e59a7ee26a Implement ExpandOperationResult for ppc i64 fp->int, which fixes 
CodeGen/Generic/fp_to_int.ll among others.  Its unclear why this 
just started failing...

cc75435ebf Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stack 
adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in
the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If
not, then there is the potential for the stack to be changed while the stack's
being used by another instruction (like a call).

This can only result in tears...

c641c8c6ec Change LowerFP_TO_SINT to create the specific code it needs instead of 
unconditionally creating an i64 bitcast.  With the future legalizer
design, operation legalization can't introduce new nodes with illegal
types.

This fixes the rest of olden on ppc32.

ae3b47b06f When we start enabling SMUL_LOHI/UMUL_LOHI or SDIVREM/UDIVREM in 
target-indepenent lowering, don't use them on PowerPC.

c7b51b678d First round of ppc long double. call/return and 
basic arithmetic works.
Rename RTLIB long double functions to distinguish
different flavors of long double; the lib functions
have different names, alas.

81cfdc2f19 Change getCopyToParts and getCopyFromParts to always use target-endian 
register ordering, for both physical and virtual registers. Update the PPC
target lowering for calls to expect registers for the call result to
already be in target order.

a62327ea40 Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits from 
TargetLowering to SelectionDAG so that they have more convenient
access to the current DAG, in preparation for the ValueType routines
being changed from standalone functions to members of SelectionDAG for
the pre-legalize vector type changes.

681a87d9e8 Starting implementation of the ELF32 ABI specification of varargs handling.

(VAARG, VACOPY and VAEND) are not yet implemented.

5897c064a6 The PPC64 ELF ABI is "intended to use the same structure layout and calling convention rules

e3eae5e265 Fix ixaddrs as well, allowing ppc64 to compile to: 
_test2:
        li r2, 0
        lis r3, 1
        std r2, 9024(r3)
        blr

instead of:

_test2:
        lis r2, 1
        li r3, 0
        ori r2, r2, 9024
        std r3, 0(r2)
        blr

This implements CodeGen/PowerPC/LargeAbsoluteAddr.ll:test2
