Tue Mar 7 00:23:47 1995 Stu Grossman (grossman@cygnus.com)
+ * Makefile.in: Add rules for monitor.o and rom68k-rom.o to make
+ Sun make (with VPATH) work...
+
+ * monitor.c monitor.h rom68k-rom.c: Serious cleanup to make IDP
+ (rom68k) target work right.
+ * array-rom.c op50-rom.c w89k-rom.c: Partial updates to new
+ monitor.c interface. More work needs to be done here.
+ * config/m68k/tm-monitor.h: Change DECR_PC_AFTER_BREAK to 0 to
+ match the IDP monitor. Also, set NUM_REGS to 18 cuz there's no
+ floating-point for this card.
+
* serial.h ser-go32.c ser-go32-para.c ser-mac.c ser-tcp.c
ser-unix.c: Add SERIAL_SETSTOPBITS to set the number of stopbits
(needed for IDP board?!?!?).
