unless you try to div/mod 0 by anything, in which case you will
get some cute number, and not 0, which is bad.

231b11ba87 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.

e009e40008 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.

884def40f4 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!

ec177e242d 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.

d4562971b3 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

2ba4a8584c Add some simple integer patterns. This allows us to compile this: 
int %test(int %A) {
  %B = add int %A, 1
  %C = xor int %B, 123
  ret int %C
}

into this:

test:
        save -96, %sp, %sp
        add %i0, 1, %l0
        xor %l0, 123, %i0
        restore %g0, %g0, %g0
        retl
        nop

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

91e36127ed Use the AsmPrinter for global variable init printing. This eliminates a 
bunch of code and causes V8 to start using the fancy .asciz directive that
the sun assembler supports.
