the latter is capable of representing either a primitive or an extended type.

no longer needs a targetmachine to initialize itself.

dfab291702 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC 
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.

3a21425dbe Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to 
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.

b0abb4dc42 Use vAny type to get rid of Neon intrinsics that differed only in whether 
the overloaded vector types allowed floating-point or integer vector elements.
Most of these operations actually depend on the element type, so bitcasting
was not an option.

If you include the vpadd intrinsics that I updated earlier, this gets rid
of 20 intrinsics.

for emission, so they do not as yet have patterns.

1b747ad8a0 SjLj based exception handling unwinding support. This patch is nasty, brutish 
and short. Well, it's kinda short. Definitely nasty and brutish.

The front-end generates the register/unregister calls into the SjLj runtime,
call-site indices and landing pad dispatch. The back end fills in the LSDA
with the call-site information provided by the front end. Catch blocks are
not yet implemented.

Built on Darwin and verified no llvm-core "make check" regressions.

ld: bad offset (0x00000091) for lo14 instruction pic-base fix-up in ___popcountdi2 from libgcc/./_popcountsi2_s.o

on ppc64 and .section doesn't have an implicit alignment like ".non_lazy_symbol_pointer"
does.

ff4bc460c5 Make the big switch: Change MCSectionMachO to represent a section *semantically* 
instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?

a3741fa28b llvm-mc/AsmMatcher: Improve match code. 
- This doesn't actually improve the algorithm (its still linear), but the
   generated (match) code is now fairly compact and table driven. Still need a
   generic string matcher.

 - The table still needs to be compressed, this is quite simple to do and should
   shrink it to under 16k.

 - This also simplifies and restructures the code to make the match classes more
   explicit, in anticipation of resolving ambiguities.

20927f26fc llvm-mc/AsmMatcher: Move to a slightly more sane matching design. 
- Still not very sane, but a least its not 60k lines on X86. :)

 - In terms of correctness, currently some things are hard wired for X86, and we
   still don't properly resolve ambiguities (this is ignoring the instructions
   we don't even match due to funny .td stuff or other corner cases).

The high level changes:
 1. Represent tokens which are significant for matching explicitly as separate
    operands. This uniformly handles not only the instruction mnemonic, but
    also 'signficiant' syntax like the '*' in "call * ...".

 2. Separate the matching of operands to an instruction from the construction of
    the MCInst. In theory this can be done during matching, but since the number
    of variations is small I think it makes sense to decompose the problems.

 3. Improved a few of the mechanisms to at least successfully flatten / tokenize
    the assembly strings for PowerPC and ARM.

 4. The comment at the top of AsmMatcherEmitter.cpp explains the approach I'm
    moving towards for handling ambiguous instructions. The high-bit is to infer
    a partial ordering of the operand classes (and force the user to specify one
    if we can't) and use that to resolve ambiguities.

861986401e It turns out most of the thumb2 instructions are not allowed to touch SP. The semantics of such instructions are unpredictable. We have just been lucky that tests have been passing. 
This patch takes pain to ensure all the PEI lowering code does the right thing when lowering frame indices, insert code to manipulate stack pointers, etc. It's also custom lowering dynamic stack alloc into pseudo instructions so we can insert the right instructions at scheduling time.

This fixes PR4659 and PR4682.

24f654c8a4 Fix several fixmes and clean up code by sinking *all* section 
creation activity into the target-specific subclasses of TLOF.
Before this, globals with explicit sections could be created by
the base class.

1. make getOrCreateSection protected, add a new getExplicitSectionGlobal
   pure virtual method to assign sections to globals with a specified
   section.
2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific.
3. eliminate the getKindForNamedSection virtual method, which is
   now just a static method for ELF.
4. Add implementions of getExplicitSectionGlobal for ELF/PECOFF/Darwin/PIC16.
   They are now all detangled and understandable, woo! :)

70cd88fb7b Add a new pre-allocation pass to assign adjacent registers for Neon instructions 
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.
