4fca01731a Don't print a label for the first MBB in a function.
Compile this:

%_2E_str_8 = external global [75 x sbyte]
implementation   ; Functions:
declare int %printf(sbyte*, ...)
void %test()
        %tmp.101 = call int (sbyte*, ...)* %printf( sbyte* getelementptr ([75 x sbyte]* %_2E_str_8, int 0, int 0) )             ; <int> [#uses=0]
        unreachable
}

to this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        add %l0, %lo(_2E_str_8), %o0
        call printf
        nop

instead of this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        or %g0, %lo(_2E_str_8), %l1   ;; extra instruction
        add %l1, %l0, %o0
        call printf
        nop

b9169ceb23 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.

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.

171049d10f * 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.)

c4769bb529 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]

        call test3
        nop
        restore %g0, %g0, %g0
        retl

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.
