<PREFERRED_DEBUGGING_TYPE>: Changed to DWARF2_DEBUG.
<PUT_SDB_DEF>: Deleted.
* config/or32/or32.h: Obsolete code surrounded by "#if 0" removed
for clarity.
<SDB_DELIM>: Definition deleted.
<DBX_CONTIN_LENGTH, DBX_CONTIN_CHAR, DBX_REGISTER_NUMBER>:
Definition deleted (default suffices).
<DWARF2_UNWIND_INFO, DWARF2_FRAME_INFO>: Defined.
<DWARF2_ASM_LINE_DEBUG_INFO, INCOMIN_RETURN_ADDR_RTX>: Defined.

246 ORPmon update - compatiable with new GCC, added new spr-defs file, better tboot reliability julius 5185d 22h /
245 Fixed minor glitch in build script. Corrected newlib options and added GDB options for simulator script. Updated README to refer to IRC channel. jeremybennett 5189d 06h /
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 5189d 06h /
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 5189d 06h /
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 5189d 06h /
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 5189d 06h /
240 or1ksim build fixups for Cygwin copilation julius 5201d 07h /
239 or1ksim fixed SPR_VR_RESV value julius 5203d 03h /

236 Terminate execution on NOP_EXIT, even if debugging, add support for RSP qAttached packet, stall in library after single instruction is ST bit is set in SPR DMR1. Fix softfloat to allow compilation with -O0 for debugging.

* configure: Regenerated.
* configure.ac: Version changed to current date. Test for
varargs.h dropped.
* cpu/or32/insnset.c <l_nop>: Terminate execution on NOP_EXIT,
even if debugging.
* debug/rsp-server.c (rsp_query): Added support for qAttached
packet.
* libtoplevel.c (or1ksim_run): Stall after a single instruction if
SPR_DMR1_ST flag is set.
