+ * dink32-rom.c: New file, support for DINK32 monitor.
+ * Makefile.in (dink32-rom.o): Add build rule.
+ * config/powerpc/ppc-eabi.mt, config/powerpc/ppc-sim.mt
+ (TDEPFILES): Add dink32-rom.o.
+ * monitor.h (MO_32_REGS_PAIRED, MO_SETREG_INTERACTIVE,
+ MO_SETMEM_INTERACTIVE, MO_GETMEM_16_BOUNDARY,
+ MO_CLR_BREAK_1_BASED): New monitor interface flags.
+ * monitor.c: Use them.
+ (monitor_store_register): Use setreg.term if defined.
+ (monitor_insert_breakpoint, monitor_remove_breakpoint): Notice

- * ocd.c (ocd_insert_breakpoint, ocd_remove_breakpoint): macro
+ * ocd.c (ocd_insert_breakpoint, ocd_remove_breakpoint): Macro
BDM_BREAKPOINT already has braces around it, remove erroneous ones.
- * ser-ocd.c (ocd_write): conditionalize on _WIN32 instead of
- __CYGWIN32__
- * config/powerpc/tm-ppc-eabi.h: remove BDM_NUM_REGS, BDM_REGMAP
+ * ser-ocd.c (ocd_write): Conditionalize on _WIN32 instead of

+ * config/powerpc/tm-ppc-eabi.h: Remove BDM_NUM_REGS, BDM_REGMAP
* ppc-bdm.c: move BDM_NUM_REGS, BDM_REGMAP here from tm.h file,
fill in doc fields of bdm_ppc_ops.
- (bdm_ppc_fetch_registers): don't ask for invalid registers such
- as the MQ or floating point regs not present on ppc 8xx boards
- (bdm_ppc_store_registers): don't write those same invalid registers
- * config/i386/cygwin32.mh: stop including ocd.o ser-ocd.o
