2007-12-28  Oyvind Harboe <[e-mail]>
	
	* src/memcpy.cxx: added assert when memory areas for memcpy()
	overlaps => result is undefined. It is important to catch *all*
	cases of this if adding an optimisation for unaligned copy.
	
2007-06-28  Gary Thomas  <[e-mail]>

	* src/tcdiag.cxx: 
	* src/diag.cxx: Add (char *) casts to make GCC 4.2.x happy.

2007-05-31  Rutger Hofman <[e-mail]>

	* src/diag.cxx: when printing a long long, should not truncate
	its value to a long or int size

2006-10-26  Stefan Sommerfeld <[e-mail]>

	* include/cyg_types.h: fixed typo, __GNU_PATCHLEVEL__ was checked,
	should be __GNUC_PATCHLEVEL__ (which is already used later)
	* include/cyg_types.h: fixed comment for CYGBLD_ATTRIB_USED, wrong
	GCC version was referenced

2006-08-25  Gary Thomas  <[e-mail]>

	* cdl/infra.cdl: 
	CYGNUM_INFRA_EMPTY_DELETE_THRESHOLD must be 'data', not 'boolean'

2006-05-17  David Vrabel <[e-mail]>
 
	* include/cyg_type.h: #define CYG_NELEM to calculate the
 	number of elements in a (statically allocated) array.
 
2006-05-08  Sergei Gavrikov <[e-mail]>
	
	* src/buffer.cxx: Fix the compiler warnings.

2005-11-04  Bart Veer <[e-mail]>
	
	* tests/cxxsupp.cxx: Fix the compiler warnings.

2005-10-16  Andrew Lunn  <[e-mail]>

	* src/delete.cxx: 
	* cdl/infra.cdl: Count the number of calls to delete when
	INFRA_DEBUG is enabled. If the threshold is exceeded it probably
	means the user expects a real delete function, not the empty one.
	
2005-10-12  Laurent Gonzalez  <[e-mail]>

	* src/simple.cxx (cyg_check_func_ptr): match the implementation to
	the prototype. This got forgotten in the last patch.
	
2005-07-29  Andrew Lunn  <[e-mail]>

	* include/cyg_ass.h: Fixed a function prototype so that
	gcc4 does not give warnings. A const void makes no sense.
	* src/*.cxx (cyg_check_func_ptr): match the implementation to the
	prototype.

2005-06-27  Andrew Lunn  <[e-mail]>

	* include/cyg_type.h: Added CYGBLD_ATTRIB_USED so that we can
	indicate to gcc 3.4.4 or above not to throw away a variable or
	function even when it appears to be not references.
	
2005-03-27  Andrew Lunn  <[e-mail]>

	* include/diag.h: Added CYGBLD_ATTRIB_PRINTF_FORMAT where
	appropriate to get the compiler to do more checking.
	* src/diag.cxx (diag_dump_buf_with_offset_16bit): Fix compiler warning
	caused by above change.

2005-02-08  Andrew Lunn  <[e-mail]>

	* tests/diag_sprintf1.c 
	* tests/diag_sprintf2.c
	* cdl/infra.cdl: Used the sprintf test from libc to test 
	  diag_sprintf.

2005-02-08  Christoph Csebits <[e-mail]>

	* src/diag.cxx (diag_snprintf): Off by one error could cause the
	end of the buffer to be overrun.

2004-07-12  Gary Thomas  <[e-mail]>

	* src/diag.cxx (_vprintf): Fix return length for %%

2004-06-30  Gary Thomas  <[e-mail]>

	* src/diag.cxx (_vprintf): Returned [length] was wrong for %p

2004-04-16  Jonathan Larmour  <[e-mail]>

	* tests/cxxsupp.cxx: Allow inline function to be correctly inlined.

2004-04-15  Jonathan Larmour  <[e-mail]>

	* include/cyg_type.h: added CYG_ATTRIB_ALIGN_MAX and
	CYGBLD_ATTRIB_ALIGNOFTYPE. Inspired by Robert Larice.
	
2004-01-08  Jani Monoses <[e-mail]>

	* src/diag.cxx (diag_check_string): Allow '\t' in format strings.
	
2004-01-05  Gary Thomas  <[e-mail]>

	* tests/fc_test.c: 
	* src/tcdiag.cxx (cyg_assert_msg): 'fconfig' API changed again.

2003-12-21  Gary Thomas  <[e-mail]>

	* tests/fc_test.c: New test/demonstration of 'fconfig' access.

	* src/tcdiag.cxx (cyg_assert_msg): Interface to 'fconfig' data
	has changed.

2003-10-11  Gary Thomas  <[e-mail]>

	* src/tcdiag.cxx (cyg_test_exit): 
	* cdl/infra.cdl: New option CYGSEM_INFRA_RESET_ON_TEST_EXIT which
	[if defined] indicates that "cyg_test_exit()" should reset the 
	platform instead of the default hang.

2003-10-03  Nick Garnett  <[e-mail]>

	* tests/cxxsupp.cxx: Added ifdef to disable this test on H8/300
	targets. The H8/300 toolchain does not currently have C++ support.

2003-07-01  Michael Checky  <[e-mail]>

	* src/diag.cxx: Added support for the 'z' qualifier in format strings.

2003-05-05  Gary Thomas  <[e-mail]>

	* cdl/infra.cdl: Add option to control number of times tests run.

2003-04-25  Jonathan Larmour  <[e-mail]>

	* tests/cxxsupp.cxx: don't include <pkgconf/kernel.h> as it's not
	needed.
	(cyg_start): CYGINT_ISO_MALLOC needs a #if test.

