changelog

c++经典教材 Blitz++ v0.8

	* blitz/array/asexpr.h: Renamed class _bz_ArrayExprOp to
	_bz_ArrayExprBinaryOp for imporoved clarity.  Added static method
	getExpr() to asExpr class to convert the given type into the
	T_expr type needed for expression evaluation.  This allows us to
	reduce the number of specializations of binary operators by
	treating all ETBase<T> objects in a uniform fashion.

	* blitz/array/expr.h: Renamed class _bz_ArrayExprOp to
	_bz_ArrayExprBinaryOp for imporoved clarity.  Some other cosmetic
	changes as well.

	* blitz/array/bops.cc: Regenerated blitz/array/bops.cc header
	file.

	* blitz/array/uops.cc: Regenerated blitz/array/uops.cc header
	file.

	* blitz/generate/genarruops.cpp: Renamed _bz_ArrayExprOp class to
	_bz_ArrayExprBinaryOp for improved clarity.

	* blitz/generate/genarrbops.cpp: Renamed _bz_ArrayExprOp class to
	_bz_ArrayExprBinaryOp for improved clarity.

	* blitz/array/where.h: Removed some previously commented out code.
	Added Emacs C++ tag.
	* blitz/array/ops.cc: Replaced static_cast of ETBase objects with
	call to unwrap() member function.  Also removed external include
	guards.

	* blitz/array/newet-macros.h: Replaced static_cast of ETBase
	objects with call to unwrap() member function.  Also added Emacs
	C++ tag at top of file.

	* blitz/array/functorExpr.h: Replaced static_cast of ETBase
	objects with call to unwrap() member function.  Also added Emacs
	C++ tag and Blitz file header at top of file.

	* blitz/array/funcs.h: Replaced static_cast of ETBase objects with
	call to unwrap() member function.  Also added Emacs C++ tag at top
	of file and removed external include guards.

	* blitz/etbase.h: Added unwrap() member function to ETBase class
	that performs the static cast to produce the wrapped type.  Also
	added Emacs C++ tag at top of file.

	* doc/blitz.texi: Patch from Peter Bienstman to add directory info
	to this file, so it can be incorporated in a global texinfo index.

2003-12-17 Patrick Guio <[e-mail]>
	* doc/stencils/Makefile.am: Updated to make full use of libtool to
	compile stencil generator.

2003-12-16  Julian Cummings  <[e-mail]>

	* testsuite/newet.cpp: Added some testing of support for
	user-defined ternary functions.

	* blitz/array/Makefile.am: Removed newet-macros-old.h from
	array_HEADERS list.

	* blitz/array/newet-macros.h: Added macros
	BZ_DECLARE_ARRAY_ET_TERNARY, BZ_DECLARE_FUNCTION3, and
	BZ_DECLARE_FUNCTION3_RET to provide support for creating
	user-defined ternary functions that act on Arrays.  This code was
	originally provided by Navneet Dalal.  Also folded in to this file
	the macros from the file newet-macros-old.h, using the old
	versions only if template template arguments are not supported.  I
	will be eliminating newet-macros-old.h, since it contained many
	macros that were identical to the ones given here.
	* blitz/array/asexpr.h: Added definition of struct template
	BzTernaryExprResult, which provides the type of the result of a
	ternary operator or function acting on three Arrays.

	* blitz/array/expr.h: Added definition of class template
	_bz_ArrayExprTernaryOp to handle ternary operators and functions
	acting on blitz Arrays.  It is modeled after the where operator,
	which is a very special kind of ternary operator.

2003-12-15  Julian Cummings  <[e-mail]>

	* blitz/array/functorExpr.h: Added missing typename keyword (using
	_bz_typename macro) in a few places where derived types were being
	passed to the BZ_PROMOTE macro.

2003-12-12  Julian Cummings  <[e-mail]>

	* configure.in: Patch from Theodore Papadopoulo to test for flags
	needed to set the runtime library search path and to use dynamic
	linking.
	* acinclude.m4: Patch from Theodore Papadopoulo to provide
	functions that test for flags needed to set the runtime library
	search path and to use dynamic linking.
	* doc/Makefile.am: Patch from Theodore Papadopoulo to fix problem
	with building docs from a different directory than the source
	directory.

	_bz_explicit, and replaces them directly with the standard C++ 
	keywords.  These keywords should now be implemented in virtually all 
	C++ compilers, and this change makes the code much more standardized 
	and readable.  This patch also replaces class with typename when 
	specifying a template argument that is a type.  I have extended the 
	patch to the codes in the testsuite and examples subdirectories.

	* blitz/array/eval.cc: Fixed stack traversal evaluation routines
	to properly handle the case of negative strides.  Simply change
	comparison "i < ubound" to "i != ubound".  This fixes a bug
	reported quite a while ago regarding the failure of the copy()
	method when applied to a reversed Array.

