numbering changes in include/coff/mips.h. Add entries for
MIPS_R_RELHI and MIPS_R_RELLO.
(mips_ecoff_swap_reloc_in): Handle an extra bit for the reloc type
when little endian. Treat internal MIPS_R_RELLO or MIPS_R_RELHI
relocs like MIPS_R_SWITCH, and convert r_offset from 24 to 32
bits.

reflo_int_rel to lo_int_rel. Handle MIPS_R_RELLO and MIPS_R_RELHI
relocs.

* binutils.all/objdump.exp: Add more wildcards to list of
single-letter options in pattern for usage message.
* binutils.all/nm.exp: Deleted debug-symbols test, since it only
works for a.out/stabs systems. Fixed regexps to make underscores
optional, since some C compilers don't prepend them. Deleted
check for foo.o symbol, since again some systems don't generate
it.
bp_watchpoint_scope breakpoints.
(struct breakpoint): Add val_chain and related_breakpoint fields
for use by watchpoints.

makes all local watchpoints go out of scope).
(bpstat_stop_status): Handle hardware watchpoints much like normal
watchpoints. Delete the watchpoint and watchpoint scope breakpoint
when the watchpoint goes out of scope. Remove and reinsert all
breakpoints before returning if we stopped when a hardware watchpoint
fired.

watching a local expression, build a scope breakpoint too.
(map_breakpoint_numbers): Also call given function for any
related breakpoints.
(disable_breakpoint): Never disable a scope breakpoint.

watchpoints. When necessary handle watchpoint_scope breakpoints.

order.
(subseg_get): Clear newly allocated seginfo, set its pointer slots
to NULL instead of 0.
Fixes a problem observed in sparc-lynx progressive.
* xcoffread.c (read_xcoff_symtab): Ignore symbols of class C_EXT,
smtyp XTY_LD, sclass XMC_DS (external data segment label). They
often have the same names as debug symbols for functions, and
confuse lookup_symbol().
* config/pa/tm-hppa.h (REGISTER_BYTES): Use 4 rather than
REGISTER_RAW_SIZE (1).
Together these changes work around a bug in HP's compiler. Both
seem to be necessary.
.fini sections into .text; keep them separate.
* config/i386sco.mh (HOSTING_CRT0): If ../gcc/crtbegin.o does not
exist, get crtbegin based on gcc -print-libgcc-file-name.
(HOSTING_LIBS): Similar change for ../gcc/crtend.o.

stops in mid-line in the caller. Add xfail for returning a float
value on X86 targets.
(NAME(aout,some_aout_object_p)): Call NAME(aout,make_sections)
rather than making sections inline.
(NAME(aout,mkobject)): Don't make any sections.
(NAME(aout,adjust_sizes_and_vmas)): Call NAME(aout,make_sections).
(NAME(aout,final_link)): Don't dereference obj_textsec (abfd) or
obj_datasec (abfd) if they are NULL.

Handle stStatic and stStaticProc symbols in stabs-in-ecoff output
by entering them into the minimal symbol table.
* printcmd.c (print_scalar_formatted): Do not try to unpack to
a long for float formats.
* solib.c: Include "elf/mips.h" only if DT_MIPS_RLD_MAP does not
get defined in <link.h>.

table of the target before adding the symbols.
* partial-stab.h: Relocate static and global functions.

end_of_text_address. Relocate text_addr when passing it

symbols from stripped executables.
