+Tue Jun 6 10:44:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
+
+ From Andrew Cagney <cagney@highland.com.au>
+ * rs6000-tdep.c (single_step): Handle both little and big endian
+ breakpoints.
+ (gdb_print_insn_powerpc): Deal with disassembling both little and
+ big endian PowerPC systems.
+ (_initialize_rs6000_tdep): Use gdb_print_insn_powerpc to handle
+ disassembly, rather that assuming big endian order.
+
+ * config/rs6000/tm-rs6000.h (BREAKPOINT): Delete.
+ (BIG_BREAKPOINT): Define, big endian breakpoint instruction.
+ (LITTLE_BREAKPOINT): Define, little endian breakpoint instruction.
+
+Sat Jun 3 01:54:56 1995 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
+
+ * README: Add note about Unixware 2.x.
+
+ * dbxread.c (process_one_symbol): Check for exact symbol name
+ match when fixing up N_GSYM and N_STSYM symbols from Sun acc.
+
+ * valprint.c (value_print_array_elements): Use
+ fprintf_filtered to put out `<repeats %u times>',
+ from schwab@issan.informatik.uni-dortmund.de (Andreas Schwab).
+
+ * value.h (struct value): Change `repetitions' field from
+ `short' to `int' type.
