A C++ class library for scientific computing

2004-10-26  Patrick Guio  <[e-mail]>

	* doc/Makefile.am: Assigned variable docdir the value
	$(prefix)/doc/$(PACKAGE) in order to gather blitz documentation in a
	subdirectory of the generic doc directory.
	* doc/doxygen/Makefile.am: New variable docdir assigned the value
	$(prefix)/doc/$(PACKAGE)/doxygen. Used when installing doxygen-generated 
	documentation in install-data-hook and make-install-dirs targets.

2004-10-26  Julian Cummings  <[e-mail]>

	* doc/Makefile.am: Added blitz.dvi to EXTRA_DIST, so we don't need
	to rebuild it from the blitz.texi file after unpacking the
	distribution tarball.

2004-10-25  Julian Cummings  <[e-mail]>

	* blitz/generate/Makefile.am: Move header-generating programs to
	EXTRA_PROGRAMS so they are not built by the default target.  They
	will only be built if a generated header file needs to be updated.
	* blitz/generate/Makefile.am: Made generated header files depend
	directly on the source code file needed to generate header, rather
	than the executable.  Modified build rules for generated headers
	to build executable first and then run it to create header.  This
	should allow the tarball distribution to skip generation of header
	files if they are already provided in distribution and are
	up-to-date.

	* doc/examples/Makefile.am: Made .out output files depend on .cpp
	source file rather than executable.  Modified build rule for
	output files to first build executable, then run it to produce
	output file.  With these changes, the tarball distribution can use
	the given output files without having to rebuild all the
	executables.

	* doc/Makefile.am: Added HTML and image files to doc_DATA and to
	EXTRA_DIST, so HTML documentation will be installed and included
	in distribution tarball.

2004-10-22  Patrick Guio  <[e-mail]>

	* doc/Makefile.am: Added blitz.info and blitz.pdf in EXTRA_DIST.  
	Those files ought to be in the dist tarball since they might not be able
	to be regenerated due to not available 'tex' and 'makeinfo' commands.
	Added blitz.ps and blitz.pdf in doc_DATA since they are now distributed.
	* doc/doxygen/Makefile.am: Removed search option '-s' for doxytag and
	replaced by tag option '-t' since '-s' is deprecated in recent doxygen
	version.

2004-10-21  Julian Cummings  <[e-mail]>

	* doc/Makefile.am: Added new PDF versions of the figures to
	EXTRA_DIST.  Moved blitz.ps from doc_DATA to EXTRA_DIST, so that
	TeX is not required for installation.

2004-10-16  Julian Cummings  <[e-mail]>

	* .cvsignore: Removed _configs.sed.  This file is no longer
	created.
	* m4/ax_prefix_config_h.m4: Removed line that copied sed script to
	_configs.sed.  The sed script is not needed after the
	AX_PREFIX_CONFIG_H macro has executed.

2004-10-15  Julian Cummings  <[e-mail]>

	* doc/Makefile.am: Added doxygen to SUBDIRS list.  Added build
	rules for blitz_TEXINFOS files in stencils and examples
	subdirectories.  This is needed so that the top-level dist-gzip
	build target can work properly.
	* doc/platforms.texi: Updated information on various
	platforms/compilers.  Current info on Intel and GNU compilers.
	Added section on Microsoft VS.NET 2003.  Noted that support for
	Metrowerks and Cray C++ compiler is no longer being maintained.
	* doc/install.texi: Updated installation and porting instructions
	to refer to current approach using autoconf and configure script.
	* doc/version.texi: Updated version info.
	* blitz/README: Added note and caveat about the new
	compiler-specific header file.
	* blitz/Makefile.am: Removed the EXTRA_DIST list, since it
	referred to files that are no longer in the distribution.
	* configure.ac: Bumped version number to 0.8.  Added icc to list
	of program names for C++ compiler that we try.  This name of the
	Intel C++ compiler is now deprecated in favor of the name icpc,
	which we try first.

2004-10-14  Julian Cummings  <[e-mail]>

	* configure.ac: Modification suggested by Derrick Bass
	([e-mail]) that disables use of the F90 compiler if it
	does not support free format source code or source code files with
	a .f90 extension.
	* testsuite/newet.cpp: Fixed typo reported by Derrick Bass
	([e-mail]).

2004-10-14  Patrick Guio  <[e-mail]>

	* config/texinfo.tex: Removed from repository since it is generated
	when running 'autoreconf -vif'.

	* doc/blitz.info: Removed from repository since it is generated when
	making doc.


