Made some more progress in removing duplicate assembly opcode files.
More improvements to how mipsread and to a lesser extent dbxread work.
See the ChangeLog for details.
stub methods. These changes are not complete in that a better
implementation will be more maintainable, but they make it possible to
debug groff with GDB.
* utils.c: All the v*fprintf emulation is now in libiberty,
so we can get rid of some junk.
* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
* m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
type operands, as used by branch instructions.
* gmalloc.c: Fix prototype of memcpy.
* elfread.c: Comment out register_addr, since it conflicts
with the one in coredep.c.
* buildsym.h: Remove extern declarations of two functions
that are really static in buildsym.c.
* tm-mips.h: Add symbolic names for more registers.
* mips-xdep.c (store_inferior_registers): Use new register names.
* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
only used for core files, not ptrace. Therefore,
the KERNEL_U_ADDR hack is no longer needed.
The mapping to ptrace number is now in in mips-xdep.c.
* mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
mapping from the old REGISTER_U_ADDR), and use it
in {fetch,store}_inferior_registers.
* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
Save/restore FP regs correctly (?).
* dbxread.c: Remove duplicate define_symbol and type_synonym_name
(these had been previously moved to buildsym.c).
Hence, define_symbol becomes extern instead of static.
* buildsym.c (read_struct_type): Comment out bogus handling
of C++ operator methods. Minor hacking of reading of class
contexts. Make define_symbol non-static, so dbxread.c can call it.
(record_line): Record directly in a subfile. Alloc on demand.
(compare_line_numbers): Add from xcoffread.c.
(end_symtab): New params say whether to sort pendings and
linetable. Patch block stabs if defined. Shrink linetable before
allocating the symtab.
* buildsym.h: Delete line_vector* and prev_line_number. Add
global_stabs and file_stabs for xcoffread.
* dbxread.c (start_subfile): Move to buildsym. Change above calls.
* symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
* symmisc.c, symtab.c: Cope with null LINETABLEs.
