Move changelog entry to the right ChangeLog
Remove last_cache

This patch removes global variable 'last_cache', and initialize
'target_dcache' lazily, so that 'target_dcache' can replace
'last_cache'.  No functionalities should be changed after this patch.

gdb:

2013-11-20  Yao Qi  <yao@codesourcery.com>

	* dcache.c (last_cache): Remove.
	(dcache_free, dcache_init): Update.
	(dcache_update):
	(dcache_print_line): Add parameter 'dcache'.  Replace
	'target_dcache' with 'dcache'.

	(memory_xfer_partial_1): Adjust.
	(initialize_target): Don't initialize 'target_dcache'.
	* target.h (struct dcache_struct): Declare.
	(target_dcache_get): Declare.
Don't update target_dcache if it is not initialized

After previous patch, 'target_dcache' is initialized lazily.  It is
possible that 'target_dcache' is still NULL when GDB writes to memory.
In this case, update to 'target_dcache' can be skipped.

gdb:

2013-11-20  Yao Qi  <yao@codesourcery.com>

	* target.c (memory_xfer_partial_1): Update 'target_dcache' if

Don't stress 'remote' in "Data Caching" in doc

When I try to describe the cache and its related commands (in a
cache-per-address-space world), I find hard to add, because
existing doc is focused on remote debugging, while data cache is used
regardless of the target.  More precisely, GDB cache target data,
instead of remote data.

gdb/doc:

2013-11-20  Yao Qi  <yao@codesourcery.com>

	* gdb.texinfo (Data): Rename menu item.
	(Caching Remote Data): Rename to ...
	(Caching Target Data): ... it.  Update.
Add REGISTRY for struct address_space.

This patch adds REGISTRY for struct address_space.

Associate target_dcache to address_space.

Hi,
Nowadays, 'target_dcache' is a global variable in GDB, which is not
necessary.  It can be a per-address-space variable.  In this patch, we
associate target_dcache to address_space.

gdb/doc:

2013-11-20  Yao Qi  <yao@codesourcery.com>

	* gdb.texinfo (Caching Target Data): Update doc for
	per-address-space dcache.

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
message to be here so remove it and let the test pass.

gdb/ChangeLog:

2013-11-20  Will Newton  <will.newton@linaro.org>

	* arm-tdep.c (arm_get_next_pc): Remove "Infinite loop detected"
	error message.

Fix conditions in creating a bitfield.

Bitfields are represented by intervals [start, begin]. It means that for an
interval comprised by only one  bit start and end will be equal.
The present condition does not always hold. On the other hand in target-description.c
(tdesc_gdb_type) bitfield is created when "f->type" is null. The routine
maint_print_maint_print_c_tdesc_cmd is modified to follow the same strategy.

2013-11-20  Walfred Tedeschi  <walfred.tedeschi@intel.com>

	* target-descriptions.c (maint_print_maint_print_c_tdesc_cmd):
	Modified logic of creating a bitfield to be in sync with
	tdesc_gdb_type.

testsuite/
	* gdb.xml/maint_print_struct.xml (bitfield): Added bitfield having
	start and end equal 0.
