-------------------
User-visible changes in version 1.5 (since version 1.4.1):
* New features/improvements:
* VMIPS now includes a basic direct-mapped cache simulation. The
cache isolation and cache swap bits in the CP0 Status register are
now honored.
* The boot monitor distributed with VMIPS now sets up a dummy
`argv[0]' value for the loaded program. Also, it halts by entering
an infinite loop rather than attempting to execute a `break'
instruction when it encounters an unexpected exception.
* The setup assembly routine distributed with VMIPS has been made
more TLB-friendly. Identity virtual-to-physical mappings for the
first few pages of physical RAM are installed in the TLB at program
start time.
* When `-o excmsg' is on, TLB miss addresses will be printed to
stderr.
* When `-o ttydev=stdout' is specified, simulated program output
will be sent to VMIPS's standard output, even if it is not a tty.
* The interactor can now disassemble memory. Also, stepping in the
interactor now prints the PC after each step.
* VMIPS now supports more of the GDB remote serial protocol, in
support of the GDB `info threads' and `detach' commands. The debug
protocol TCP port is now configurable via the `-o debugport'
option. Also, if something halts the program while the debugger
interface is active, VMIPS will tell GDB that the program exited.
* Bug fixes:
* A bug was fixed in the debugger interface where disconnecting from
the debugger socket could cause vmips to enter an infinite loop.
* The interactor will refuse to dump raw memory words at
non-word-aligned addresses.
* The CP0 Cause register IP field is now recomputed whenever the
register is read, rather than only when exceptions happen. This
makes polling loops with interrupts disabled work correctly.
* A bug was fixed in the DECstation-compatible clock device which was
preventing some of its registers from being zeroed properly.
* Some endianness bugs were fixed in the generic memory-mapped device
code and in the DECstation-compatible serial device.
