sim: erc32: fix linking against local readline on modern (ncurses) systems

The current erc32 configure script only searches for -ltermcap to provide
any termcap funcs (which readlines needs).  When building against a local
readline (which is static), we hit link failures like so:
  gcc ...-I/-D flags... -o sis \
    sis.o exec.o erc32.o func.o help.o float.o \
    ../../bfd/libbfd.a ../../opcodes/libopcodes.a \
    ../../libiberty/libiberty.a -lz -lnsl \
    ../../readline/libreadline.a -lm
  ../../readline/libreadline.a(display.o): In function 'cr':
  .../readline/display.c:2486: undefined reference to 'tputs'
  collect2: ld returned 1 exit status
  make[2]: *** [sis] Error 1

Use AC_SEARCH_LIBS from gdb's configure.ac as suggested by Joel Brobecker
to check for additional termcap providers.

sim: cr16: add ifdefs around undefined syscalls

The cr16 libgloss port does not define these syscall numbers, so trying
to use them results in build failures [1].  The cr16 code already uses
ifdefs around a bunch of syscalls, so extend that style to cover the
ones that are currently missing.  Now we can at least compile.

Improve gdb_realpath for Windows hosts

On Windows hosts, gdb_realpath is just an xstrdup. This makes filename
comparisons on Windows very chancy. Normally, we would normalize both
paths, and then compare.  But since the normalization doesn't do
anything, two equivalent names on Windows might not match.  This can
happen when trying to insert a breakpoint using the fullpath of a file.
For instance, if the compiler generated debug info that says that
the compilation directory is: `c:\\some\\double\\slashes\\dir', then
trying to insert a breakpoint on `c:/some/double/slashes/dir/foo.c:4'
does not work:

    (gdb) b c:/some/double/slashes/dir/foo.c:4
    No source file named c:/some/double/slashes/dir/foo.c:4.
    (gdb) b c:\some\double\slashes\dir\foo.c:4
    No source file named c:\some\double\slashes\dir\foo.c:4.

This fixes the problem by enhancing gdb_realpath on Windows hosts.
The code is inspired from libiberty's lrealpath.

        * utils.c (gdb_realpath): Add better support for Windows hosts.

Use symbol search name in expand_symtabs_matching_via_partial...

We are iterating over all symbols in a partial symtab that would
match a given name, so we should match the partial symbols
search name against the given name rather than using the natural
name.  In C++, that does not make a difference, but it does in
Ada, because Ada searches using the symbol encoded name...

We also update the generation of the .gdb_index file to match this
change in the search. Although technically an incompatible change,
we do not increment the gdb_index version number, because Ada is
the only language where it would make a difference - except that
this feature is not supported for Ada.

        * psymtab.c (expand_symtabs_matching_via_partial): Match
        the partial symbols using their SYMBOL_SEARCH_NAME.
        * symfile.h (struct quick_symbol_functions): Udate the

Add handling for unqualified Ada operators in linespecs

This patch enhances the linespec parser to recognize unqualified
operator names in linespecs. This allows the user to insert a breakpoint
on operator "+" as follow, for instance:

        (gdb) break "+"

Previously, it was possible to insert such a breakpoint, but one
had to fully qualify the function name. For instance:

        (gdb) break ops."+"

gdb/ChangeLog:

        * linespec.c (locate_first_half): Add handling of Ada operators
        when the current language is Ada.

missing check against overlay_debugging in objfiles.c

This fixes a problem where the debugger is trying to locate a minimal
symbol from its address, when the symbol is inside a section whose
VMA is different from its LMA.

We have a program that was built on ppc-elf using a linker script
such that data sections are placed in ROM, and then loaded onto RAM
at execution.  So their VMA addresses are indeed different from
their LMA address.

Unfortunately, there is one place where GDB gets slightly confused
into thinking that these data sections are overlayed, while it's
not the case here.  This show up when trying to print the list of
Ada tasks, where GDB is unable to determine their names, and thus
prints a generic `Ravenscar task' instead:

    (gdb) info tasks
       ID       TID P-ID Pri State                  Name
        1     1d580      127 Delay Sleep            Ravenscar task
        2     183f8      127 Delay Sleep            Ravenscar task
    *   3     13268      127 Runnable               Ravenscar task

We expected:

    (gdb) info tasks
       ID       TID P-ID Pri State                  Name
        1     1d580      127 Delay Sleep            environment_task
        2     183f8      127 Delay Sleep            raven2
    *   3     13268      127 Runnable               raven1

The name of the task is determined by looking up the symbol table
using the task ID, which is the address where the symbol is defined.
So, ada-tasks calls...

    msym = lookup_minimal_symbol_by_pc (task_id);

... which in turn first tries to determine the section associated
to this address (find_pc_section), which itself uses a map of sections
to find it. The map itself is recomputed every time objfiles are
loaded/changed by `update_section_map'. And `update_section_map'
relies on `insert_section_p' to determine whether the section should
be inserted in the map or not.

This is where things get interesting for us, because `insert_section_p'
simply rejects overlay sections:

  if (lma != 0 && lma != bfd_section_vma (abfd, section)
      && (bfd_get_file_flags (abfd) & BFD_IN_MEMORY) == 0)
    /* This is an overlay section.  IN_MEMORY check is needed to avoid
       discarding sections from the "system supplied DSO" (aka vdso)
       on some Linux systems (e.g. Fedora 11).  */
    return 0;

However, it shouldn't reject our section in this case, since overlay
debugging is off.  The fix is to add a check that overlay debugging
is active before rejecting the section.  This is similar to what is
done in `section_is_overlay' (which takes obj_section objects), for
instance.

gdb/Changelog:

        * objfiles.c (insert_section_p): Do not detect overlay sections
        if overlay debugging is off.

[Ada] Breakpoints on task bodies

Consider the following declaration:

    package Pck is
       task Dummy_Task is
          entry Start;
       end Dummy_Task;
    end Pck;

Inserting a breakpoint on the body of that task does not currently
work:

    (gdb) b pck.dummy_task
    "pck.dummy_task" is not a function
    Make breakpoint pending on future shared library load? (y or [n]) n

What happens here is that the compiler generates two symbols:

  (a) Symbol `pck__dummy_task' which is a *variable* referencing
      the task;

  (b) Symbol `pck__dummy_taskTKB' which is the subprogram implementing
      the body of the task.

The symbol lookup only finds the variable before of the TKB suffix in
the subprogram name. This patch fixes the problem by adjusting the
ada-lang.c:is_name_suffix routine to recognize "TKB" suffixes.  But
that's not enough, because the search in the symtab is performed via
the block dictionary, using a hashing algorithm. So, for the search
to find `pck__dummy_taskTKB', I had to modify the hashing function
to ignore TKB suffixes as well.

gdb/ChangeLog:

        * ada-lang.c (is_name_suffix): Add handling of "TKB" suffixes.
        Update function documentation.
        * dictionary.c (dict_hash): Ignore "TKB" suffixes in hash
