F:              ; preds = %0
        ret void
}

to this:

X:

        subcc %i0, 122, %l0
        bg .LBBX_2      ! F

3772bcb333 Revamp the ICC/FCC reading instructions to be parameterized in terms of the 
SPARC condition codes, not in terms of the DAG condcodes.  This allows us to
write nice clean patterns for cmovs/branches.

9072c05cd8 Compile: 
uint %test(uint %X) {
        %Y = call uint %llvm.ctpop.i32(uint %X)
        ret uint %Y
}

to:

test:
        save -96, %o6, %o6
        sll %i0, 0, %l0
        popc %l0, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of to 40 logical ops.  Note the shift-by-zero that clears the top
part of the 64-bit V9 register.

Testcase here: CodeGen/SparcV8/ctpop.ll

76afdc9a80 First step towards V9 instructions in the V8 backend, two conditional move 
patterns.  This allows emission of this code:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        move %icc, %i0, %i2
        or %g0, %i2, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        be .LBBt1_2     !
        nop
.LBBt1_1:       !
        or %g0, %i2, %i0
.LBBt1_2:       !
        restore %g0, %g0, %g0
        retl
        nop

for this:

int %t1(int %a, int %b, int %c) {
        %tmp.2 = seteq int %a, %b
        %tmp3 = select bool %tmp.2, int %a, int %c
        ret int %tmp3
}

2. unless -enable-sparc-v9-insts is passed, disable V9 (for use with llcbeta)

dea9528f7f When lowering SELECT_CC, see if the input is a lowered SETCC. If so, fold 
the two operations together.  This allows us to compile this:

void %two(int %a, int* %b) {
        %tmp.2 = seteq int %a, 0
        %tmp.0.0 = select bool %tmp.2, int 10, int 20
        store int %tmp.0.0, int* %b
        ret void
}

into:

two:
        save -96, %o6, %o6
        or %g0, 20, %l0
        or %g0, 10, %l1
        subcc %i0, 0, %l2
        be .LBBtwo_2    ! entry
        nop
.LBBtwo_1:      ! entry
        or %g0, %l0, %l1
.LBBtwo_2:      ! entry
        st %l1, [%i1]
        restore %g0, %g0, %g0
        retl
        nop

instead of:

two:
        save -96, %o6, %o6
        sethi 0, %l0
        or %g0, 1, %l1
        or %g0, 20, %l2
        or %g0, 10, %l3
        subcc %i0, 0, %l4
        be .LBBtwo_2    ! entry
        nop
.LBBtwo_1:      ! entry
        or %g0, %l0, %l1

        bne .LBBtwo_4   ! entry

.LBBtwo_3:      ! entry
        or %g0, %l2, %l3

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.)

into this:

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.

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
        ld [%l1+%l0], %l0
        sethi %hi(G2), %l1
        or %g0, %lo(G2), %l2

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

to this:

test:
        save -96, %sp, %sp
        andn %i4, %i2, %i0
        andn %i5, %i3, %i1
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

test:
        save -96, %sp, %sp
        xor %i2, -1, %l0
        xor %i3, -1, %l1

        and %i5, %l1, %i1
        restore %g0, %g0, %g0

  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.