2003-11-11  Julian Cummings  <[e-mail]>

	* blitz/array/newet-macros-old.h: Removed the superfluous
	combination of ETBase<T1> and T2.  If the first operand in a
	binary function or operator is not an Array, ArrayExpr or
	IndexPlaceholder, it is assumed to be a POD type.  The combination
	of T1 and ETBase<T2> handles all combinations of a POD type with a
	Blitz Array or Array-like type.
	* blitz/array/newet-macros.h: Removed the superfluous combination
	of ETBase<T1> and T2.  If the first operand in a binary function
	or operator is not an Array, ArrayExpr or IndexPlaceholder, it is
	assumed to be a POD type.  The combination of T1 and ETBase<T2>
	handles all combinations of a POD type with a Blitz Array or
	Array-like type.  Also cleaned up the file formatting.
	* blitz/array/Makefile.am: Removed newbops.cc from list of array
	header files for distribution.

	* blitz/Makefile.am: Added config-g++3.h to list of extra files to
	include in distribution.

2003-09-26 Patrick Guio <[e-mail]>
	* blitz/applics.h: Added TwoOperandApplicativeTemplatesBase's 
	_bz_Min and _bz_Max.
	* blitz/generate/genvecbfn.cpp: New file. Generate file blitz/vecbfn.cc
	with support for C=min(A,B) and C=max(A,B) for TinyVectors. min(A,B) and 
	max(A,B) return an elementwise min/max of two TinyVectors of same length.
	Comparable to STL min() and max() but rquires Blitz to be STL-compliant.
	* blitz/generate/genarrbops.cpp blitz/generate/genmatbops.cpp: Generate
	support for min() and max() applics.
	The min() and max() are elementwise as for TinyVectors. Now available for
	Array, Matrix and Vector.
	* blitz/generate/Makefile.am: Added necessary stuff for the generation of
	blitz/vecbfn.cc from blitz/generate/genvecbfn.
	* blitz/array/ops.h blitz/array/newbops.cc: Added elementwise min() and
	max() functions for the new ET for Arrays.
	* blitz/vecbfn.cc blitz/array/bops.cc blitz/matbops.h: 
	Regenerated with support for elementwise min() and max().


2003-09-17  Julian Cummings  <[e-mail]>

	* compiler/Makefile.am: Separate targets for local config.h file
	and the BZ_CONFIG_H file in blitz/config.h.  The distribution
	contains a default blitz/config.h file, but this should be rebuilt
	when the distribution is first unpacked.
	* doc/stencils/Makefile.am: Removed texinfo files from EXTRA_DIST
	list, since these files are included in the distribution by the
	parent directory already.
	* doc/examples/Makefile.am: Removed source code files for examples
	from EXTRA_DIST, since SOURCES get included in distribution
	automatically.  Added a few missing files to the EXTRA_DIST list.
	* doc/Makefile.am: Added files containing figures for the
	documentation to the distribution.
	* doc/version.texi: Updated date in version.texi file.
	* Makefile.am: Added manual to list of SUBDIRS to be processed by
	automake.  This is needed to include source files for the Blitz
	html manual in the distribution.
	* random/Makefile.am: Removed Makefile.am from list of header
	files for subdirectory random.  This file is part of the
	distribution but not part of the installation.
	* benchmarks/Makefile.am: Comment out the compile target, so that
	it is not included in distdir target.  We don't need to compile
	benchmark codes in order to create a distribution.
	* blitz/Makefile.am: Added file config-VS.NET2003.h to EXTRA_DIST
	for inclusion in distribution.
	* Makefile.am: Deleted old file config.h.in from EXTRA_DIST list
	and added new files README-VS.NET and Blitz-VS.NET.zip for
	inclusion in distribution.
	* configure.in: Switched the optimization flag for the SGI CC
	compiler back to -Ofast instead of -O3.  This setting includes the
	-IPA option, which seems to make a large difference in code
	performance.  Also, using the -IPA option does not seem to cause
	problems when using a static libblitz.a, which is now once again
	the default behavior of the configure script.  Also, bumped the
	version number to 0.7 in anticipation of a new tarball
	distribution.

2003-09-09  Julian Cummings  <[e-mail]>

	* configure.in: Activated automake macro that disables building of
	shared libraries by default.  Shared libraries support can be
	turned on with the --enable-shared option.  Changed SGI compiler
	default optimization flag from -Ofast to -O3 to avoid issues with
	the use of interprocedural analysis (-IPA) during compilation and
	linking.  Removed some defunct compiler options such as KCCdev and
	the old API-specific SGI32 and SGI64 options (use --enable-64bit
	instead).  Removed linking with SGI libCio.a, which should now be
	obsolete.  Deleted a few unused autoconf/automake macros.
	Corrected instruction message at end of script.

	* blitz/vecexpr.h: Corrected a dependency problem noted by
	Matthias Schillinger that was causing some test codes to fail to
	compile.  This is an example of the problem with having ET support
	for the Vector and TinyVector types convolved together.

2003-09-08  Julian Cummings  <[e-mail]>

	* blitz/rand-mt.h: Replaced use of &S[0] syntax with call to
	S.begin() to avoid issues with the return type of
	std::vector<>::operator[].  Added call to reload() at the end of
	the seed() function.
	* blitz/tinyveciter.h: Changed from use of unsigned to int type to
	avoid gcc compiler warnings about comparisons between unsigned and
	signed integer types.  Extended BZPRECONDITION checks to test that
	int argument value is non-negative.

2003-09-02  Julian Cummings  <[e-mail]>

	* blitz/array/methods.cc: Fixed bug in code that constructs an
	Array from an array expression.  The default value for the
	ordering and ascending variables when there is no Array with a
