7ab65934a0 The X86 instruction selector already handles codegen of: 
store float 123.45, float* %P

as an integer store.  This adds handling of float immediate stores as integers
for arguments passed function calls.

This is now tested by CodeGen/X86/store-fp-constant.ll

18ad19488d Allow the selection-dag based selector to be diabled with -disable-pattern-isel. 
For now, this is the default, as the current selector is missing some big pieces.
To enable the new selector, pass -disable-pattern-isel=false to llc or lli.

5384b38ccc 1. If a double FP constant must be put into a constant pool, but it can be 
precisely represented as a float, put it into the constant pool as a
   float.
2. Use the cbw/cwd/cdq instructions instead of an explicit SAR for signed
   division.

35e5c7c186 This hunk:

Fixes the PPC regressions from last night.

The other hunk is just a clarity improvement.

6dec0b09d5 Fix a FIXME: Select instructions on longs were miscompiled. 
While we're at it, improve codegen of select instructions.  For this
testcase:

int %test(bool %C, int %A, int %B) {
  %D = select bool %C, int %A, int %B
  ret int %D
}

We used to generate this code:

_test:
        cmpwi cr0, r3, 0
        bne .LBB_test_2 ;
.LBB_test_1:    ;
        b .LBB_test_3   ;
.LBB_test_2:    ;
        or r5, r4, r4
.LBB_test_3:    ;
        or r3, r5, r5
        blr

Now we emit:

_test:
        cmpwi cr0, r3, 0
        bne .LBB_test_2 ;
.LBB_test_1:    ;
        or r4, r5, r5
.LBB_test_2:    ;
        or r3, r4, r4
        blr

e7f96c515e Substantially improve the code generated by non-folded setcc instructions. 
In particular, instead of compiling this:

bool %test(int %A, int %B) {
  %C = setlt int %A, %B
  ret bool %C
}

to this:

test:
        save %sp, -96, %sp
        subcc %i0, %i1, %g0
        bl .LBBtest_1   !
        nop
        ba .LBBtest_2   !
        nop
.LBBtest_1:     !
        or %g0, 1, %i0
        ba .LBBtest_3   !
        nop
.LBBtest_2:     !
        or %g0, 0, %i0
        ba .LBBtest_3   !
        nop
.LBBtest_3:     !
        restore %g0, %g0, %g0
        retl
        nop

We now compile it to this:

test:
        save %sp, -96, %sp
        subcc %i0, %i1, %g0
        or %g0, 1, %i0
        bl .LBBtest_2   !
        nop
.LBBtest_1:     !
        or %g0, %g0, %i0
.LBBtest_2:     !
        restore %g0, %g0, %g0
        retl
        nop

c0354c904b Set the rounding mode for the X86 FPU to 64-bits instead of 80-bits. We 
don't support long double anyway, and this gives us FP results closer to
other targets.

This also speeds up 179.art from 41.4s to 18.32s, by eliminating a problem
with extra precision that causes an FP == comparison to fail (leading to
extra loop iterations).

56c5d7369b Bools are *also* not ints. Sigh. Furthermore, most of the TargetMachine 
ctor parameters can be defaulted.

Print the transformed llvm code input to the instruction selector
when -print-machineinstrs is on, just like V9.

4f70b63ebc Make GEPs not suck so much: 
* Don't emit the Index * ElementSize multiply if Index is a constant.
* Use a shift, not a multiply, if ElementSize is 1/2/4/8.
* If ElementSize fits in the immediate field of SMUL, then put it there.

Fix a bug where struct offsets might be truncated (ConstantSInt::get is
now used instead of ConstantInt::get).

0284628e8e Fix several bugs in 'op x, imm' handling. Foremost is that we now emit 
addi r3, r3, -1
instead of
   addi r3, r3, 1

for 'sub int X, 1'.

Secondarily, this fixes several cases where we could crash given an unsigned
constant.  And fixes a couple of minor missed optimization cases, such as
xor X, ~0U -> not X

928b47ae2e Revamp long/ulong comparisons to use a much more efficient sequence (thanks 
to Brian and the Sun compiler for pointing out that the obvious works :)

This also enables folding all long comparisons into setcc and branch
instructions: before we could only do == and !=

For example, for:
void test(unsigned long long A, unsigned long long B) {
   if (A < B) foo();
 }

We now generate:

test:
        subl $4, %esp
        movl %esi, (%esp)
        movl 8(%esp), %eax
        movl 12(%esp), %ecx
        movl 16(%esp), %edx
        movl 20(%esp), %esi
        subl %edx, %eax
        sbbl %esi, %ecx
        jae .LBBtest_2  # UnifiedReturnBlock
.LBBtest_1:     # then
        call foo
        movl (%esp), %esi
        addl $4, %esp
        ret
.LBBtest_2:     # UnifiedReturnBlock
        movl (%esp), %esi
        addl $4, %esp
        ret

Instead of:

test:
        subl $12, %esp
        movl %esi, 8(%esp)
        movl %ebx, 4(%esp)
        movl 16(%esp), %eax
        movl 20(%esp), %ecx
        movl 24(%esp), %edx
        movl 28(%esp), %esi
        cmpl %edx, %eax
        setb %al
        cmpl %esi, %ecx
        setb %bl
        cmove %ax, %bx
        testb %bl, %bl
        je .LBBtest_2   # UnifiedReturnBlock
.LBBtest_1:     # then
        call foo
        movl 4(%esp), %ebx
        movl 8(%esp), %esi
        addl $12, %esp
        ret
.LBBtest_2:     # UnifiedReturnBlock

d4c8bea47f Enable optimization suggested by Chris Lattner to not emit reloc stubs for 
static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.

b752a97ca4 There is not a 1-1 mappign between llvm blocks and PPC blocks, do not use 
LLVM blocks as the keys for the branch rewriter.  This fixes treeadd and
many other programs with the JIT.

5efb75daed * Rename existing relocations to be more specific 
* Add relocations for refernces to non-lazy darwin stubs and implement
  them correctly.

With this change, we can correctly references external globals, and now
all but two UnitTests and all but 1 Regression/C tests pass.

More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)

fb887e010d Force the intregs ptr into R2 and the FPregs ptr into R3. This fixes a really 
obscure problem where we were doing:

lmw     r3,0(r9)

which is undefined on PPC.  Now we do:

lmw     r3,0(r2)

by force, not relying on the GCC register allocator for luck :)

the constant pool yet).
