+
+Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
+
+	* procfs.c: Substantial (but incomplete) changes to support
+	sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
+	struct now has substructs like struct flt_ctl instead of
+	just a fltset_t and has a ctl_fd, status_fd, as_fd, and
+	map_fd instead of a single fd.  Non-sysv4.2mp procfs models
+	still have the structs and multiple fds, but don't use the
+	entire struct and the four fds all point to the same thing.
+	We use PROCFS_USE_READ_WRITE to decide whether to talk to
+	procfs with reads/writes or use ioctl instead.  We use
+	HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
+	multiple fds or not.  PROC_NAME_FMT is split out into
+	CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT, 
+	STATUS_PROC_NAME_FMT.
+	
+	(procfs_notice_signals): now a necessary wrapper around
+	(notice_signals): which are the new guts for noticing signals
+	(open_proc_file): gets a new flag arg used in sysv4.2mp to
+	determine whether or not to attempt to open the ctl_fd.
+	(procfs_read_status): new local function, reads procfs status
+	(procfs_write_pcwstop): new local function, writes a PCWSTOP
+	(procfs_write_pckill): new local function, writes a PCKILL
+	(unconditionally_kill_inferior): remove signo since we now
+	just call procfs_write_pckill().
+	(procfs_xfer_memory): call lseek with SEEK_SET rather than 0	
+	(proc_iterate_over_mappings): the whole function is ifdefed
+	on UNIXWARE to keep things readable.
+	
+	Expanded the syscall_table to include new potential sysv4.2mp
+	members.  Note that all ifdefs of UNIXWARE should be eliminated
+	if possible or renamed to describe what's being selected for a
+	bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
+	IRIX specific code now also checks it's not UNIXWARE.
+
+	* config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
+	HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
+	* config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
+	"/debug/%d" as PROC_NAME_FMT used to be
+

+Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
+
+	* config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
+	remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
+	lousy out-of-date clone of remote.c.
+
+Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
+
+	* remote.c:  Fix problems realized while showering.
+	* (hexnumlen):  Add prototype.  Use max, not min.

+	address.
+	* (remote_ops extended_remote_ops remote_desc remote_write_size):

+	for hosts which default to unsigned chars (such as SGI's).
+	* (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
+	handled automatically in remote.c.
+
+Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
+
+	* blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), 
+	find_pc_sect_function(), find_pc_sect_partial_function(): new 
+	functions for debugging overlays; pc without section is ambiguous.
+	* breakpoint.[ch]: add section pointer to breakpoint struct;
+	add section argument to check_duplicates(); check section as well
+	as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
+	breakpoint_thread_match(), bpstat_stop_status()];  
+	add section argument to describe_other_breakpoints(); 
+	use INIT_SAL() macro to zero-out new sal structures; 
+	make resolve_sal_pc() fix up the sal's section as well as its pc; 
+	match on section + pc in clear_command() and delete_breakpoint(); 
+	account for overlay sections in insert_breakpoints(), 
+	remove_breakpoint() and breakpoint_re_set_one();
+	all this to support overlays where a PC is not unique.
+	* exec.c: change xfer_memory() to handle overlay sections.
+	* findvar.c: change read_var_value() to handle overlay sections.
+	* frame.h: declaration for block_for_pc_sect() [blockframe.c].

+	that's not in memory.  Also use INIT_SAL() to initialize sals.
+	* infrun.c: wait_for_inferior() sets a flag to invalidate cached
+	overlay state information; Also use INIT_SAL() to init sals.
+	* m32r-rom.c: modify load routines to use LMA instead of VMA.
+	* m32r-stub.c: mask exit value down to 8 bits; screen out any
+	memory read/writes in the range 600000 to a00000, and ff680000
+	to ff800000 (hangs because nothing is mapped there); fix strcpy().
+	* maint.c: maintenance command "translate-address" supports overlays.
+	* minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
+	* objfiles.[ch]: add ovly_mapped field to the obj_section struct;
+	this constitutes gdb's internal overlay mapping table.  Add macro
+	ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
+	Add function find_pc_sect_section().
+	* printcmd.c: modify print_address_symbolic() with overlay smarts;
+	modify address_info() with overlay smarts; add function sym_info() 
+	to support the INFO SYMBOL command (translate address to symbol(s));
+	modify disassemble_command() to work on unmapped overlays.
+	* source.c: use INIT_SAL() to initialize sals.
+	* symfile.[ch]: change generic_load() to use section's LMA address
+	instead of VMA address, for overlay sections.
+	Add numerous functions for finding a PC's section / overlay, 
+	translating between VMA and LMA address ranges, determining if an
+	overlay section is mapped, etc.  Add several user commands for
+	overlay debugging.  Add support for a "generic" form of automatically
+	reading overlay mapping info from the inferior (based on the default
+	(simple) overlay manager which Cygnus provides as an example).
+	* symtab.[ch]: add functions find_pc_sect_symtab(), 
+	find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
+	for lookup; modify lookup_symbol and decode_line_1() to use them;
+	modify find_function_start_sal() to account for overlay sections;
+	add macro INIT_SAL() for initializing struct symtab_and_line.
+	* target.c: fix a comment in the declaration of target_ops.

+	* mn10300-tdep.c (mn10300_push_arguments): rewrote,

+	* config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
+	ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
+	arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
+	EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
