fcfe355efd Be more clever about regclasses in ScheduleDAGSDNodes::EmitCopyFromReg. 
If two uses of a CopyFromReg want different regclasses, first try a common
sub-class, then fall back on the copy emitted in AddRegisterOperand. There is
no need for an assert here. The cross-class joiner usually cleans up nicely.

ca19f19760 Fix for PR3016: detect the tricky case, where there are 
unfoldable references to a PHI node in the block being folded, and disable
the transformation in that case.  The correct transformation of such PHI
nodes depends on whether BB dominates Succ, and dominance is expensive 
to compute here.  (Alternatively, it's possible to check whether any 
uses are live, but that's also essentially a dominance calculation. 
Another alternative is to use reg2mem, but it probably isn't a good idea to
use that in simplifycfg.)

Also, remove some incorrect code from CanPropagatePredecessorsForPHIs 
which is made unnecessary with this patch: it didn't consider the case 
where a PHI node in BB has multiple uses.

ca89ccb1dd implement support for lowering references to global addresses. For example, we now 
can asmprint:

NEW: 	movl	"L___stack_chk_guard$non_lazy_ptr", %eax
OLD: 	movl	L___stack_chk_guard$non_lazy_ptr, %eax

where 'new' is coming out of the MCInst version of the printer.

696d0388e9 An overhaul of the exception handling code. This is arguably more correct than 
what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.

I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)

7f4ef2d59a Refine EarlyClobber assert in register scavenger. 
It is legal for an inline asm operand to use an earlyclobber register if the
use operand is tied to the earlyclobber operand. The issue is discussed here:

  http://gcc.gnu.org/ml/gcc/1999-04n/msg00431.html

We should perhaps let only the machine code verifier worry about these finer
details. EarlyClobber operands are not really interesting to the scavenger.

This fixes PR4528 for the third time.

8f6660c417 Don't setCalleeSavedInfoValid() until spills are interted. 
In a naked function, the flag is never set and getPristineRegs() returns an
empty list. That means naked functions are able to clobber callee saved
registers, but that is the whole point of naked functions.

Now that more things are using WriteAsOperand, its behavior of

the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

29efb6cf1f add a couple of helpers to the Triple class for decoding 
the darwin version string.  This should help consolidate
the variety of weird functions we have scattered around the
codebase that do stuff like this.

a74023896f Change the asmprinter to print the comment character before the

are separate from the comment character.  This lets elf targets

character.  This also allows hoisting the darwin stuff up to the
shared TAI class.

63f93255ae Add 'isCodeGenOnly' bit to Instruction .td records. 
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.

45bdc96988 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.

434a66fa9b 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.
