Dump SP on poll, and show whether it's MSP or PSP.

Thread mode can use either stack pointer, so this is
part of the state that's not yet displayed.

Shrink some lines.

Clean up treatment of registers in ARMv7-M and Cortex-M3. 

 - At the arch level:
    * Just list registers and names; don't impose core-specific
      policy about how they are accessed.
    * Each register has a symbol.
    * Remove the register mode field (irrelevant to debugger)

 - At the core/implementation level:
    * Just map the registers to their relevant access methods;
      don't require the arch level to say how that should work
      (cores other than Cortex-M3 could do it differently).
    * Don't use undefined bits from register 20.
    * Use register IDs that are part of the ARMv7-M interface.

In short, there's now a real distinction between the arch
and core layers.

Minor updates to the Thumb2 disassembly:

 - Bugfixes:
    * Distinguish branch from misc via "!=" not "=="
    * MRS register shift is 8 bits (vs MSR being 16)
 - Format tweaks:
    * CPS needed tab (not space)
    * add commma before some shifts
    * add space after comma in LDM/STM
    * use ".W" width spec on various instructions

Revert parts of the previous ARMv7-M register patch.
It turns out that part of the issue is a documentation
problem for the Cortex-M3 r1 parts. So for the rest,
simpler fixes are possible (in followup patch).

zwelch 16e17ab1b3 Magnus Lundin <lundin@mlu.mine.nu>, Oyvind Harboe <oyvind.harboe@zylin.com>, David Brownell <david-b@pacbell.net>:
Some cleanup of the ARMv7-M support:

 - Reference the relevant ARMv7-M ARM doc (DDI 0405C to non-Vendors), and
   update the Cortex-M3 doc refs (DDI 0337C is no longer available).

 - Those registers aren't actually general, and some are incorrect (per all
   public docs anyway).  Update comments and code accordingly.

     * What the Core Debug facility exposes is *implementation-specific*
       not architectural.  These values aren't fully portable.  They match
       Cortex-M3 ... so no current implementation will make trouble, but
       the next v7m implementation might.

     * Four of the registers are actually not exposed that way.  Before
       Cortex-M3 r2p0 they are read/written through MRS/MSR instructions.
       In that newest silicon, they are four bytes in one register, not
       four separate registers.

 - Update the CM3 code to report when that one register is available,
   and not try to access it when it isn't.  Also declare the register
   numbers that an eventual MRS/MSR solution will need to be using.

 - Stop line wrapping the exception labels.

So for parts before r2p0 OpenOCD behavior is effectively unchanged, and
still buggy; but for those newer parts a few things might now be correct.

Most current Cortex-M3 parts use r1p1 (or earlier); this seems to include
most LM3S parts and all STM32 parts.  Parts using r2p0 are available, and
include fourth generation LM3S parts ("Tempest") plus AT91SAM3 and LPC17xx
parts which are now sampling.

Make the Thumb2 disassembler handle a bunch of 32-bit instructions:

  A5.3.4 Branches and miscellaneous control
 
Note that this shifts some responsabililty out of helper functions,
making the code and layout simpler for 32-bit decoders:  they only
need to know how to format the instruction and its parameters.

Also, technical note:  with this patch, Thumb1 decoders could now
call the Thumb2 decoder if they wanted to get nicer treatment of
the exiting 32-bit B/BLX instructions.

zwelch b71e3aff6d David Brownell <david-b@pacbell.net>:
Change layout of Thumb disassembly to work better with Thumb2:

 - Move opcode to the left, allowing space for four hex bytes:
    * after address, two spaces not one tab (taking 6 spaces)
    * after 2-byte opcode, four spaces before tab
 - Also, after opcode mnemonic use a tab not a space, to make
   operands line up

Sample output (after some patches decoding a few 32-bit instructions):

0x00003e5a  0xf4423200	ORR	r2, r2, #131072	; 0x20000
0x00003e5e  0x601a    	STR 	r2, [r3, #0x0]
0x00003e60  0x2800    	CMP	r0, #0x00
0x00003e62  0xd1f3    	BNE	0x00003e4c
0x00003e64  0xf008fa38	BL	0x0000c2d8

The affected lines of code now wrap at sane margins too.

zwelch 309870e414 David Brownell <david-b@pacbell.net>:
Initial support for disassembling Thumb2 code.  This works only for
Cortex-M3 cores so far.  Eventually other cores will also need Thumb2
support ... but they don't yet support any kind of disassembly.

 - Update the 16-bit Thumb decoder:
 
     * Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added
       by ARMv6.  (It already seems to treat CPY as MOV.)

     * Understand CB, CBNZ, WFI, IT, and other opcodes added by
       in Thumb2.

 - A new Thumb2 instruction decode routine is provided.
 
     * This has a different signature:  pass the target, not the
       instruction, so it can fetch a second halfword when needed.  
       The instruction size is likewise returned to the caller.

     * 32-bit instructions are recognized but not yet decoded.
   
 - Start using the current "UAL" syntax in some cases.  "SWI" is
   renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM".

 - Define a new "cortex_m3 disassemble addr count" command to give
   access to this disassembly.

Sanity checked against "objdump -d" output; a bunch of the new
instructions checked out fine.
