as well as completely defined classes.

This fixes rdar://10956070

llvm-svn: 152171

Extend r148086 to check for [r +/- reg] address mode. This fixes queens performance regression (due to increased register pressure from overly aggressive pre-inc formation).

Register pair, all lanes subscripting.

Register pair VLD1/VLD2 all-lanes instructions. Kill off more of the
pseudos as a result.

llvm-svn: 152150

Fix support for encodings up to 64-bits in length.  TableGen was silently truncating them to 32-bits prior to this.

SmallPtrSet: Provide a more efficient implementation of swap than the default triple-copy std::swap.

This currently assumes that both sets have the same SmallSize to keep the implementation simple,
a limitation that can be lifted if someone cares.

 - On OS X 10.7+ this is apparently recommended practice. This maybe should
   become a configurey thing one day, but I'm not sure it is right to
   automatically turn it on.

use the first pointer type for it. Rename it to getAddrOfPtr1().

llvm-svn: 152106

Use uint16_t to store indices into string table since C++ only allows 64K string literals so the index into the big string can never be larger than that.

llvm-svn: 152104

Increase number of allowed registers in register classes to 64k instead of 256. Widen register class ID to 16-bits. Widen register size and alignment to be up to 64k bytes instead of 256 bytes. This partially reverts r152019 to be less restrictive.

It is just a worse version of TinyPtrVector.

When an instruction only writes sub-registers, it is still necessary to
add an <imp-def> operand for the super-register.  When reloading into a
virtual register, rewriting will add the operand, but when loading
directly into a virtual register, the <imp-def> operand is still
necessary.

Abuse div and pre tags horribly. Needs a bit more cleanup.
