David Brownell 181d401d59 ARM: add is_arm_mode()
Add a new is_arm_mode() predicate, and use it to replace almost
all calls to current armv4_5_mode_to_number().

Eventually those internal mode numbers should vanish... along
with their siblings in the armv7a.c file.

Remove a handful of superfluous checks ... e.g. the mode number
was just initialized, or (debug entry methods) already validated.

Move one of the macros using internal mode numbers into the only
file which uses that macro.  Make the tables manipulated with
those numbers be read-only and, where possible, static so they're
not confused with part of the generic ARM interface.

David Brownell ec93209f51 ARM: add arm_mode_name()
Add and use arm_mode_name() to map from PSR bits to user
meaningful names.   It uses a new table which, later, can
be used to hold other mode-coupled data.

Add definitions for the "Secure Monitor" mode, as seen on
some ARM11 cores (like ARM1176) and on Cortex-A8.  The
previous mode name scheme didn't understand that mode.

Remove the old mechanism ... there were two copies, caused
by Cortex-A8 needing to add "Secure Monitor" mode support.

David Brownell d6c8945662 ARM: only use one set of dummy FPA registers
All ARM cores need to provide obsolete FPA registers in their
GDB register dumps.  (Even though cores with floating point
support now generally use some version of VFP...)

Clean up that support a bit by sharing the same dummy registers,
and removing the duplicate copies.  Eventually we shouldn't need
to export those dummies.

(This makes the ARMv7-M support include the armv4_5 header, and
cleans up related #includes, but doesn't yet use anything from
there except those dummies.)

Zachary T Welch 94975c96d4 update doxygen configuration to produce a PDF
A single PDF file for the developer manual allows accessing a single
index, browsing, and searching.  It takes significantly more time to
build this way, but this patch allows others to look at the results.

Migration Tip: If you have previously built the HTML Doxygen
documentatation, rename your 'doxygen' directory to 'doxygen/html'
to prevent needlessly rebuilding those files.

Zachary T Welch 5b9899d6ea add more command_handler conversion macros
Add additional macros to allow command handling to be migrated easily:
CMD_CTX, CMD_ARGC, and CMD_ARGV.  Updates CMD_NAME to use CMD_ARGV.

In addition to making the remaining patches of this series cleaner,
this introduces easily sed-able symbols that could allow us to retire
these once the command handler infrastructure matures (i.e. pre-1.0).

David Brownell f4788652e4 target: simplify register get/set ops
No need to indirect from registered integers to pointers.

and don't even bother registering.

This is a small code shrink, speeds register access just
a smidgeon, and gets rid of another rude exit() path.

Zachary T Welch 51862bb98c fileio: improve API types
Use size_t instead of uint32_t when specifying file sizes.  Update all
consumers up through the layers to use size_t when required.  These
changes should be safe, but the higher-levels will need to be updated
further to receive the intended benefits (i.e. large file support).

Add error checking for fileio_read and file_write.  Previously, all
errors were being silently ignored, so this change might cause some
problems for some people in some cases.  However, it gives us the chance
to handle any errors that do occur at higher-levels, rather than burying
our heads in the sand.

David Brownell 91ac164d95 ARM: standard disassembler uses Thumb2 entry
Tweak "standard" ARM disassembler diagnostics to fail if the target
is not "an ARM" (vs. not "an ARMV4/5"), so it makes more sense for
cores inheriting this as the "generic" disassembler.

Also, to use the Thumb2 entry instead of the original Thumb entry.
This makes it work better for both newer cores (which support those
added instructions) and for BL and BLX instructions on older cores.
(Those instructions are 32-bits, which requires curious state-aware
code to go through a 16-bit decode interface...)

Plus minor cleanups, notably to have fewer exit paths and to make
sure they all return failure codes.
