changelog

c++经典教材 Blitz++ v0.8

	defined shape in the expression is INT_MIN, not INT_MAX.
	* blitz/vecuops.cc: Freshly generated vecuops.cc header with new
	support for conj() function.
	* blitz/generate/genvecuops.cpp: Added support for complex math
	operations and added conj() to list of generated unary operations
	for vector types.
	* blitz/vecexpr.h: Added missing unary minus operator for
	VectorPick and TinyVector types.

2003-07-22  Julian Cummings  <[e-mail]>

	* blitz/array/methods.cc: Patch from Derrick Bass to correct a bug
	that could lead to incorrect Array ordering data when performing
	reductions.

2003-06-25  Julian Cummings  <[e-mail]>

	* blitz/array/fastiter.h: FastArrayIterator now uses
	ConstPointerStack helper class.
	* blitz/array/iter.h: Added helper class ConstPointerStack that
	manages an array of saved const data pointers used in array
	iterators.  Moving the array of saved pointers into a separate
	class eliminates compiler warnings about potentially unsafe
	assignments between restricted and unrestricted pointers in the
	same scope.  ArrayIterator and ConstArrayIterator now have
	ConstPointerStack data members.
	* blitz/memblock.cc: Allocate memory block using unrestricted
	pointer dataBlocxkAddress_ and then assign to restricted pointer
	data_ to eliminate compiler warnings about assignments between
	restricted pointers.
	* blitz/memblock.h: Removed restrict label from dataBlockAddress_
	pointer, since only the data_ pointer is used in expression
	evaluation and needs to be restricted.
	* configure.in: Added -qhot to list of C++ optimization flags for
	IBM xlC compiler, since it now supports higher-order transforms as
	of version 6.0.

2003-06-16  Patrick Guio <[e-mail]>
	* configure.in: Fixed 2 flags setting for CC/SGI. 

2003-05-16  Julian Cummings  <[e-mail]>

	* blitz/array/map.h: Fixed error in ascending() method reported by
	Derrick Bass.  The name of the corresponding method in the Array
	class is isRankStoredAscending().  This method returns a bool, but
	it is treated here as an int for the purposes of doing a reduction
	across operands.

2003-05-16 Patrick Guio <[e-mail]>
        * configure.in: Fixed several bugs for CC/SGI setup. Library Cio should be
	included as well as -ptused.

2003-05-09 Patrick Guio <[e-mail]>
	* doc/stencils/Makefile.am: Fixed lib path to be used with libtool stuff

2003-04-02 Patrick Guio <[e-mail]>
	* blitz/array/resize.cc: Added the definition of the Array class member 
	function resize(...) with Range argument as it was declared already
	present in the Array class declaration.

2003-03-31 Patrick Guio <[e-mail]>
	* lib/Makefile.am: Enable required libtool library target libblitz.la since
	AC_PROG_LIBTOOL is now in use.

2003-03-28 Theodore Papadopoulo <[e-mail]>

    * configure.in: Re-enable AC_PROG_LIBTOOL and disable AC_PROG_RANLIB
    since now libtool is used.

2003-03-28 Theodore Papadopoulo <[e-mail]>

    * doc/examples/Makefile.am: Added $(top_builddir) in include path
    for compilation in separate directory. Link against $(top_builddir)
    instead of $(top_srcdir) for the same reason.
    * doc/stencils/Makefile.am: Ditto.

2003-03-13  Julian Cummings  <[e-mail]>

	* blitz/range.h: Corrected my silly typo.
	* blitz/range.h: Modified Range::isAscendingContiguous() to return
	true for the case of a Range that contains just a single element,
	since this is a valid Range for constructing an Array.
2003-02-27  Patrick Guio <[e-mail]>
	* blitz/array/Makefile.am: Added newet-macros-old.h in the headers
	list to install.

2003-02-20  Julian Cummings  <[e-mail]>
	* blitz/bzdebug.h: Added BZ_DEBUG_PARAM macro to suppress argument
	name if it is only used within optional debugging code.  This will
	allow us to eliminate compiler warnings about unused parameters
	that occur when debugging code is disabled.  Also tidied up
	formatting of some of the other macro definitions.
	* blitz/array-impl.h: Use BZ_DEBUG_PARAM macro to eliminate
	compiler warnings about unused parameters that appear only in
	optional debugging code.
	* blitz/array/expr.h: Use BZ_DEBUG_PARAM macro to eliminate
	compiler warnings about unused parameters that appear only in
	optional debugging code.
	* blitz/array/stencils.cc: Use BZ_DEBUG_PARAM macro to eliminate
	compiler warnings about unused parameters that appear only in
	optional debugging code.
	* blitz/array/indirect.h: Use BZ_DEBUG_PARAM macro to eliminate
	compiler warnings about unused parameters that appear only in
	optional debugging code.
	* examples/rand2.cpp: Corrected mismatch between printf format
	string and argument type.
	* examples/tiny2.cpp: Include tinyvec-et.h header rather than
	tinyvec.h to get ET support.
	* examples/curldiv.cpp: Made some repairs to this example code so
	that it properly uses stencil ops.

