Joel Brobecker [Tue, 27 Dec 2011 04:03:58 +0000 (04:03 +0000)]
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.

gdb/ChangeLog:

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

12 years agomissing check against overlay_debugging in objfiles.c
Joel Brobecker [Wed, 21 Dec 2011 07:11:52 +0000 (07:11 +0000)]
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.

12 years ago[Ada] Breakpoints on task bodies
Joel Brobecker [Wed, 21 Dec 2011 07:10:59 +0000 (07:10 +0000)]
[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.

Work around Solaris bourne shell limitation when building the sim

Building the sim on a sparc-solaris 2.8 machine fails when configured
with no extra sim hardware:

> for hw in  ; do \
>         echo "extern const struct hw_descriptor
>         dv_${hw}_descriptor[];" ; \
>       done >> tmp-hw.h

> /bin/sh: -c: line 1: `for hw in  ; do \'
> make[3]: *** [hw-config.h] Error 2

The same thing happens with the version of bash that we got from
Sun as well (which is very old: 2.03.0(1)-release).

The problems comes from the fact that both shells are buggy, and
reject the following script:

    for hw in ; do
      [...]
    done

The above is what sim/common/Makefile.in tries to execute when
generating hw-config.h.

In order to allow users to build out of the box on these machines,
this patch works around this bug.  It does rely on the fact that
none of the tokens in SIM_HW contain whitespaces.

        * Make-common.in (hw-config.h): Work around bug in Solaris 2.8
