address.

limit size of memory read and write commands.

another target switch to the remote target.
* target.h: Add prototype for push_remote_target.
* sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
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.
* gdb.base/help.exp: update help msg for INFO ADDR; add help test
for INFO SYMBOL; add help tests for OVERLAY commands.
* gdb.base/default.exp: add tests for INFO SYMBOL command;
add tests for OVERLAY commands

* gdb.base/sigall.c: add usestubs code frag
* gdb.base/watchpoint.c: turn on complex watchpoint test for M32R.
Except for the two m32r modules, this checkin is for
overlay support.
* 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].
* infcmd.c: jump_command() warns against jumping into an overlay
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.

with MIPS16 call/return thunks.

INIT_FRAME_PC_FIRST macro; includes code from old macro plus

(mips_frame_chain): Skip over MIPS16 thunks.
* config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
mips_skip_stub, mips_ignore_helper): Declare.

to decide if certain library function calls should be ignored.
or netport.
* lib/gdb.exp: Set GDB to [transform gdb] if we're using a remote host
and it's not already set.
* gdb.base/setshow.exp: Only test the run command if the target
isn't using a stub and if it supports argument passing.
* symtab.c (find_pc_symtab): change to support the case
where the objfile is reordered and contains both coff and
stabs debugging info (continue on if a psymtab isn't found).
* gdb.disasm/mn10300.exp: Run mn10300 disassembler tests.
* gdb.disasm/Makefile.in: Remove "mn10300" when cleaning.
disassembler testsuite for the mn10300.
* config/mips/tm-mips.h (REGISTER_CONVERT_TO_TYPE,
REGISTER_CONVERT_FROM_TYPE): Swap words if target, not host,
is big-endian and if registers are 32 bits.
* mips-tdep.c (mips_print_register, mips_extract_return_value,
mips_store_return_value): Fix floating-point word-order problems on
little-endian targets introduced by changes of Mar 21.

traces.
(display_trace): Find and display source line if requested.

little-endian hosts.
(mips_extract_return_value): Return double values correctly
on little-endian hosts.
* mdebugread.c (parse_procedure): Adjust address of procedure relative
to address in file descriptor record; this accounts for constant
strings that may precede functions in the text section. Remove
now-useless lowest_pdr_addr from argument list and all calls.
