2002-11-01 Joel Sherrill <joel@OARcorp.com>
* mips-stub.c: Removed warnings.
2002-10-02 Joel Sherrill <joel@OARcorp.com>
* rtems-stub-glue.c: Removed should only be common copy.
2002-08-14 Greg Menke <gregory.menke@gsfc.nasa.gov>
* mips-stub.c: Re-debugged a breakpoint problem, zbreak target
address was a char * which caused the target instruction to not
be fully copied, so the zbreak logic corrupted the original
instruction and didn't insert a valid break instruction.
2002-03-08 Joel Sherrill <joel@OARcorp.com>
* mips-stub.c: Removed warnings.
2002-03-05 Greg Menke <gregory.menke@gsfc.nasa.gov>
* mips-stub.c: Debugged & tweaked the gdb command processing,
zbreak stuff, breakpoint and step code. Implemented 'T' command
support and debugged remote gdb support w/ the Mongoose bsp.
Added the memory segment support.
* memlimits.h: Disabled all contents in favor of memory sement
support. This file could probably go away.
* rtems-stub-glue.c (rtems_gdb_index_to_stub_id()): New routine.
rtems_gdb_stub_get_register_from_context(): Implemented MIPS version.
rtems_gdb_stub_get_offsets(): Implemented MIPS version.
* README: Updated.
2002-03-01 Joel Sherrill <joel@OARcorp.com>
* ChangeLog: Corrected previous entry.
2002-02-27 Greg Menke <gregory.menke@gsfc.nasa.gov>
* mips-stub.c: Modified isr install routine to
capture all exceptions.
2001-02-27 Joel Sherrill <joel@OARcorp.com>
* Significant modifications including adding thread support, the 'X'
command, and reorganizing so that target CPU independent routines
could be reused.
* gdb_if.h: Added numerous prototypes.
* mips-stub.c: Added thread support as well as 'X' command.
Also noticed that the 'P' command was from the mips protocol.
* rtems-stub-glue.c: New file. This file contains all generic
support which should be able to be reused on another target CPU.
2002-02-08 Joel Sherrill <joel@OARcorp.com>
* mips-stub.c (handle_exception): Prototype changed to be an RTEMS
entry point. Added comments about possible need to flush cache.
(mips_gdb_stub_install): New routine.
2002-02-08 Joel Sherrill <joel@OARcorp.com>
* Makefile, stubinit.S, r46kstub.ld, ioaddr.h: Removed as unused
with RTEMS.
* r46kstub.c: Renamed to mips-stub.c.
* mips-stub.c: New file -- was r46kstub.c.
* memlimits.h: New file was limits.h.
* limits.h: Removed.
* r4600.h: Eliminated need for this file.
* README: Updated.
* gdb_if.h: Added CVS Id.
* mips-stub.c: Attempt to deal with MIPS1 versus MIPS3.
2002-02-08 Joel Sherrill <joel@OARcorp.com>
* Merged r46kstub.c into RTEMS distribution without modification.
I got the code from Franz Fischer <Franz.Fischer@franz-fischer.de>
who had used this with an old version of RTEMS with the mips64orion
port of RTEMS. After adding this to the repository, I will tailor
this to work with the RTEMS exception processing model and trim
no longer needed parts.
* ChangeLog, gdb_if.h, ioaddr.h, limits.h, Makefile, mips_opcode.h,
r4600.h, r46kstub.c, r46kstub.ld, README, stubinit.S:
Sun Sep 29 16:34:53 1996 C. M. Heard <heard@vvnet.com>
* Updated snapshot posted.
* stubinit.S (_reset_exception, _general_exception): Reorder
instructions or insert nops as necessary to ensure that the
target register of mfc0, mfc1, and cfc1 instructions is not
used as a source register in the load delay slot of those
instructions and to ensure that the instruction following
mtc0 is always something other than mfc0. Insert .eject
directives and reformat some of the comments to make the
assembler listing more readable.
* ioaddr.h: add comments pointing out implementation-
specific address definitions.
* limits.h: add comments describing what the implementation-
specific macros in this file are supposed to do.
Tue Aug 06 14:43:04 1995 C. M. Heard <heard@vvnet.com>
* Updated snapshot posted.
* stubinit.S (_general_exception): Use virtual adresses from
kseg0 (cached, unmapped space) instead of kseg1 (uncached,
unmapped space) in cache instructions.
(_reset_exception): Likewise, and use the right
mask to clean the K0 field in the config register.
Fri Jul 26 14:41:49 1995 C. M. Heard <heard@vvnet.com>
* Initial snapshot posted.