2004-10-13  Patrick Guio  <[e-mail]>

	* m4/ac_compiler_specific_header.m4: New macro "extracted" from
	configure.ac to set the compiler-specific header. Added 
	COMPILER_SPECIFIC_HEADER as a precious variable. Added icc as a
	supported compiler (together with icpc).

	* configure.ac: Moved compiler specific-header handling in
	m4/ac_compiler_specific_header.m4.

	* blitz/config-ICL.h blitz/config-KCC.h blitz/config-SC4.0.h
	blitz/config-SGi.h blitz/config-g++2.7.2.h blitz/config-g++3.h
	blitz/config-mwerks.h blitz/config-xlC.h: Removed as rendered
	obsolete due to the new form of preprocessor symbol BZ_HAVE_*.


2004-10-06  Julian Cummings  <[e-mail]>

	* blitz/Makefile.am: Modified to install the compiler-specific
	header file that was created.  Added definition of EXTRA_HEADERS
	with list of all possible header files of this sort.  Seems to be
	required by automake.

	* configure.ac: Modified compiler-specific header file logic to
	define the name of the header file that is produced as
	COMPILER_SPECIFIC_HEADER.  We need this in order to tell the blitz
	subdirectory Makefile which header to install.
	* random/mt.h: Changed BZ_NAMESPACES to BZ_HAVE_NAMESPACES.
	* examples/cfd.cpp: Changed BZ_NAMESPACES to BZ_HAVE_NAMESPACES.
	* examples/simple.cpp: Use blitz macro for using directive.
	* examples/slicing.cpp: Use blitz macro for using directive.
	Changed BZ_PARTIAL_ORDERING to BZ_HAVE_PARTIAL_ORDERING.
	* examples/tiny.cpp: Use blitz macro for using directive.
	* examples/transform.cpp: Use blitz macro for using directive.
	* examples/where.cpp: Use blitz macro for using directive.
	* testsuite/complex-test.cpp: Changed BZ_HAVE_COMPLEX_MATH to
	BZ_HAVE_COMPLEX_FCNS.

	* testsuite/promote.cpp: Changed to new form of preprocessor
	symbols.

	* blitz/generate/genvecuops.cpp: Changed to new form of
	preprocessor symbol for complex<T> methods.

	* blitz/generate/genmathfunc.cpp: Changed one more instance of
	BZ_HAVE_COMPLEX_MATH to BZ_HAVE_COMPLEX.

	* blitz/array/newet-macros.h: Changed preprocessor symbols to new
	form.

	* blitz/array/multi.h: Changed BZ_HAVE_COMPLEX_MATH to
	BZ_HAVE_COMPLEX.

	* blitz/array/funcs.h: Changed BZ_HAVE_COMPLEX_MATH to
	BZ_HAVE_COMPLEX_FCNS.

	* blitz/array/asexpr.h: Changed preprocessor symbols to new form.
	* blitz/promote.h: Changed BZ_ preprocessor symbols to new form.
	* blitz/numtrait.h: Changed BZ_BOOL to BZ_HAVE_BOOL.
	* blitz/generate/genmathfunc.cpp: Fixed up usage of various
	preprocessor symbols related to complex type and math functions.
	* blitz/funcs.h: Fixed up usage of various preprocessor symbols
	related to complex type and math functions.
	* blitz/array-impl.h: Changed BZ_PARTIAL_ORDERING to
	BZ_HAVE_PARTIAL_ORDERING.

	* blitz/bzdebug.h: Changed BZ_RTTI to BZ_HAVE_RTTI and added use
	of BZ_HAVE_STDLIB_H.

	* blitz/Makefile.am: Replaced config.h with bzconfig.h in
	blitz_HEADERS list.

	* blitz/compiler.h: Use new master file <blitz/bzconfig.h> to
	include a compiler-specific config file.  Use new version of
	preprocessor symbols defined by autoconf macros.
	* m4/ac_check_cxx_features.m4: Removed superfluous include guard
	insertion into config.h file.  Autoconf already adds such an
	include guard.

	* m4/ac_cxx_general.m4: Changed AC_CXX_NAMESPACE to standard
	AC_CXX_NAMESPACES.

	* m4/ac_cxx_standard_library.m4: Replacing autoconf macro
	AC_CXX_HAVE_COMPLEX_MATH with AC_CXX_HAVE_COMPLEX_FCNS and two
	macros from the GNU autoconf macro archive,
	AC_CXX_HAVE_COMPLEX_MATH1 and AC_CXX_HAVE_COMPLEX_MATH2.  The
	AC_CXX_HAVE_COMPLEX_FCNS macro tests only for the standard methods
	of the complex<T> class such as real() and conj().  The math
	function tests are now handled by the standard macros from the GNU
	autoconf macro archive.
	* m4/ac_cxx_type_promotion.m4: Added a real program to properly
	test for the vector type promotion mechanism.  Modified to follow
	format of m4 macros in GNU autoconf macro archive.  Defines
	HAVE_TYPE_PROMOTION instead of BZ_HAVE_TYPE_PROMOTION.  The BZ_
	prefix will be added using the AX_PREFIX_CONFIG_H autoconf macro.

