eCos/RedBoot for勤研ARM AnywhereII(4510) 含全部源代码

1998-12-21  Bart Veer  <[e-mail]>

	* include/cyg_type.h:
	Allow for platforms where pointers are not 32 bits wide.
	
1998-12-16  Hugo Tyson  <[e-mail]>

	* include/testcase.h (cyg_test_is_simulator): 
	* src/tcdiag.cxx (cyg_test_is_simulator): 
	Change the type to int so that all gdb's understand it.
	(it was impossible to assign to from the prompt as a bool)

1998-12-09  Bart Veer  <[e-mail]>

	* include/testcase.h:
	Hide a __noreturn__ attribute inside a macro so that the
	header file can be used for host-side code.

1998-11-02  Jesper Skov  <[e-mail]>

	* src/memset.c (_memset): Use type casted pointer to avoid
	compiler warning.

Mon Oct 26 21:20:13 1998  Jonathan Larmour  <[e-mail]>

	* src/buffer.cxx: 
	Make write_thread_id() conditional on CYGDBG_USE_ASSERTS as that's
	the only time it is used. This silences a compiler warning

Mon Oct 26 19:40:48 1998  Jonathan Larmour  <[e-mail]>

	* src/memset.c, src/memcpy.c:
	Conditionalise out all tracing for now
	Fix for PR 17996

Fri Oct 23 05:42:36 1998  Jonathan Larmour  <[e-mail]>

	* include/cyg_ass.h (CYGASSERT_docall): 
	Make a dummy reference to _msg_ argument when
	CYGDBG_INFRA_DEBUG_ASSERT_MESSAGE is disabled, otherwise we may get
	"unused variable" warnings
	Fix for PR 17889

1998-10-22  Hugo Tyson  <[e-mail]>

	* src/buffer.cxx (increment_buffer_pos): 
	Use the correctly named print_trace_buffer() rather than some
	typo/globaleditto.
	(cyg_trace_dump): only refer to thread->get_saved_context() if
	CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT is defined.

1998-10-22  Hugo Tyson  <[e-mail]>

	* src/buffer.cxx (write_thread_id): 
	Make get_tid() be there when used.

	* include/pkgconf/infra.h: 
	Only enable all the buffered tracing stuff if USE_TRACING is
	selected; otherwise link errors ensue if only USE_ASSERTS is
	enabled.

1998-10-22  Jesper Skov  <[e-mail]>
        PR 17914

	* src/simple.cxx (CYG_NO_THREADID): Set if there is no Kernel
	support.

1998-10-20  Nick Garnett  <[e-mail]>

	* src/null.cxx:
	Removed fix for PR 17471 since the required macros have been moved
	to cyg_type.h.

	* include/diag.h (diag_printf):
	* src/diag.c (diag_printf):
	Made use of variadic arguments optional in this function.

	* include/pkgconf/infra.h:
	Added configury to support buffered tracing.

	* src/fancy.cxx (trim_func):
	Fixed fencepost bug.

	* src/PKGconf.mak:
	* src/buffer.cxx:
	Added buffer.cxx to implement buffered trace log.

Thu Oct 15 21:27:23 1998  Jonathan Larmour  <[e-mail]>

	* src/delete.cxx, src/memcpy.c, src/memset.c:
	Moved here from ecc/kernel/current/src/common, as they should
	be present even if the kernel is disabled

	* include/pkgconf/infra.h:
	Add new config options CYGIMP_INFRA_PREFER_SMALL_TO_FAST_MEMCPY
	and CYGIMP_INFRA_PREFER_SMALL_TO_FAST_MEMSET to support the
	functionality available in memcpy.c and memset.c

	* src/PKGconf.mak:
	build above new files

	Above changes are required for PR 17229

1998-10-14  Nick Garnett  <[e-mail]>

	* include/cyg_type.h:
	Moved CYG_LABEL_NAME() macro here from ktypes.h.

Wed Oct 14 17:10:12 1998  Jonathan Larmour  <[e-mail]>

	* src/diag.c: 
	Change warning message from previous change to match compiler
	output exactly

Tue Oct 13 17:23:37 1998  Jonathan Larmour  <[e-mail]>
	
	* src/diag.c: 
	Output another warning so that people know that diag.c produces
	a warning
	Reformat to 76 columns
	Change args of diag_printf to be ANSI-style, not K&R to
	silence warning

1998-09-25  Bart Veer  <[e-mail]>

	* src/null.cxx:
	PR 17471: null.cxx relies on the macro CYG_LABEL_NAME(), which on
	the mn10300 is defined only if <cyg/kernel/ktypes.h> is included.
	As a temporary fix this header file is now always included. In the
	medium term there will have to be proper fixes to ktypes.h and to
	cyg_type.h 

Wed Sep 16 03:42:16 1998  Jonathan Larmour  <[e-mail]>

	* src/startup.cxx, src/dummyxxmain.cxx: 
	Move __main() to a separate dummyxxmain.cxx source file to resolve
	linking bogosities on some targets
	Fix for PR 17279 - kudos to Tim Goodwin really

	* src/PKGconf.mak:
	Build src/dummyxxmain.cxx

Tue Sep 15 19:14:33 1998  David Moore  <[e-mail]>

	* include/pkgconf/infra.h: Cleaned up comments.

