|---|
| 3 | * mips-stub.c: Re-debugged a breakpoint problem, zbreak target |
|---|
| 4 | address was a char * which caused the target instruction to not |
|---|
| 5 | be fully copied, so the zbreak logic corrupted the original |
|---|
| 6 | instruction and didn't insert a valid break instruction. |
|---|

|---|
| 10 | * mips-stub.c: Removed warnings. |

| 12 | 2002-03-05 Greg Menke <gregory.menke@gsfc.nasa.gov> |
|---|
| 13 | |
|---|
| 14 | * mips-stub.c: Debugged & tweaked the gdb command processing, |
|---|
| 15 | zbreak stuff, breakpoint and step code. Implemented 'T' command |
|---|
| 16 | support and debugged remote gdb support w/ the Mongoose bsp. |
|---|
| 17 | Added the memory segment support. |
|---|
| 18 | * memlimits.h: Disabled all contents in favor of memory sement |
|---|
| 19 | support. This file could probably go away. |
|---|
| 20 | * rtems-stub-glue.c (rtems_gdb_index_to_stub_id()): New routine. |
|---|
| 21 | rtems_gdb_stub_get_register_from_context(): Implemented MIPS version. |
|---|
| 22 | rtems_gdb_stub_get_offsets(): Implemented MIPS version. |
|---|
| 23 | * README: Updated. |

| 29 | 2002-02-27 Greg Menke <gregory.menke@gsfc.nasa.gov> |
|---|
| 30 | |
|---|
| 31 | * mips-stub.c: Modified isr install routine to |
|---|
| 32 | capture all exceptions. |
|---|
| 33 | |
|---|
| 34 | 2001-02-27 Joel Sherrill <joel@OARcorp.com> |
|---|
| 35 | |
|---|
| 36 | * Significant modifications including adding thread support, the 'X' |
|---|
| 37 | command, and reorganizing so that target CPU independent routines |
|---|
| 38 | could be reused. |
|---|
| 39 | * gdb_if.h: Added numerous prototypes. |
|---|
| 40 | * mips-stub.c: Added thread support as well as 'X' command. |
|---|
| 41 | Also noticed that the 'P' command was from the mips protocol. |
|---|
| 42 | * rtems-stub-glue.c: New file. This file contains all generic |
|---|
| 43 | support which should be able to be reused on another target CPU. |
|---|
| 44 | |
|---|
| 45 | 2002-02-08 Joel Sherrill <joel@OARcorp.com> |
|---|
| 46 | |
|---|
| 47 | * mips-stub.c (handle_exception): Prototype changed to be an RTEMS |
|---|
| 48 | entry point. Added comments about possible need to flush cache. |
|---|
| 49 | (mips_gdb_stub_install): New routine. |
|---|
| 50 | |
|---|
| 51 | 2002-02-08 Joel Sherrill <joel@OARcorp.com> |
|---|
| 52 | |
|---|
| 53 | * Makefile, stubinit.S, r46kstub.ld, ioaddr.h: Removed as unused |
|---|
| 54 | with RTEMS. |
|---|
| 55 | * r46kstub.c: Renamed to mips-stub.c. |
|---|
| 56 | * mips-stub.c: New file -- was r46kstub.c. |
|---|
| 57 | * memlimits.h: New file was limits.h. |
|---|
| 58 | * limits.h: Removed. |
|---|
| 59 | * r4600.h: Eliminated need for this file. |
|---|
| 60 | * README: Updated. |
|---|
| 61 | * gdb_if.h: Added CVS Id. |
|---|
| 62 | * mips-stub.c: Attempt to deal with MIPS1 versus MIPS3. |
|---|
| 63 | |
|---|
| 64 | 2002-02-08 Joel Sherrill <joel@OARcorp.com> |
|---|
| 65 | |
|---|
| 66 | * Merged r46kstub.c into RTEMS distribution without modification. |
|---|
| 67 | I got the code from Franz Fischer <Franz.Fischer@franz-fischer.de> |
|---|
| 68 | who had used this with an old version of RTEMS with the mips64orion |
|---|
| 69 | port of RTEMS. After adding this to the repository, I will tailor |
|---|
| 70 | this to work with the RTEMS exception processing model and trim |
|---|
| 71 | no longer needed parts. |
|---|
| 72 | * ChangeLog, gdb_if.h, ioaddr.h, limits.h, Makefile, mips_opcode.h, |
|---|
| 73 | r4600.h, r46kstub.c, r46kstub.ld, README, stubinit.S: |

|---|
| 76 | |
|---|
| 77 | * Updated snapshot posted. |
|---|
| 78 | |
|---|
| 79 | * stubinit.S (_reset_exception, _general_exception): Reorder |
|---|
| 80 | instructions or insert nops as necessary to ensure that the |
|---|
| 81 | target register of mfc0, mfc1, and cfc1 instructions is not |
|---|
| 82 | used as a source register in the load delay slot of those |
|---|
| 83 | instructions and to ensure that the instruction following |
|---|
| 84 | mtc0 is always something other than mfc0. Insert .eject |
|---|
| 85 | directives and reformat some of the comments to make the |
|---|
| 86 | assembler listing more readable. |
|---|
| 87 | |
|---|
| 88 | * ioaddr.h: add comments pointing out implementation- |
|---|
| 89 | specific address definitions. |
|---|
| 90 | |
|---|
| 91 | * limits.h: add comments describing what the implementation- |
|---|
| 92 | specific macros in this file are supposed to do. |
|---|
| 93 | |
|---|
| 94 | Tue Aug 06 14:43:04 1995 C. M. Heard <heard@vvnet.com> |
|---|
| 95 | |
|---|
| 96 | * Updated snapshot posted. |
|---|
| 97 | |
|---|
| 98 | * stubinit.S (_general_exception): Use virtual adresses from |
|---|
| 99 | kseg0 (cached, unmapped space) instead of kseg1 (uncached, |
|---|
| 100 | unmapped space) in cache instructions. |
|---|
| 101 | (_reset_exception): Likewise, and use the right |
|---|
| 102 | mask to clean the K0 field in the config register. |
|---|
| 103 | |
