performance and speed up debug
performance considerably, while making the code much cleaner. On some
benchmarks, debug builds now run _much_ faster.
We no longer have to sprinkle our code with things like:
if(debugTagIsOn("context")) {
Debug("context") << theContext << std::endl;
}
which we had to do to get around performance problems previously.
Now just writing:
Debug("context") << theContext << std::endl;
does the same in production and debug builds. That is, if "context"
debugging is off, theContext isn't converted to a string, nor is it
output to a "/dev/null" ostream. I've confirmed this. In production
builds, the whole statement inlines to nothing. I've confirmed this
too.
Also, "Debug" is no longer a #definition, so you can use it directly
in production builds where you couldn't previously, e.g.
if(Debug.isOn("paranoid:check_tableau")) {
checkTableau();
}
I'm leaving debugTagIsOn() for now, but marking it as deprecated.

post-rewrite, another full rewrite is performed and the results
compared).
Also added another response code to rewriters. Theories return a
CVC4::theory::RewriteResponse from preRewrite() and postRewrite().
This class has nice subclasses to make the theory rewriters somewhat
self-documenting in termination behavior. They look like
tail-recursive rewriting calls, but they're not; they are
instantiations of the RewriteResponse result code, which carries the
Node being returned:
// Flags the node as DONE pre- or post-rewriting, though this is
// ignored if n belongs to another theory.
//
// NOTE this just changed name from RewritingComplete(), which
// didn't match RewriteAgain().
//
return RewriteComplete(n);
// Flags the node as needing another pre-rewrite (if returned from a
// preRewrite()) or post-rewrite (if returned from a postRewrite()).
//
return RewriteAgain(n);
// Flags the node as needing another FULL rewrite. This is the same
// as RewriteAgain() if returned from preRewrite(). If it's returned
// from postRewrite(), however, this causes a full preRewrite() and
// postRewrite() of the Node and all its children (though the cache is
// still in effect, which might elide some rewriting calls).
//
// This would have been another fix for bug #168. Its use should be
// discouraged in practice, but there are places where it will
// probably be necessary, where a theory rewrites a Node into
// something in another theory about which it knows nothing.
// A common case is where the returned Node is expressed as a
// conjuction or disjunction of EQUALs, or a negation of EQUAL,
// where the EQUAL is across terms in another theory, and that EQUAL
// subterm should be seen by the owning theory.
//
return FullRewriteNeeded(n);

** file-level documentation at the top of the sources. **
This is the "make bugzilla stop bugging me" bugfix commit.
* Remove BackedNodeBuilder<> and collapse NodeBuilder<> hierarchy.
Updated documentation in the file. Resolves bug #99.
* Convenience NodeBuilders (PlusNodeBuilder, OrNodeBuilder, etc.)
moved into a separate file. Partially resolves bug #100.
* Moved isAssociative(Kind) into kind.h (and into the CVC4::kind
namespace) instead of metakind.h (where it was in CVC4::metakind).
This clears up a warning (private #inclusion) from the SMT and SMT2
parsers, and maybe makes more sense anyways, since this is based on
the kind (and not the metakind) of an operator.
* Documentation improvement; doxygen top-level \file gestures, \brief
gestures for files, etc. Changed contrib/update-copyright.pl for
this change, and post-processed to add \brief. Resolves bug #98.
* Removed ExprManager::mkExpr(Kind) and NodeManager::mkNode(Kind).
They no longer made sense. Resolves bug #91.

Adding function debugTagIsOn to safely test for tracing in any
compilation mode.
Removing irrelevant command-line options from usage message
in muzzled mode.

