remote packet sent after Ravenscar inferior exited

When debugging a program using the Ravenscar profile, the debugger
sometimes tries to send the following packet to the remote after
the inferior exited.

     (gdb) c
     Continuing.
     [...]
     Sending packet: $vCont;c:1#13...Ack
     Packet received: W00
     Sending packet: $Hg1#e0...putpkt: write failed: Broken pipe.

As the inferior exited, the remote has already disconnected, and thus
the operation fails.

The reason why GDB sends the package is because the ravenscar-thread
module tries to updates the list of threads.  But this doesn't make
sense, since the program has exited.  This patch fixes it.

gdb/ChangeLog:

        * ravenscar-thread.c (ravenscar_wait): Only update the list
        of threads and inferior_ptid if the inferior is still alive.

[Ada] use lbasename when testing if file is part of Ada runtime.

We use a list of regular expressions to match a symtab filenames
against the names of the files in the Ada runtime.  These regular
expressions do assume that the filename is a basename, however.
So make sure to evaluate these regular expressions against
the symtab's filename.

Without this patch, we run into problems when the Ada runtime was built
using a project file (through gprbuild).

gdb/ChangeLog:

        * ada-lang.c (is_known_support_routine): Use lbasename when
        matching the symtab's filename against
        known_runtime_file_name_patterns.

[Ada] Allow assignment to wide string.

Given the following variable declaration...

   Www : Wide_String := "12345";

... this patch allows the following assignment to work:

   (gdb) set variable www := "qwert"

Without this patch, the debugger rejects the assignment because
the size of the array elements are different:

   (gdb) set www := "asdfg"
   Incompatible types in assignment

(on the lhs, we have an array of 2-bytes elements, and on the rhs,
we have a standard 1-byte string).

gdb/ChangeLog:

        * ada-lang.c (ada_same_array_size_p): New function.
        (ada_promote_array_of_integrals): New function.
        (coerce_for_assign): Add handling of arrays where the elements
        are integrals of a smaller size than the size of the target
        array element type.

gdb/testsuite/ChangeLog:

        * gdb.ada/set_wstr: New testcase.

off-by-one max exponent computation in convert_doublest_to_floatformat

Assuming the following variable definition:

    long double inp = 2.0;

On platforms where "long double" is a double precision IEEE flaoting
point, GDB currently behaves as follow:

    (gdb) set variable inp = 1.6e+308l
    (gdb) p inp
    $2 = inf   <<<<---- !!!!

Instead, the value of "inp" should be printed as:

    (gdb) p inp
    $1 = 1.6e+308

The problem is due to a small error in the comparison of the exponent
versus the maximum value this exponent can take, causing us to think
that the value was too big to fit. But it isn't.

gdb/ChangeLog:

        * doublest.c (convert_doublest_to_floatformat): Fix comparison
        against maximum exponent value.

        * gdb.base/ldbl_e308.c, gdb.base/ldbl_e308.exp: New files.

[Ada] Skip unwind-seh.c when searching first "user" frame

On x86_64-windows with GCC 4.7 (using native SEH info), the debugger
behaves as follow:

    (gdb) catch exception unhandled
    Catchpoint 1: unhandled Ada exceptions
    (gdb) run
    Starting program: C:\[...]\b.exe

    Catchpoint 1, unhandled CONSTRAINT_ERROR at 0x000000000040cc57 in _GCC_specific_handler ([...]) at ../../../src/libgcc/unwind-seh.c:289
    [...]

This is after compiler the following code:

    procedure B is
    begin
       raise Constraint_Error;
    end B;

... using the following command:

    % gnatmake -g b

When hitting the exception catchpoint, it should have gone up the stack
all the way until finding the frame corresponding to procedure B.
But if stopped short because unwind-seh.c is compiled with debugging
information, and the debugger is also able to locate that source file.

To prevent this from happening, this patch adds unwind-seh.c to the list
of files that should be ignored, regardless of other factors.

gdb/ChangeLog:

        * ada-lang.h (ADA_KNOWN_RUNTIME_FILE_NAME_PATTERNS): Add entry for
        "unwind-seh.c".

[Ada] Pointers to unconstrained arrays inside variant record.

gdb/ChangeLog:

        * ada-lang.c (ada_template_to_fixed_record_type_1): Do not

[Windows] run program with space in path to exe.

The following works...

    % gdb c:\path to exe\foo.exe
    (gdb) start

... unless a file or directory called "c:\path" or "c:\path to" exist.
This is what happens in the latter case:

    (gdb) start
    [...]
    Error creating process C:\path to exe\foo.exe (error 193).

This is because we are calling CreateProcess (et al) without specifying
the lpApplicationName, so Windows determines the name of the executable
using the second argument, which is the entire command line.  This
command line is a space-separated list of tokens, so the space in
the path to the executable which potentially creates an ambiguity.
The ambiguity is automatically resolved unless we're in the situation
above.

The solution, as suggested by the MSDN documentation for CreateProcess
is to quote the executable name.

gdb/ChangeLog:

        * windows-nat.c (windows_create_inferior) [!__CYGWIN__]:

ppc-aix osabi sniffer: Turn test of bfd flavour into assertion

Due to the way this function is registers, we know that given bfd's
flavour should always be bfd_target_xcoff_flavour, thus making
the former test always true, which means that this function should
always return GDB_OSABI_AIX, and never return GDB_OSABI_UNKNOWN.

This patch also fixes a typo detected by Tom Tromey that caused
the test itself to be completely ineffective.

gdb/ChangeLog (by Tom Tromey and Joel Brobecker):

        * rs6000-aix-tdep.c (rs6000_aix_osabi_sniffer): Replace
        inneffective if condition by gdb assertion.  Add function
        description comment.

Document exp_descriptor.op_name should never return NULL.

This documents a constaint that struct exp_descriptor's "op_name"
method implementation should obey.  This might not have been part
of the initial design, but is currently true of all instantiations,
and already assumed by the current users.

gdb/ChangeLog:

        * parser-defs.h (struct exp_descriptor): Document constraint
        on return value for "op_name" callbacks.

* compress.c: Revert previous patch.

* compress.c (bfd_get_full_section_contents): Don't cache
decompressed contents.

Correct my ChangeLog entry

    * gdb.base/ctxobj.exp: Skip if skip_shlib_tests returns true.
        * gdb.base/print-file-var.exp: Likewise.
        * gdb.base/type-opaque.exp: Likewise.
