1ffbbc9ebc Use Evan's outflag stuff to implement V8cmpicc. This allows us to write a
pattern for SUBCCrr, and makes it trivial to add support for SUBCCri, eliminating
an instruction in the common "setcc X, imm" case.

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.

d87688fe72 * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

4e8124bd9b implement vastart. The dag isel compiles this:
void test3(va_list Y);
void test2(int F, ...) {
  va_list X;
  va_start(X, F);
  test3(X);
}

into this:

test2:
        save -104, %o6, %o6
        st %i5, [%i6+88]
        st %i4, [%i6+84]
        st %i3, [%i6+80]
        st %i2, [%i6+76]
        st %i1, [%i6+72]
        add %i6, 72, %o0
        st %o0, [%i6+-4]
        call test3
        nop
        restore %g0, %g0, %g0
        retl
        nop

The simple isel emits:

test2:
        save -96, %o6, %o6
        st %i0, [%i6+68]
        st %i1, [%i6+72]
        st %i2, [%i6+76]
        st %i3, [%i6+80]
        st %i4, [%i6+84]
        st %i5, [%i6+88]
        or %g0, 1, %l0
        or %g0, 4, %l1
        umul %l0, %l1, %l0
        add %l0, 7, %l0
        and %l0, -8, %l0
        sub %o6, %l0, %o6
        add %o6, 96, %l0
        add %i6, 72, %l1
        st %l1, [%l0]
        ld [%l0], %o0
        call test3
        nop
        restore %g0, %g0, %g0
        retl
        nop

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.

7a430ddf61 Fix pifft by correcting the case when a i64/f64 straddles O5 and memory:
we were storing into [FP+88] instead of [FP+92].
Improve codegen by emitting [FP+92], instead of emitting a copy of FP into
another GPR which wouldn't be coallesced because FP isn't register allocated.
