47728a2819 remove Mangler::getTypeID and related data, it was only used for mangling 
local symbols and we haven't had type planes since llvm 1.9.

762717acb1 remove mangler support for mangling local names. Mangler should only be 
used with globals.

d4f53b373e Two changes: 
1) unique globals with the existing "Count" local in Mangler, not with
atomic nonsense.  Using atomics will give us nondeterminstic output
from the compiler when using multiple threads, which is bad.

2) Do not mangle an unknown global name with a type suffix.  We don't
   need this anymore now that llvm ir doesn't have type planes.

16a2c927e9 Move isLCSSAForm, isLoopInvariant, getCanonicalInductionVariable, 
and related functions out of LoopBase and into Loop, since they
are specific to BasicBlock-based loops. This also allows the code
to be moved out-of-line.

c8d76d5afb Make Loop and MachineLoop be subclasses of LoopBase, rather than typedefs, 
using the Curiously Recurring Template Pattern with LoopBase.

This will help further refactoring, and future functionality for
Loop. Also, Headers can now foward-declare Loop, instead of pulling
in LoopInfo.h or doing tricks.

65445c5b14 Misc simplifications to InstCombiner::commonIntCastTransforms. Most of

014700c1a8 Add infrastructure to allow post instruction printing action triggers. 
We'll eventually use this to print comments in asm files and do other

This adds interfaces to the AsmPrinter and changes TableGen to invoke
the postInstructionAction when appropriate.  It also add parameters to
TargetAsmInfo to control comment layout.

6fbc1969e9 Move the re-sort of invalidated NonLocalPointerDeps cache earlier 
so that all code paths get it.  PR4256 was about a case where the
phi translation loop would find all preds in the Visited cache, so
it could get by without re-sorting the NonLocalPointerDeps cache.
Fix this by resorting it earlier, there is no reason not to do this.

This patch inspired by Jakub Staszak's patch.

0a5372ed3e Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

eaff524670 remove llvm.part.set.* and llvm.part.select.*. They have never been 
implemented in codegen, have no frontend to generate them, and are 
better implemented with pattern matching (like the ppc backend does
to generate rlwimi/rlwinm etc).

65a7a6f7a3 fix x86-64 static codegen to materialize the address of a global with movl instead 
of lea.  It is better for code size (and presumably efficiency) to use:

  movl $foo, %eax

rather than:

  leal foo, eax

Both give a nice zero extending "move immediate" instruction, the former is just
smaller.  Note that global addresses should be handled different by the x86
backend, but I chose to follow the style already in place and add more fixme's.

4f06649497 Fix PR4533, which is about buggy codegen in x86-64 -static mode. 
Basically, using:
  lea symbol(%rip), %rax

is not valid in -static mode, because the current RIP may not be
within 32-bits of "symbol" when an app is built partially pic and
partially static.  The fix for this is to compile it to:

  lea symbol, %rax

It would be better to codegen this as:

  movq $symbol, %rax

but that will come next.


The hard part of fixing this bug was fixing abi-isel, which was actively
testing for the wrong behavior.  Also, the RUN lines are completely impossible
to understand what they are testing.  To help with this, convert the -static 
x86-64 codegen tests to use filecheck.  This is much more stable and makes it
more clear what the codegen is expected to be.

646ca92bfc Fix handling of max and full set. 
A full set is a constant range that represents any number. If you take the
umax of that and [5, 10) you end up with [5, INT_MAX] because the values less
than 5 would be umax's against a value which is at least 5.

446c428bf3 Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically. 
A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.
