Doc 'dynamic' for command -var-list-children

Hi,
I find "dynamic=1" appear in the result of each child of the output of
-var-list-children,

-var-list-children ss1
^done,numchild="2",children=[child={name="ss1.a",exp="a",numchild="0",type="struct s",thread-id="1",dynamic="1"},child={name="ss1.b",exp="b",numchild="0",type="struct s",thread-id="1",dynamic="1"}],has_more="0"

but the doc doesn't mention this. This patch is to copy the description
of "dynamic=1" here.

get rid of py-value.c:is_intlike (use is_integral_type instead)

is_intlike was mostly duplicating is_integral_type, with the exception
of the handling of TYPE_CODE_PTR when parameter PTR_OK is nonzero.
This patches deletes the is_intlike function, using is_integral_type
instead, and adjusting the two locations where this function gets
called.

The code should remain strictly equivalent.

gdb/ChangeLog:

* python/py-value.c (is_intlike): Delete.
(valpy_int): Replace use of CHECK_TYPEDEF and is_intlike
by use of is_integral_type.
(valpy_long): Replace use of CHECK_TYPEDEF and is_intlike
by use of is_integral_type and check for TYPE_CODE_PTR.

Make the maint.exp:'maint print objfiles' test less fragile.

I was "lucky" enough that an unrelated patch changed how many symtabs
GDB expands in a plain run to main, and that triggered a latent issue
in this test:

PASS: gdb.base/maint.exp: maint print objfiles: header
PASS: gdb.base/maint.exp: maint print objfiles: psymtabs
FAIL: gdb.base/maint.exp: maint print objfiles: symtabs

The problem is in my case, expect is managing to alway put in the
buffer chunks like this:


Psymtabs:
../../../src/gdb/testsuite/gdb.base/break1.c at 0x1ed2280, ../../../src/gdb/testsuite/gdb.base/break.c at 0x1ed21d0,

Symtabs:
../../../src/gdb/testsuite/gdb.base/break.c at 0x1f044f0, /usr/include/stdio.h at 0x1ed25a0, /usr/include/libio.h at 0x1ed2510, /usr/include/bits/types.h at 0x1ed2480, /usr/lib/gcc/x86_64-redhat-linux/4.7.2/include/stddef.h at 0x1ed23f0,


Object file /usr/lib/debug/lib64/ld-2.15.so.debug: Objfile at 0x1f4bff0, bfd at 0x1f2d940, 0 minsyms

Psymtabs:
bsearch.c at 0x1f65340, ../sysdeps/x86_64/multiarch/init-arch.c at
0x1f65290, ...

Note: Psymtabs:/Symtabs:/Psymtabs:.

So, the loop matches the first Psymtabs in the buffer. Then we're
left with


../../../src/gdb/testsuite/gdb.base/break1.c at 0x1ed2280, ../../../src/gdb/testsuite/gdb.base/break.c at 0x1ed21d0,

Symtabs:
../../../src/gdb/testsuite/gdb.base/break.c at 0x1f044f0, /usr/include/stdio.h at 0x1ed25a0, /usr/include/libio.h at 0x1ed2510, /usr/include/bits/types.h at 0x1ed2480, /usr/lib/gcc/x86_64-redhat-linux/4.7.2/include/stddef.h at 0x1ed23f0,


Object file /usr/lib/debug/lib64/ld-2.15.so.debug: Objfile at 0x1f4bff0, bfd at 0x1f2d940, 0 minsyms

Psymtabs:
bsearch.c at 0x1f65340, ../sysdeps/x86_64/multiarch/init-arch.c at
0x1f65290, ...

In the next iteration, because the psymtabs regex comes first, we
match with the Psymtabs: line, then of course, end up with just

bsearch.c at 0x1f65340, ../sysdeps/x86_64/multiarch/init-arch.c at
0x1f65290, ...

in the buffer. The "Symtabs:" line is lost. expect then reads more
gdb output, and manages to again retrieve the same pattern. Rinse,
repeat, and the test never matches any "Symtab:" line.

We don't know the order the matches lines will appear, so the fix is
to consume one line at a time, and run it through all three milestone
regexes.

remove strerror module

This fixes the mingw build breakage reported by Pierre.

I found that the gnulib strerror module somehow requires us to pull in
the gethostname module. However, pulling in the gethostname module
makes many things break.

I've sent a bug report to gnulib.

Meanwhile, removing the strerror module should not harm gdb and fixes
the build.

I'm checking this in.

Fix conditions in creating a bitfield.

Bitfields are represented by intervals [start, begin]. It means that for an

gdb/arm-tdep.c: Remove "Infinite loop detected" error message.

Since as far back as the beginning of the sourceware repository
the ARM port has printed an error "Infinite loop detected" when
the next_pc calculated is the same as the current one, for example
when encountering a branch to the current PC address.

This causes the test gdb.base/random-signal.exp as the error message
is not expected. I have not been able to find a good reason for the

instead of remote data.
