+
+ From 1999-09-12 Jim Blandy <jimb@cris.red-bean.com>:
+ * gdbarch.sh (generating setters): Use sed to generate the proper
+ indentation, not tr; tr's behavior is notoriously unportable.
+
+1999-09-10 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * i387-tdep.c (print_387_control_bits): Don't print newline; the
+ callers take care of that. (Thanks to H.J. Lu.)
+
+1999-09-09 Stan Shebs <shebs@andros.cygnus.com>
+
+ * d10v-tdep.c (DMEM_START): Set to 0x2000000.
+ (itrace, iuntrace, info itrace, itdisassemble, itracedisplay,
+ itracesource): Add 'i' prefix to commands, so as not to conflict
+ with generic trace commands.
+
+1999-09-09 Fernando Nasser <fnasser@totem.to.cygnus.com>
+
+ * remote.c (_initialize_remote): Fix the specification of the
+ "remote" prefix to set and show commands.
+
+1999-09-09 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
+
+ * event-loop.c (create_file_event): New function. Creates a gdb
+ event for a given fd.
+ (gdb_wait_for_event): Use create_file_event().
+ * event-loop.h: export create_file_event().
+
+ * event-loop.c (delete_file_handler): Move the clearing of the
+ mask to later on in the function, because we need it in order to
+ deactivate the correct fd when using select().
+
+ * m32r-tdep.c (decode_prologue): Fix typo. Instructions starting
+ with 0xf are branch instructions.
+ (m32r_scan_prologue): Initialize framesize to 0.
+
1999-09-07 J.T. Conklin <jtc@redback.com>
