6892f28e99 SSE does not support i64 SINT_TO_FP (FP stack doesn't either, but we custom 
expand it), so ask legalizer to expand i32 UINT_TO_FP.

362071d7d4 use proper (82-bit) spills/fills when spilling FP regs, so that 
divides don't get broken. this fixes obsequi, smg2000, and probably
a bunch of other stuff (tm)

76bb6ae211 fixing divides: FP should now be 100%, and integers are fine too 
unless you try to div/mod 0 by anything, in which case you will
get some cute number, and not 0, which is bad.

99cf50937d Silly Sparc is big endian. If we have to load args out of incoming stack slots 
that are smaller than an int, make sure to adjust the frame pointer to take
this into consideration.

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)

2b4ea795a2 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

into this:

64aa0ea4e9 this is a hack, which may or may not hang around. In short: 
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?

58fe459e36 Rewrite FP stackifier support in the X86InstrInfo.td file, splitting patterns 
that were overloaded to work before and after the stackifier runs.  With the
new clean world, it is possible to write patterns for these instructions: woo!

This also adds a few simple patterns here and there, though there are a lot
still missing.  These should be easy to add though. :)

See the comments under "Floating Point Stack Support" for more details on
the new world order.

This patch as absolutely no effect on the generated code, woo!

b077b842b6 * Added lowering hook for external weak global address. It inserts a load 
for Darwin.
* Added lowering hook for ISD::RET. It inserts CopyToRegs for the return
  value (or store / fld / copy to ST(0) for floating point value). This
  eliminate the need to write C++ code to handle RET with variable number
  of operands.

85e42b45ac Reserve G1 for frame offset stuff and use it to handle large stack frames. 
For example, instead of emitting this:

test:
        save -40112, %o6, %o6   ;; imm too large
        add %i6, -40016, %o0    ;; imm too large
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

emit this:

test:
        sethi 4194264, %g1
        or %g1, 848, %g1
        save %o6, %g1, %o6
        sethi 4194264, %g1
        add %g1, %i6, %g1
        add %i1, 944, %o0
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

which doesn't cause the assembler to barf.

88276b887c Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows 
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register.  This also requires some asm printer work
to satisfy the darwin assembler.

For
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = add <4 x float> %tmp1, %tmp1
  store <4 x float> %tmp2, <4 x float> *%a
  ret void
}

We now produce:
_foo:
        lvx v0, 0, r3
        vaddfp v0, v0, v0
        stvx v0, 0, r3
        blr

Instead of:
_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

another GPR which wouldn't be coallesced because FP isn't register allocated.

one for use with extload, one for use with sextload and zextload, which
are integer only.

e1389ad43a Teach the addressing mode stuff to fold "%lo" into 'ri' addressing modes, 
allowing us to compile this:

to this:

%G1 = external global int
%G2 = external global int
void %test() {
        %X = load int* %G1
        store int %X, int* %G2
        ret void
}

test:
        save -96, %sp, %sp
        sethi %hi(G1), %l0
        ld [%l0+%lo(G1)], %l0
        sethi %hi(G2), %l1
        st %l0, [%l1+%lo(G2)]
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

test:
        save -96, %sp, %sp
        sethi %hi(G1), %l0
        or %g0, %lo(G1), %l1

long %test(ubyte, short, long %X, long %Y) {
  %A = xor long %X, -1

  ret long %B
}

to this:

test:

        andn %i4, %i2, %i0
        andn %i5, %i3, %i1

        retl

instead of this:

        xor %i2, -1, %l0
        xor %i3, -1, %l1

for example.  I guess it would make sense to add reg/reg versions too.

a07da92624 Use the new predicate support that Evan Cheng added to remove some code 
from the DAGToDAG cpp file.  This adds pattern support for vector and
scalar fma, which passes test/Regression/CodeGen/PowerPC/fma.ll, and
does the right thing in the presence of -disable-excess-fp-precision.

Allows us to match:
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = mul <4 x float> %tmp1, %tmp1
  %tmp3 = add <4 x float> %tmp2, %tmp1
  store <4 x float> %tmp3, <4 x float> *%a
  ret void
}

As:

_foo:
        li r2, 0
        lvx v0, r2, r3
        vmaddfp v0, v0, v0, v0
        stvx v0, r2, r3
        blr

Or, with llc -disable-excess-fp-precision,

_foo:
        li r2, 0
        lvx v0, r2, r3
        vxor v1, v1, v1
        vmaddfp v1, v0, v0, v1
        vaddfp v0, v1, v0
        stvx v0, r2, r3
        blr

cbd6ed4d6b For ISD::RET, if # of operands >= 2, try selection the real data dep. operand 
first before the chain.
e.g.
int X;

int foo(int x)
{
  x += X + 37;
  return x;
}

If chain operand is selected first, we would generate:
	movl X, %eax
	movl 4(%esp), %ecx
	leal 37(%ecx,%eax), %eax

rather than
	movl $37, %eax
	addl 4(%esp), %eax
	addl X, %eax

which does not require %ecx. (Due to ADD32rm not matching.)

4172b10ca1 Use new PPC-specific nodes to represent shifts which require the 6-bit 
amount handling that PPC provides.  These are generated by the lowering code
and prevents the dag combiner from assuming (rightfully) that the shifts
don't only look at 5 bits.  This fixes a miscompilation of crafty with
the new front-end.

3d36a9f6f4 Several things: 
1. Remove redundant type casts now that PR673 is implemented.
2. Implement the OUT*ir instructions correctly.  The port number really
   *is* a 16-bit value, but the patterns should only match if the number
   is 0-255.  Update the patterns so they now match.
3. Fix patterns for shifts to reflect that the shift amount is always an
   i8, not an i16 as they were believed to be before.  This previous fib
   stopped working when we started knowing that CL has type i8.
4. Change use of i16i8imm in SH*ri patterns to all be imm.