coverage for util and context classes; implemented some output functionality that was missing; reclassified some tests white -> black or black -> public; other minor fixes
|
|
* Other minor changes to the new parser to match coding guidelines,
add documentation, ....
* Add CFLAGS stuff to configure.ac parser Makefile.ams. This ensures
that profiling, coverage, optimization, debugging, and warning
level options will apply to the new parser as well (which is in C,
not C++). This fixes the deprecated warning we were seeing this
evening.
* Now, if you have ANTLR_HOME set in your environment, you don't need
to specify --with-antlr-dir to ./configure or have libantlr3c
installed in standard places. --with-antlr-dir still overrides
$ANTLR_HOME, and if the installation in $ANTLR_HOME is missing or
doesn't work, the standard places are still tried.
* Extend "silent make" to new parser stuff.
* Added src/parser/bounded_token_buffer.{h,cpp} to the list of
exclusions in contrib/update-copyright.pl and mention them as
excluded from CVC4 copyright in COPYING. They are antlr3-derived
works, covered under a BSD license.
OTHER STUFF:
* expr_manager.h, expr.h, expr_manager.cpp, and expr.cpp are now
auto-generated by a "mkexpr" script. This provides the correct
instantiations of mkConst() for public use, e.g., by the parser.
* Fix doxygen documentation in expr, expr_manager.. closes bug #35
* Node::isAtomic() implemented in a better way, based on theory kinds
files. Fixes bug #40. To support this, a "nonatomic_operator"
command has been added. All other "parameterized" or "operator"
kinds are atomic.
* Added expr_black test
* Remove kind::TRUE and kind::FALSE and make a new CONST_BOOLEAN kind
that takes a "bool" payload; for example, to make "true" you now do
nodeManager->mkConst(true).
* Make new "cvc4_public.h" and "cvc4parser_public.h" headers. Private
headers should include "cvc4_private.h"
(resp. "cvc4parser_private.h"), which existed previously. Public
headers should include the others. **No one** should include the
autoheader #include (which has been renamed "cvc4autoconfig.h")
directly, and public CVC4 headers can't access its #defines. This
is to avoid us having the same distribution problem as libantlr3c.
* Preliminary fixes based on Tim's code review of attributes (bug #61).
This includes splitting hairy template internals into
attribute_internals.h, for which another code review ticket will be
opened. Bug is still outstanding, but pending further
refactoring/documentation.
* Some *HashFcns renamed to *HashStrategy to match refactoring done
elsewhere (done by Chris?) earlier this week.
* Simplified creation of make rules for generated files (expr.cpp,
expr.h, expr_manager.cpp, expr_manager.h, theoryof_table.h, kind.h,
metakind.h).
* CVC4::Configuration interface and implementation split (so private
stuff doesn't leak into public headers).
* Some documentation/code formatting fixes.
* Add required versions of autotools to autogen.sh.
* src/expr/mkmetakind: fix a nonportable thing in invocation of "expr"
that was causing warnings on Red Hat.
* src/context/cdmap.h: add workaround to what appears to be a g++ 4.1
parsing bug.

test/unit/expr/node_white.h: add whitebox attribute test (pulled out
attribute stuff from node_white)
* test/unit/parser/parser_black.h: fix memory leaks uncovered by
valgrind
* src/theory/interrupted.h: actually make this "lightweight" (not
derived from CVC4::Exception), as promised in my last commit
* src/theory/uf/theory_uf.h, test/unit/expr/attribute_black.h: match
the new-style cleanup function definition
* src/expr/attribute.cpp, src/expr/attribute.h: support for attribute
deletion, custom cleanup functions, clearer cleanup function
definition.
* src/expr/node_manager.h, src/expr/node_manager.cpp: reclaim
remaining zombies in dtor, rename NodeValueSet ==> "NodeValuePool",
and enable freeing of NodeValues
* src/expr/type.h, src/expr/type.cpp: reference-counting for types,
customized cleanup function for types, also code cleanup
* (various): changed "const Type*" to "Type*" (to enable
reference-counting etc. Types are still immutable.)
* src/util/output.h: add ::isOn()-- which queries whether a
Debug/Trace flag is currently on or not.
* src/smt/smt_engine.cpp, src/parser/antlr_parser.cpp,
src/expr/type.cpp, src/expr/expr_manager.cpp, various others:
minor code cleanup
|
|
* CVC4::theory::Interrupted no longer derives CVC4::Exception.
* Interrupted is only thrown if "safe" parameter is TRUE !
* UF returns one conflict (instead of waiting for Interrupted to be thrown).
* Minor build system work (quieter builds if V=0, better handling of build
profiles in configure)
|
|
* configure.ac, test/unit/Makefile.am: Resolved an issue where even
when not testing, one unit test was built.
* Re-ran contrib/update-copyright.pl on all source files to ensure
consistent and correct header comments.
* contrib/get-authors: Change definition of "minor contributor"
to >= 10% of lines (rather than strictly greater than 10% of lines)
