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/null.cxx: Define cyg_check_data/func_ptr() with const args.
	* src/buffer.cxx: 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]>

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]>

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.

	* 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]>

	the MLQ scheduler and alarm objects.

2000-12-15  Nick Garnett  <[e-mail]>

	* include/clist.hxx: Added this implementation of simple circular
	list classes. This is not immediately useful, except to the

	* include/cyg_type.inc: Create. Used for the equivalent stuff of
	cyg_type.h in assembler and linker scripts

2000-07-19  Jonathan Larmour  <[e-mail]>

	* src/pkgstart.cxx (cyg_package_start): Remove POSIX startup option
	* cdl/startup.cdl: Likewise

2000-07-18  Jonathan Larmour  <[e-mail]>

	* src/buffer.cxx (increment_buffer_pos): Reset buffer pos *before*
	we try to print the buffer
	Thanks to Chris Morrow (cmorrow at YottaYotta.com ) for spotting
	the problem.

2000-07-04  Jonathan Larmour  <[e-mail]>

	* cdl/infra.cdl: Add CYGFUN_INFRA_EMPTY_DELETE_FUNCTIONS option

	_stext and _etext.

	define labels without an extra underscore. This reflects the
	practice of most of the targets we support.

	* include/cyg_type.h:
	Added CYGBLD_ATTRIB_SECTION to assign variables to a named
	section.
	Added CYG_LABEL_DEFN() macro for defining labels in asm and linker
	scripts. This is particularly useful for generating labels in
	inline assembler fragments.

2000-05-02  Jonathan Larmour  <[e-mail]>

	* cdl/startup.cdl:
	* src/pkgstart.cxx:
	Remove CYGSEM_START_ISO_C_COMPATIBILITY: startup is now handled
	via extras.o
	* include/cyg_type.h: Define __externC alternative to externC

2000-02-28  Gary Thomas  <[e-mail]>

	* include/diag.h: 
	* src/diag.cxx (diag_dump_buf): Add diagnostic "dump buffer" function.

2000-02-21  Hugo Tyson  <[e-mail]>

	* src/tcdiag.cxx (cyg_test_is_simulator): set this true if ugly
	new cdl_option CYGHWR_TARGET_SIMULATOR_NO_GDB_WORKING is set.
	This means we cannot diddle the variable using GDB.

2000-02-18  Hugo Tyson  <[e-mail]>

	* src/tcdiag.cxx (cyg_test_exit): Add the facility for a platform
	HAL to define an action to take at CYG_TEST_EXIT time; this is
	useful for some simulators that are not (yet) Gdb integrated.
	The action is CYGHWR_TEST_PROGRAM_EXIT() if defined.

	* src/simple.cxx (cyg_assert_fail): Add the facility for a
	platform HAL to define an action to take when an assertion failure
	occurs.  Ditto.

	* src/fancy.cxx (cyg_assert_fail): Ditto.

	* src/buffer.cxx (cyg_assert_fail): Ditto.

	[no change to null.cxx because, well, it's null isn't it]

2000-02-08  Jonathan Larmour  <[e-mail]>

	* include/cyg_trac.h: Define and document CYG_TRACE_PRINT() and
	CYG_TRACE_DUMP() macros for outputting buffered trace output, and
	kernel state dump respectively

	* cdl/debug.cdl (CYGDBG_INFRA_DEBUG_TRACE_ASSERT_BUFFER): 
	replace (incorrect) mention of cyg_trace_output() with CYG_TRACE_PRINT()
	macro.

	* src/fancy.cxx (cyg_trace_dump): Add (from buffer.cxx)
	* src/simple.cxx (cyg_trace_dump): Add (from buffer.cxx)
	* src/null.cxx (cyg_trace_dump): Add as empty function

2000-01-31 Simon FitzMaurice  <[e-mail]>
  * cdl\infra.cdl:

  Adjust help URLs in line with new doc layout.

2000-01-28 Simon FitzMaurice  <[e-mail]>
  * cdl\infra.cdl:

  Adjust help URLs in line with new doc layout.

1999-11-26  Gary Thomas  <[e-mail]>

	* include/cyg_type.h: Add MLT symbols CYGMEM_REGION_ATTR_R/W.

1999-11-23  Hugo Tyson  <[e-mail]>

	* cdl/debug.cdl: Add "active_if CYGDBG_USE_TRACING" to all tracing
	only options in the buffered flavour of assert'n'trace.  Otherwise
	enabling asserts but no tracing does not build; oldCDL dealt with
	this by a string of ifdefs in the header.  Active_if is my friend.
	This also prevents the confusion of having active options that
	have no effect whatsoever.
	Aside: the default is buffered assert'n'trace so that the test
	farm can enable tracing and not get swamped by output.

1999-05-14  Hugo Tyson  <[e-mail]>

	* include/cyg_type.h (CYG_INIT_COMPAT): add a new init priority
	level for compatibility layers (for uITRON that is, but
	potentially POSIX also perhaps, after libc anyway).

1999-04-14  John Dallaway  <[e-mail]>

	* include/pkgconf/infra.h: Add cdl_package doc attribute.

1999-04-12  Jesper Skov  <[e-mail]>

	* include/cyg_type.h: Added new init priority for IO devices.

	* include/diag.h: 
	* src/diag.cxx: 
	Use device for diag if configured so.

1999-03-19  Gary Thomas  <[e-mail]>

	* src/diag.cxx (diag_vprintf): Support '%%' printf modifier.

1999-03-05  Jonathan Larmour  <[e-mail]>

	* include/cyg_type.h:
	Add CYGBLD_ATTRIB_CONST and tidy define indentation

1999-03-04  Bart Veer  <[e-mail]>

	* include/diag.h:
	Added a #include for <pkgconf/infra.h> so that the header file
	can correctly check for CYGDBG_INFRA_DIAG_PRINTF_USE_VARARG
