244 Don't try to skip prologue using SAL info (fails with STABS). Fuller check of prologue. Change register names to rnn from gprnn to match assembler. Add debug option to simulator wrapper.

* or32-tdep.c (or32_register_name): Changed to rnn rather than
gprnn to mach the assembler.
(or32_is_arg_reg, or32_is_callee_saved_reg): Added.
(or32_skip_prologue): Don't use skip_prologue_using_sal. Check for
argument as well as callee saved registers in prologue.
(or32_frame_cache):Check for argument as well as callee saved
registers in prologue.

* wrapper.c: OR32_SIM_DEBUG added to control debug messages.
(sim_close, sim_load, sim_create_inferior, sim_fetch_register)
(sim_stop): Debug statement added.
(sim_read, sim_write): Debug statements now controlled by
OR32_SIM_DEBUG.
(sim_store_register, sim_resume): Debug statement added and
existing debug statements now controlled by OR32_SIM_DEBUG.		 jeremybennett 5103d 06h /openrisc/trunk/gnu-src/
243 Fixed libgloss for compiled code with leading underscores removed.

* libgloss/or32/crt0.S (_start): Remove all leading underscores from
references to global C functions and variables (printf, stack,
atexit, _uart_init, main). Modified end of memory detection, so it
works on rentry as well as initial entry. <buserr>: New code to
allow re-entrant _start function.		 jeremybennett 5103d 06h /openrisc/trunk/gnu-src/
242 Generate global symbols without leading underscore. Tidy up generation of .proc directive.

* config/or32/elf.h <PUT_SDB_DEF>: Definition removed.
<USER_LABEL_PREFIX>: Modified to match or32.h
* config/or32/linux-elf.h<USER_LABEL_PREFIX>: Modified to match
or32.h
* config/or32/or32.h <LIB_SPEC>: Changed to use free instead of
_free to match change in USER_LABEL_PREFIX.
<USER_LABEL_PREFIX>: Changed from "_" to "".
<ASM_OUTPUT_FUNCTION_PREFIX>: Surround .proc by tab chars.
* config/or32/or32.S (__mulsi3, __udivsi3, __divsi3, __umodsi3)
(__modsi3): Changed from ___mulsi3, ___udivsi3, ___divsi3,
___umodsi3 and ___modsi3 respectively to match change in
USER_LABEL_PREFIX.		 jeremybennett 5103d 06h /openrisc/trunk/gnu-src/
241 Ensure register and symbol operands are never confused.

* gas/config/tc-or32.c (parse_operand): New argument to specify that
operand is a register.
(machine_ip): All uses of parse_operand updated to use new argument.		 jeremybennett 5103d 06h /openrisc/trunk/gnu-src/
