3fb7683bec Normalize SourceMgr messages.
- Don't print "Parsing" in front of every message.

 - Take additional "type" argument which is prepended to the message (with ": ")
   if given.

 - Update clients to print errors (warnings) as:
<filename>:<line number>: error(warning): ...

2bc29dc0bc Add LLVMContext, which will eventually be used as a container for privatizing a lot of (currently) global state, including the
constant and type uniquing tables.  For now, just make it a wrapper around the existing APIs.

- For example, we diagnose errors on:

--
.long a
a = 10

4b35f83b91 Teach LoopSimplify how to merge multiple loop exits into a single exit,
when one of them can be converted to a trivial icmp and conditional
branch.

This addresses what is essentially a phase ordering problem.
SimplifyCFG knows how to do this transformation, but it doesn't do so
if the primary block has any instructions in it other than an icmp and
a branch. In the given testcase, the block contains other instructions,
however they are loop-invariant and can be hoisted. SimplifyCFG doesn't
have LoopInfo though, so it can't hoist them. And, it's important that
the blocks be merged before LoopRotation, as it doesn't support
multiple-exit loops.

667d787c0a Incorporate the insertion point into the key of SCEVExpander's CSE map.
This helps it avoid reusing an instruction that doesn't dominate all
of the users, in cases where the original instruction was inserted
before all of the users were known.  This may result in redundant
expansions of sub-expressions that depend on loop-unpredictable values
in some cases, however this isn't very common, and it primarily impacts
IndVarSimplify, so GVN can be expected to clean these up.

This eliminates the need for IndVarSimplify's FixUsesBeforeDefs,
which fixes several bugs.

505e982040 fix a really subtle bug in the cross section of aliases and TLS:
the SelectionDAG::getGlobalAddress function properly looks through
aliases to determine thread-localness, but then passes the GV* down
to GlobalAddressSDNode::GlobalAddressSDNode which does not.  Instead
of passing down isTarget, just pass down the predetermined node
opcode.  This fixes some assertions with out of tree changes I'm 
working on.

02a6218774 Increase limit for OpActions array
The OpActions array had a limit of 32 value types, so change it to use
MVT::MAX_ALLOWED_VALUETYPE in its declaration and change the accesses to
this array to work with a VT.getSimpleVT() that is larger than 32.

Also, add a comment to the place where MVT::MAX_ALLOWED_VALUETYPE is
defined indicating that it must be a multiple of 32.

This is part of the work allow MVT::LAST_VALUETYPE be greater than 32.

f2e19d5dcf This increases the maximum for MVT::LAST_VALUETYPE
This change doubles the allowable value for MVT::LAST_VALUETYPE. It does
this by doing several things.

1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a
value of 64.  This value contains the current maximum for the
MVT::LAST_VALUETYPE.

2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses
now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE"

3. Changes the dimension of the ValueTypeActions from 2 elements to four
elements and adds comments ahead of the declaration indicating the it is
"(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2".  This at least lets us find
what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets
changed.

4. Adds initializers for the new elements of ValueTypeActions.

This does NOT add any types in MVT. That would be done separately.

This doubles the size of ValueTypeActions from 64 bits to 128 bits and
gives us the freedom to add more types for AVX.

40a5a1b39e Extend ScalarEvolution's multiple-exit support to compute exact
trip counts in more cases.

Generalize ScalarEvolution's isLoopGuardedByCond code to recognize
And and Or conditions, splitting the code out into an
isNecessaryCond helper function so that it can evaluate Ands and Ors
recursively, and make SCEVExpander be much more aggressive about
hoisting instructions out of loops.

test/CodeGen/X86/pr3495.ll has an additional instruction now, but
it appears to be due to an arbitrary register allocation difference.

430444b102 Fix a serious bug that would cause deadlock during abstract type refinement. The constant creation
gets involved, and we end up trying to recursively acquire a writer lock.  The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.

475370b036 Add some scaffolding for a new experimental asmprinter
implementation.  The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst.  MCInst
and the new asmprinters will not depend on most of the 
llvm code generators.  This allows building diassemblers
that don't link in the whole llvm code generator.  This is
step #1 of many.

f9f1da17f8 - Update register allocation hint after coalescing. This is done by the target since the hint is target dependent. This is important for ARM register pair hints.

358dec5180 Part 1.
- Change register allocation hint to a pair of unsigned integers. The hint type is zero (which means prefer the register specified as second part of the pair) or entirely target dependent.
- Allow targets to specify alternative register allocation orders based on allocation hint.

Part 2.
- Use the register allocation hint system to implement more aggressive load / store multiple formation.
- Aggressively form LDRD / STRD. These are formed *before* register allocation. It has to be done this way to shorten live interval of base and offset registers. e.g.
v1025 = LDR v1024, 0
v1026 = LDR v1024, 0
=>
v1025,v1026 = LDRD v1024, 0

If this transformation isn't done before allocation, v1024 will overlap v1025 which means it more difficult to allocate a register pair.

- Even with the register allocation hint, it may not be possible to get the desired allocation. In that case, the post-allocation load / store multiple pass must fix the ldrd / strd instructions. They can either become ldm / stm instructions or back to a pair of ldr / str instructions.

This is work in progress, not yet enabled.

ca399021d4 Add an early implementation of a partial inlining pass. The idea behind this
is that, for functions whose bodies are entirely guarded by an if-statement, it
can be profitable to pull the test out of the callee and into the caller.

This code has had some cursory testing, but still has a number of known issues
on the LLVM test suite.

f5aefbdb79 Change IndexedModeAction representation.
This changes the IndexedModeAction representation to remove the
limitation on the number of value types in MVT.  This limitation
prevents us from specifying AVX types.

Prior to this change IndexedModActions was represented as follows...

uint64_t IndexedModeActions[2][ISD::LAST_INDEXED_MODE];

the first dimension was used to represent loads, then stores.  This
imposed a limitation of 32 on the number of value types that could be
handled with this method.  The value type was used to shift the two bits
into and out of the approprate bits in the uint64_t.

With this change the array is now represented as ...

uint8_t IndexedModeActions[MVT::LAST_VALUETYPE][2][ISD::LAST_INDEXED_MODE];

Takes more space but removes the limitation on MVT::LAST_VALUETYPE.  The
first dimension is now the value_type for the reference.  The second
dimension is the load [0] vs. store[1].  The third dimension represents
the various modes for load store.  Accesses are now direct, no shifting
or masking.

There are other limitations that need to be removed, so that
MVT::LAST_VALUETYPE can be greater than 32.  This is merely the first
step towards that goal.

type.

a5f54a06b0 Create FunctionType::isValidArgumentType to go along with isValidReturnType.
Also create isValidElementType for ArrayType, PointerType, StructType and
VectorType.

Make LLParser use them. This closes up some holes like an assertion failure on:

  %x = type {label}

but largely doesn't change any semantics. The only thing we accept now which
we didn't before is vectors of opaque type such as "<4 x opaque>". The opaque
can be resolved to an int or float when linking.