Tue Sep 15 14:34:34 1998  David Moore  <[e-mail]>

	* src/startup.cxx: 
	* include/cyg_type.h: 
	CYGBLD_ATTRIB_WEAK moved from src/startup.cxx to
 	include/cyg_type.h

Tue Sep 15 12:26:36 1998  Jonathan Larmour  <[e-mail]>

	* src/null.cxx, src/simple.cxx, src/fancy.cxx:
 	Change cyg_check_data_ptr() to not compare with _end symbol from
	linker scripts as this is a bogus thing to do when starting in
	ROM. Some better magic can be done later with the memory layout
	tool.

	* src/simple.cxx (cyg_assert_fail),
	  src/fancy.cxx (cyg_assert_fail): 
	If an assert is thrown, loop forever no matter what the platform
	rather than resetting the jmr board.

Fri Sep 11 12:52:59 1998  Hugo Tyson  <[e-mail]>

	* src/tcdiag.cxx: 
	* src/diag.c: 
	Remove dependencies on the kernel:
	 o types are available from here, infra.
	 o Diag and its mates are here and the HAL.
	
Thu Sep 10 21:59:09 1998  Hugo Tyson  <[e-mail]>

	* src/fancy.cxx: 
	* src/simple.cxx: 
	* src/null.cxx: 
	Remove dependencies on the kernel:
 	 o interrupt stuff is available	from the HAL.
	 o types are available from here, infra.
	 o Diag and its mates are here and the HAL.
	 o Only consider printing thread information if there is a kernel.
	
Thu Sep 10 21:29:55 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/infra.h: 
	Fix CDL descriptions (mainly) resulting from review of
	configury here.

Thu Sep 10 17:38:00 1998  Hugo Tyson  <[e-mail]>

	* src/null.cxx: 
	Add an empty cyg_assert_fail() if not CYGDBG_USE_ASSERTS, so that
 	clib's assert() can use it, in common with but regardless of the
	internal assert setup.  Of course if internal asserts are used,
	the same routine is used.

Thu Sep  3 19:05:29 1998  Hugo Tyson  <[e-mail]>

	* src/startup.cxx (__main): 
	...and its mates.  Correct the bad usage of the tracing macros - a
	type was implied when the type was void, so an assert fires.

	* include/diag.h (diag_printf): 
	Remove 'useful' prototype; this function deliberately has a K&R
	prototype to avoid having to use varargs, or pad arglists or
	anything grody like that.  Comment to that effect added too.
	
	* src/fancy.cxx: 
	Condition out routines which are only used by tracing system;
	prevent warnings.  Also changed the default widths setup to
	something more suitable to our long function names; viewing on
	about a 200 column screen recommended - or use 'simple' instead.

Tue Sep  1 19:09:39 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/infra.h: 
	Fancy tracing by default, as I've been requested.
	Move definition (or not) of CYGDBG_INFRA_DIAG_USE_DEVICE from the
	kernel, correcting the symbol construction as we go.

	* include/cyg_type.h: 
	Correct multiple-inclusion protection, remove
	<dollar>Version<Dollar> nonsense, correct Usage: field, put in
	definition of CYGBLD_NORET.

	* include/cyg_ass.h: 
	Correct Usage: field, remove definition of CYGDBG_NORET, correct
 	definition of cyg_assert_fail to use CYGBLD_NORET as intended.

	* include/cyg_trac.h: 
	Tidy up comments.

	* src/PKGconf.mak (COMPILE): 
	Added all the new units below.

	* src/fancy.cxx: 
	* src/simple.cxx: 
	* src/null.cxx: 
	Moved here from the kernel; comments changed accordingly.

	* src/tcdiag.cxx: 
	* include/diag.h: 
	* src/diag.c: 
	Moved here from the kernel; comments changed accordingly.
	Also use config symbol CYGDBG_INFRA_DIAG_USE_DEVICE rather than
	(badly named) CYG_DIAG_USE_DEVICE.

Fri Aug 28 15:22:16 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/infra.h: 
	Add lots of lovely cdl comments and new, correct, names for the
	config options themselves.
	* include/cyg_trac.h: 
	* include/cyg_ass.h: 
	Use the newly named options.

	[KERNEL] see also changes to src/trace/{fancy,null,simple}.cxx
	which should soon move into this package instead.

Fri Aug 28 09:57:21 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/infra.h:
	Add CYGSEM_START_ISO_C_COMPATIBILITY and
	CYGSEM_START_UITRON_COMPATIBILITY options, along with some comment.

	* src/PKGconf.mak, src/startup.cxx:
	Add these two files for the new file startup.cxx that provides the
	generic startup mechanism, using new cyg_start() functions. This
	is to remove the dependency on main(), which is defined in ISO and
	POSIX as having certain properties we wouldn't be able to give it
	otherwise.

Tue Aug 25 11:47:58 1998  Jonathan Larmour  <[e-mail]>

	* src/startup.cxx: 
	Add this to provide new startup method

1998-08-20  Nick Garnett  <[e-mail]>

	* include/cyg_type.h:
	Moved constructor priority ordering stuff here from
	kernel/ktypes.h.