2003-04-10  Nick Garnett  <[e-mail]>

	* tests/cxxsupp.cxx: Added this test program to check that basic
	C++ support is present. It checks that pure virtual functions can
	be defined, that new and delete are present and functional, and
	that calls to as-yet undefined inline functions work. Most of
	these are linker and runtime system issues, so the actual run of
	the program is almost a non-event.

	* cdl/infra.cdl:
	Added CYGFUN_INFRA_DUMMY_ABORT and CYGFUN_INFRA_DUMMY_STRLEN
	options to control inclusion of dummy abort() and strlen()
	functions. These are needed to be present by the compiler's C++
	runtime system, although they should never be called.
	Added CYGPKG_INFRA_TESTS to define test programs.
	Added CYGPKG_INFRA_LDFLAGS_REMOVE and CYGPKG_INFRA_LDFLAGS_ADD to
	modify the linkage options for the infra package
	tests. Specifically they remove the --gc-sections option and make
	all linker warning fatal. This is necessary if cxxsupp.cxx is to
	test what it needs correctly.
	
	* src/abort.cxx: Added this dummy implementation of abort() to
	satisfy references in the C++ runtime system.

	* src/strlen.cxx: Added this dummy implementation of strlen() to
	satisfy references in the C++ runtime system.

2003-03-27  Bart Veer  <[e-mail]>

	* src/pure.cxx, cdl/infra.cdl: new function __cxa_pure_virtual(),
	needed when building with g++ v3.x if the code uses pure
	virtual functions.

2003-01-18  Jonathan Larmour  <[e-mail]>

	* include/cyg_ass.h (CYG_CHECK_FUNC_PTRC): Define with const pointer
	arguments.
	(CYG_CHECK_DATA_PTRC): Ditto. 
	(CYG_CHECK_FUNC_PTR): Ditto. 
	(CYG_CHECK_DATA_PTR): Ditto.

	* src/fancy.cxx: Ditto.
	* src/simple.cxx: Ditto.

2002-07-18  Gary Thomas  <[e-mail]>

	* include/diag.h: 
	* src/diag.cxx (diag_vdump_buf_with_offset): New function.

2002-05-22  Jesper Skov  <[e-mail]>

	* cdl/infra.cdl: Added two options to control CFLAGS.

2002-05-17  Martin Buck <[e-mail]>
 
 	* include/cyg_type.h (CYGBLD_ATTRIB_PRINTF_FORMAT): Add.
 
2002-05-23  Gary Thomas  <[e-mail]>

	* src/diag.cxx (_vprintf): Mapping of '\n'=>'\r\n' must be done
	at the _putc() level.

	* src/diag.cxx (diag_dump_buf_with_offset): Fix pad for short lines.

	* src/diag.cxx: Return proper length result for sprintf() functions.

2002-04-09  Jonathan Larmour  <[e-mail]>

	* include/cyg_type.h: Allow HALs to override certain attrib macros.

2002-02-19  Gary Thomas  <[e-mail]>

	* src/diag.cxx (diag_snprintf): 
	* include/diag.h: Change function signature on diag_snprintf()
	to match snprintf() found in stdio.

2002-02-13  Jonathan Larmour  <[e-mail]>

	* include/cyg_trac.h: Make message type of trace functions be
	const char * to help avoid warnings with callers.
	* src/null.cxx: Reflect that in actual functions.
	* src/fancy.cxx: Ditto.
	* src/simple.cxx: Ditto.
	* src/buffer.cxx: Ditto.

2002-01-31  Hugo Tyson  <[e-mail]>

	* src/tcdiag.cxx (cyg_assert_msg): Enable this function
	universally; given the extra usefulness it now has (see below)
	it's worth always having around by default in asserted builds.
	It can be disabled with CYGDBG_INFRA_DEBUG_ASSERT_MESSAGE = 0.

2002-01-30  Hugo Tyson  <[e-mail]>

	* src/tcdiag.cxx (cyg_assert_msg): Collect from RedBoot flash

2002-01-23  Jonathan Larmour  <[e-mail]>

	* include/cyg_type.h: Define CYG_INIT_IO_FS used by filesystems
	so that they init *after* the devices they depend on.

2002-01-21  Jonathan Larmour  <[e-mail]>

	* src/tcdiag.cxx (cyg_test_exit): Work around problem with recent
	SH tools that isn't likely to get fixed soon.

2002-01-17  Jeroen Dobbelaere  <[e-mail]>

	* src/diag.cxx (diag_check_string): enlarge valid string length to 2048

2001-12-06  Jesper Skov  <[e-mail]>

	* src/diag.cxx: Added functions to do memory dump in 16 and 32 bit
	units. Based on changes from Warren Jasper <[e-mail]>.
	* include/diag.h: Function declarations.
	
2001-09-12  Jonathan Larmour  <[e-mail]>

	functions better.

	* src/diag.cxx (diag_check_string): Also accept \b.

2001-08-25  Gary Thomas  <[e-mail]>

	* src/diag.cxx: 
	* include/diag.h: 
	* cdl/infra.cdl: Restructuring to support more flexible versions
	of diag_printf() and related functions.  Remove old cruft which
	was workaround for possibly failing compilers [K&R support].
	These versions of printf(), etc, were part of the RedBoot package
	and have been moved here (and renamed) to reduce code duplication.

2001-08-22  Jonathan Larmour  <[e-mail]>