	* m4/ac_cxx_nceg_restrict_egcs.m4: Modified to follow format of m4
	macros in GNU autoconf macro archive.  The BZ_ prefix will be
	added to the defined preprocessor symbol using the
	AX_PREFIX_CONFIG_H autoconf macro.

	* m4/ac_cxx_math_fn_in_namespace_std.m4: Modified to follow format
	of m4 macros in GNU autoconf macro archive.  The BZ_ prefix will
	be added to the defined preprocessor symbol using the
	AX_PREFIX_CONFIG_H autoconf macro.

	* m4/ac_cxx_have_rusage.m4: Modified to follow format of m4 macros
	in GNU autoconf macro archive.  Defines HAVE_RUSAGE instead of
	BZ_HAVE_RUSAGE.  The BZ_ prefix will be added using the
	AX_PREFIX_CONFIG_H autoconf macro.

	* m4/ac_cxx_have_climits.m4: Modified to follow format of m4
	macros in GNU autoconf macro archive.  Defines HAVE_CLIMITS
	instead of BZ_HAVE_CLIMITS.  The BZ_ prefix will be added using
	the AX_PREFIX_CONFIG_H autoconf macro.

	* m4/ac_cxx_flags_preset.m4: Added default flag settings for xlc++
	compiler, which is a version of the IBM C++ compiler made for
	Darwin systems.  Added -D flags for the IBM and Fujitsu compilers
	so we can detect use of these compilers at compile time.  Most
	other C++ compilers already define a distinctive preprocessor
	symbol.

2004-10-05  Julian Cummings  <[e-mail]>

	* compiler/promote.cpp: This file contained an empty program, so I
	wrote an actual test for the vector type promotion mechanism using
	traits, as described in "Using C++ Traits Classes for Scientific
	Computing" by Todd Veldhuizen (1996).
2004-10-01  Julian Cummings  <[e-mail]>

	* blitz/array/indirect.h: Changes corresponding to those recently
	made in cartesian.h and eval.cc.  Extended indexSet() method to
	accept up to 11 parameters.  Replaced data[i] with *data++ in
	expression evaluation loops using unit stride.

2004-09-17  Julian Cummings  <[e-mail]>

	* manual/Makefile.am: Corrected name of arrays-types.yo file.
	Added README file to EXTRA_DIST.  Moved all of the .yo files and
	the helper files used to create the old blitz manual from doc_DATA
	to EXTRA_DIST.  We install only the old blitz manual itself from
	this directory.  It is no longer maintained.

	* blitz/array/eval.cc: Replaced data[i] with *data++ in unit
	stride loops over data inside various Array expression evaluation
	mechanisms.  This tends to optimize better under some compilers,
	and this change eliminates some unusual bugs in expression
	evaluation when using the KCC compiler in optimized mode.  This is
	an old patch which I forgot to check in.
	* blitz/array/resize.cc: Changed precondition on resize() method
	to allow extent arguments with the value 0.  This will allow the
	user to resize an existing Array to size 0, which will cause the
	MemoryBlockReference class to call the changeToNullBlock() method
	and release its reference to any pre-existing allocated memory
	block.  We continue to reject an extent of 0 in the
	resizeAndPreserve() method, since presumably the user wishes to
	preserve some pre-existing elements.
	* blitz/array/slicing.cc: Use default value of zero for second
	argument in call to changeBlock method of class
	MemoryBlockReference.  No need to set data_ pointer to
	array.dataZero(), as this is already done by changeBlock.
	* blitz/array/methods.cc: Use default value of zero for second
	argument in call to changeBlock method of class
	MemoryBlockReference.  Removed commented out line setting
	data_=array.data_, as this is now already taken care of by
	changeBlock.  When constructing an Array, only allocate new memory
	block if numElements>0.  If numElements==0, call
	changeToNullBlock.  This ensures that the begin() and end()
	iterators are equal for an Array with size 0.
	* blitz/vector.cc: Use default value of zero for second argument
	in call to changeBlock method of class MemoryBlockReference.
	* blitz/memblock.h: Reset data_ pointer equal to data_ pointer of
