1333 gcc 3.4 compile fix phoenix 7301d 12h /or1k/trunk/insight/gdb/or1k-tdep.c
1144 Speed up gdb when running with serial targets:

When generating backtraces, the prologue of each function is scanned
at least three times by architecture-independent code, e.g. to
determine offsets of saved registers, identify frameless functions,
etc. This new code adds straightforward caching of the information
gleaned by or1k_scan_prologue() on a per-frame basis rather than
storing it in global static variables. (This benefits both JTAG and
serial gdb targets, though the JTAG target runs fast enough that it is
not particularly needed.)

When the register set is dumped by the serial target, e.g. at any
breakpoint or interrupt, the 32 vector/FP registers were included in
the dump (each 8 bytes long), though they aren't implemented. The new
code tells gdb that unimplemented registers have zero length in the
dump.

1115 Fix stack-walking code in or1k_frame_chain() and or1k_skip_prologue()
to expect the function prologue that or32 gcc currently emits, rather
than a previous incarnation of the or1k ABI.

362 some changes based on current modifications to or1k; cleaner register naming; ctrl-c causes stepi; write&read pc work on next instruction markom 8433d 18h /or1k/trunk/insight/gdb/or1k-tdep.c
207 Several major changes to allow gdb to work with an Or1k implementation
that does not need a writeable PC. This version will use the breakpoint
vector and install a new vector into the EPC register, and then single
step out of the breakpoint exception. The breakpoint exception vector
must include only 2 commands: l.rfe and l.nop. Anything else and this
gdb version will fail w/ or1ksim.
