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.	sfurman	7745d 09h	/or1k/trunk/gdb-5.0/

1124	Initialize or1k_implementation with reasonable defaults for the number of implementation registers. This doesn't affect the jtag or sim targets at all because those values are always overwritten when or1k_implementation is initialized. However, it is necessary when connecting to remote gdb stubs through a serial port or socket, since or1k_implementation is not yet initialized for those targets.	sfurman	7779d 01h	/or1k/trunk/gdb-5.0/
1123	Renumber/rename SPRs to match latest architecture doc	sfurman	7780d 08h	/or1k/trunk/gdb-5.0/
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.	sfurman	7802d 05h	/or1k/trunk/gdb-5.0/
