now compile:

  X = 0;
}

into:

_test1:
        lis r2, ha16(_X)
        li r3, 0

Remove explicit casts to std::string now that there is no overload resolution
issues in the TargetData ctors.

llvm-svn: 28830

support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

llvm-svn: 28825

can in 32-bit mode we can choose to optionally *use* 64-bit registers.

llvm-svn: 28824

that is currently just like ppc32 :)

as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.

them.  This vastly simplifies the selection code, and moves the ABI handling
parts into one place.