2003-02-14  Julian Cummings  <[e-mail]>
	* testsuite/matthias-troyer-2.cpp: Uncommented line which applies
	the user-defined stencil.  With the recent fixes to
	blitz/array/stencilops.h, this code now works as expected.
	* blitz/array/stencilops.h: Changed A to (*A) as needed in stencil
	op definitions.  This is necessary because A is an iterator type,
	and the conversion operator is not automatically called when
	T_numtype is not a built-in type.  Also made stencil op
	definitions a bit more readable and fixed a typo in backward42
	multicomponent stencil.  Factorized the central difference
	expressions.
	* blitz/array/stencils.cc: Removed names of unused parameters in
	calcStencilExtent to eliminate gcc compiler warnings.
	* blitz/array/stencil-et.h: Removed name of unused parameter to
	eliminate gcc compiler warning.

2003-02-07  Julian Cummings  <[e-mail]>
	* blitz/indexexpr.h: Eliminated gcc compiler warnings about
	explicitly initializing base class ETBase in IndexPlaceholder copy
	constructor.
	* blitz/array/expr.h: Removed names of some unused parameters in
	_bz_ArrayExprConstant member functions to eliminate gcc compiler
	warnings.  Eliminated gcc compiler warnings about explicitly 
	initializing base class ETBase in _bz_ArrayExpr copy constructor.
	* blitz/array/reduce.h: Removed names of some unused parameters in
	_bz_ArrayExprReduce member functions to eliminate warnings from
	gcc compiler.
	* blitz/array/map.h: Removed names of unused parameters in some
	ArrayIndexMapping member functions to eliminate warnings from gcc.
	* blitz/array-impl.h: Removed names of unused parameters in
	slice() function to eliminate compiler warnings from gcc.
	Eliminated gcc compiler warnings about explicitly initializing 
	base classes MemoryBlockReference and ETBase in Array copy
	constructor.
	* blitz/array/slicing.cc: Removed name of an unused parameter in
	slice() function to eliminate a warning from gcc compiler.
	* blitz/array/iter.h: Removed name of unused Array parameter when
	constructing a ConstArrayIterator with a _bz_endTag specifier.
	Eliminates a warning from gcc.
	* blitz/benchext.cc: Changed type of some loop variables from int
	to unsigned to avoid comparisons between int and unsigned
	expressions.  Eliminated some unnecessary comparisons of unsigned
	quantities with zero.
	* blitz/benchext.h: Changed type of data members numParameters_
	and parameterNumber_ from int to unsigned, since these can never
	be negative.
	* blitz/array/stencils.cc: Removed names of unused parameters in
	function getStencilExtent() to eliminate gcc warnings.
	* blitz/meta/matassign.h: Removed names of some unused parameters
	in fully specialized versions of _bz_meta_matAssign::f() to
	eliminate gcc warnings.
	* blitz/blitz.h: Added "mutable" keyword (if available) to macro
	definition for declaring a mutex object.  Need to make mutex
	mutable when it is a member of a class with const member functions
	that use the mutex, as is the case with the MemoryBlock class when
	using threads.  This addresses a problem noted by Patrik Jonsson
	<[e-mail]>.

2003-02-05 Patrick Guio <[e-mail]>
        * depcomp install-sh mkinstalldirs missing: Removed from repository
	since generated running `autoreconf -v -i'.
	* Makefile.am: Added a guard to avoid overwriting COPYING and INSTALL
	files when running `autoreconf -v -i -f'.
	* benchmarks/Makefile.am doc/Makefile.am doc/examples/Makefile.am

	$prefix/info and  blitz.ps into $prefix/doc.
	* config.guess config.sub: Removed from repository. Added automatically
	when running `autoreconf -v -i' for recent versions of autoconf or copied

2003-01-22  Julian Cummings  <[e-mail]>

	* blitz/array/asexpr.h: Placed a guard around new
	BzUnaryExprResult and BzBinaryExprResult code so it is only used
	if compiler supports templates as template arguments.

	added prettyPrint template member function for class template _bz_negate,
	added condition BZ_HAVE_COMPLEX_MATH for the specialization of _bz_sqr for
	complex<T>.
	* blitz/generate/genmatuops.cpp: Undo blitz_isnan to isnan.
	* blitz/generate/genvecuops.cpp: Undo blitz_isnan to isnan.
