As Eric pointed out, even a Debug build should be equal. Leave the flag that can turn off comparisons though.

Fixes to r153903.  Added missing explanation of behaviour when the VirtRegMap is NULL.  Also changed it in this case to just avoid updating the map, but live ranges or intervals will still get updated and created

This is just the fallback tie-breaker ordering, the main allocation
order is still descending size.

Patch by Shamil Kurmangaleev!

llvm-svn: 153904

Refactored the LiveRangeEdit interface so that MachineFunction, TargetInstrInfo, MachineRegisterInfo, LiveIntervals, and VirtRegMap are all passed into the constructor and stored as members instead of passed in to each method.

Add predicates for checking whether targets have free FNEG and FABS operations, and prevent the DAGCombiner from turning them into bitwise operations if they do.

Fixes PR11861.

This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

The test case checks for both big and little endian flavors.

We have not trivial way for splitting edges that are goes from indirect branch. We can do it with some tricks, but it should be additionally discussed. And it is still dangerous due to difficulty of indirect branches controlling.

Fix forbids this case for unswitching.

reflected in the LLVM IR (as a declare or something), then treat it like a data
object.

N.B. This isn't 100% correct. The ASM parser should supply more information so
that we know what type of object it is, and what attributes it should have.

Reorder fields in MatchEntry and OperandMatchEntry to reduce padding. A bit tricky due to the target specific sizes for some of the fields so the ordering is only optimal for the targets in the tree.

Do not try to optimize swizzles of shuffles if the source shuffle has more than
a single user, except when the source shuffle is also a swizzle.

Remove getInstructionName from MCInstPrinter implementations in favor of using the instruction name table from MCInstrInfo. Reduces static data in the InstPrinter implementations.

Patch by Jeremy Huddleston!

llvm-svn: 153862

Make MCInstrInfo available to the MCInstPrinter. This will be used to remove getInstructionName and the static data it contains since the same tables are already in MCInstrInfo.

rather than a bitfield, a great suggestion by Chris during code review.

There is still quite a bit of cruft in the interface, but that requires
sorting out some awkward uses of the cost inside the actual inliner.

No functionality changed intended here.
