Add support for fmul node of type v4f32.
...
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = mul <4 x float> %tmp1, %tmp1
store <4 x float> %tmp2, <4 x float> *%a
ret void
}
Is selected to:
_foo:
li r2, 0
lvx v0, r2, r3
vxor v1, v1, v1
vmaddfp v0, v0, v0, v1
stvx v0, r2, r3

Add support patterns to many load and store instructions which will
...
hopefully use patterns in the near future.

Represent the encoding of the SPR instructions as they actually are, so
...
that we can use the correct SPR numbers in the InstrInfo.td file. This is
necessary to support VRsave.

Add the remainder of the AltiVec 4 x float instructions. Further
...
enhancements will be necessary to teach the code generator that since
there is no fmul, it will have to do vmaddfp, adding +0.0.

Some first bits of AltiVec stuff: Instruction Formats, Encodings, and
...
Registers. Apologies to Jim if the scheduling info so far isn't accurate.
There's a few more things like VRsave support that need to be finished up
in my local tree before I can commit code that Does The Right Thing for
turning 4 x float into the various altivec packed float instructions.

Added InstrSchedClass to each of the PowerPC Instructions.

Note that when adding new instructions that you should refer to the table at the
bottom of PPCSchedule.td.
