fb5b11046b If a target doesn't have HasMULHU or HasUMUL_LOHI, ExpandOp would return 
without lo/hi set.  Fall through to making a libcall instead.

2b4c279a8e Add a simple optimization to simplify the input to 
truncate and truncstore instructions, based on the 
knowledge that they don't demand the top bits.

8266952813 Codegen support for vector intrinsics. 
Factor out the code that expands the "nasty scalar code" for unrolling
vectors into a separate routine, teach it how to handle mixed
vector/scalar operands, as seen in powi, and use it for several operators,
including sin, cos, powi, and pow.

Add support in SplitVectorOp for fpow, fpowi and for several unary
operators.

just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

525178cdbf Migrate X86 and ARM from using X86ISD::{,I}DIV and ARMISD::MULHILO{U,S} to 
use ISD::{S,U}DIVREM and ISD::{S,U}MUL_HIO. Move the lowering code
associated with these operators into target-independent in LegalizeDAG.cpp
and TargetLowering.cpp.

ccf596a53e convertFromInteger, as originally written, expected sign-extended 
input.  APInt unfortunately zero-extends signed integers, so Dale
modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.

different flavors of long double; the lib functions
have different names, alas.

910993e8dc Change APFloat::convertFromInteger to take the incoming 
bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.

to prevent surprising match when called with const
argument.

9e3d3abd93 Remove the assumption that FP's are either float or 
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).
