Let the generic token alias definitions handle the data subtype
suffices. We don't need explicit versions for each.

which doesn't appear to happen on the regression test suite, but obviously
happens in real life :)

revert r148688 too, this isn't safe for DenseMap use.  When DenseMap resizes, it will need to copy around arbitrary pointers

complexity and std::map'ness.

This change adds an new value to the --arm-enable-ehabi option that
disables emitting unwinding descriptors. This mode gives a working
backtrace() without the (currently broken) exception support.

Remove pattern fragments for v32i8, v16i16, v8i32, v16i8, v8i16, and v4i32 loads. All integer vector loads are promoted to v2i64 or v4i64 so these pattern fragments can never match. Fix or remove patterns that used these fragments.

returns false in the event the computation feeding into the pointer is
unreachable, which maybe ought to be true -- but this is at least consistent
with undef->isDereferenceablePointer().) Fixes PR11825!

Merge PCMPEQB/PCMPEQW/PCMPEQD/PCMPEQQ and PCMPGTB/PCMPGTW/PCMPGTD/PCMPGTQ X86 ISD node types into only two node types. Simplifying opcode selection and pattern matching.

Use Attributes::None instead of 0 after r148553 change on Attributes from unsigned to their own class.

Add target specific ISD node types for SSE/AVX vector shuffle instructions and change all the code that used to create intrinsic nodes to create the new nodes instead.

in a subclass named DyldELFObject. This class supports rebasing the object file
it represents by re-mapping section addresses to the actual memory addresses
the object was placed in. This is required for MC-JIT implementation on ELF with
debugging support.

Patch reviewed on llvm-commits.

Developed together with Ashok Thirumurthi and Andrew Kaylor.

ELF and MachO implementations of RuntimeDyldImpl go into their own header files now.

Unfortunately I don't think there's a fix for this that will work upstream and
also satisfy Clang's -Wunreachable-code, which is a pity. But I'll give it some
more thought -perhaps there's some way out.

Add memory patterns for some of the fp<->integer conversion instructions. Fold some patterns into instruction definitions.

This will ensure LLVM and Clang build -Wswitch-enum-redundant-default (an on-by-default warning I'm about to add to Clang).
