Misha Brukman 67a1ffa59c Reversed order of args in EXPECT_EQ() macros to be in the correct order:
EXPECT_EQ(expected, actual) .  This will make error messages understandable as
it uses terms such as "expected" and "actual" based on the order of arguments.

identical function ConstantIsDead() to SafeToDestroyConstant(), to

Owen Anderson f6df30852b Add the beginnings of an implementatation of lazy liveness analysis, based on "Fast Liveness Checking for SSA-form Programs" by Boissinot, et al.
This is still very early, hasn't been tested, and is not yet well documented.  More to come soon.

Bill Wendling e05336f80d I'm going to assume that this was meant to be an assignment instead of a
computation that isn't used. Please correct this if it's wrong!

Dan Gohman b8597bd097 Use expandCodeFor instead of expand when the result will be
immediately casted. At present, this is just a minor code
simplification. In the future, the expansion code may be able
to make better choices if it knows what the desired result
type will be.

Sanjiv Gupta 7607eba036 PIC16 emits auto variables as globals. When optimizer removes a function entierly by estimating its side effects on globals, those globals(autos) without a function were not being printed by the Asm printer.

David Greene a31cbba1cd 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.

Nick Lewycky 0aa6a74a79 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.

Eli Friedman 3234587213 Slightly generalize the code that handles shuffles of consecutive loads
on x86 to handle more cases.  Fix a bug in said code that would cause it 
to read past the end of an object.  Rewrite the code in 
SelectionDAGLegalize::ExpandBUILD_VECTOR to be a bit more general. 
Remove PerformBuildVectorCombine, which is no longer necessary with 
these changes.  In addition to simplifying the code, with this change, 
we can now catch a few more cases of consecutive loads.
