* 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:

* 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.

* 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.
