492c2935be Implement the LOADABLE_MODULE option when building a shared library. This
passes the -module option on the libtool command line to ensure that the
shared library being built can be dlopened and dlsym can work on that
module. LOADABLE_MODULE should be sent only in conjunction with the
SHARED_LIBRARY directive. It should generally be used for any module that
is intended to be the target of an LLVM -load option. Note that loadable
modules will not have the lib prefix but otherwise look like shared
libraries. This is per the libtool recommendations and prevents these
special shared libraries from being linked in via -l option to the linker.

ef7ba0756b Be more careful where we set ContainsFPCode. We were missing a set in the
int -> FP casting code.  Note that we don't have to set it for FP operations
that take FP values as operands: whatever produces the FP value will set the
flag.

1133309e57 Take register pressure into account when we have to decide whether to
evaluate the LHS or the RHS of an operation first.  This causes good things
to happen.  For example, instead of compiling a loop to this:

.LBBstrength_result7_1: # loopentry
        movl 16(%esp), %edi
        movl (%edi), %edi             ;;; LOAD
        movl (%ecx), %ebx
        movl $2, (%eax,%ebx,4)
        movl (%edx), %ebx
        movl %esi, %ebp
        addl $21, %ebp
        addl $42, %esi
        cmpl $0, %edi                 ;;; USE
        cmovne %esi, %ebp
        cmpl %ebp, %ebx
        movl %ebp, %esi
        jg .LBBstrength_result7_1

We now compile it to this:

.LBBstrength_result7_1: # loopentry
        movl %edi, %ebx
        addl $42, %ebx
        addl $21, %edi
        movl (%ecx), %ebp              ;; LOAD
        cmpl $0, %ebp                  ;; USE
        cmovne %ebx, %edi
        movl (%edx), %ebx
        movl $2, (%eax,%ebx,4)
        movl (%esi), %ebx
        cmpl %edi, %ebx
        jg .LBBstrength_result7_1

Which reduces register pressure enough (in this case) to avoid spilling in the
loop.

As another example, consider the CodeGen/X86/regpressure.ll testcase.  We
used to generate this code for both cases:

regpressure1:
        subl $32, %esp
        movl %esi, 12(%esp)
        movl %edi, 8(%esp)
        movl %ebx, 4(%esp)
        movl %ebp, (%esp)
        movl 36(%esp), %ecx
        movl (%ecx), %eax
        movl 4(%ecx), %edx
        movl %edx, 24(%esp)
        movl 8(%ecx), %edx
        movl %edx, 16(%esp)
        movl 12(%ecx), %edx
        movl 16(%ecx), %esi
        movl 20(%ecx), %edi
        movl 24(%ecx), %ebx
        movl %ebx, 28(%esp)
        movl 28(%ecx), %ebx
        movl 32(%ecx), %ebp
        movl %ebp, 20(%esp)
        movl 36(%ecx), %ecx
        imull 24(%esp), %eax
        imull 16(%esp), %eax
        imull %edx, %eax
        imull %esi, %eax
        imull %edi, %eax
        imull 28(%esp), %eax
        imull %ebx, %eax
        imull 20(%esp), %eax
        imull %ecx, %eax
        movl (%esp), %ebp
        movl 4(%esp), %ebx
        movl 8(%esp), %edi
        movl 12(%esp), %esi
        addl $32, %esp
        ret

This code is basically trying to do all of the loads first, then execute all
of the multiplies.  Because we run out of registers, lots of spill code happens.
We now generate this code for both cases:

regpressure1:
        movl 4(%esp), %ecx
        movl (%ecx), %eax
        movl 4(%ecx), %edx
        imull %edx, %eax
        movl 8(%ecx), %edx
        imull %edx, %eax
        movl 12(%ecx), %edx
        imull %edx, %eax
        movl 16(%ecx), %edx
        imull %edx, %eax
        movl 20(%ecx), %edx
        imull %edx, %eax
        movl 24(%ecx), %edx
        imull %edx, %eax
        movl 28(%ecx), %edx
        imull %edx, %eax
        movl 32(%ecx), %edx
        imull %edx, %eax
        movl 36(%ecx), %ecx
        imull %ecx, %eax
        ret

which is much nicer (when we fold loads into the muls it will be even better).
The old instruction selector used to produce the good code for regpressure1
but not for regpressure2, as it depended on the order of operations in the
LLVM code.

61b8c9bf94 The pattern isel is aggressively codegen'ing all of the loads in these
functions together at the start of the basic block, causing massive spillage.
The old isel codegened the loads wherever they happened to land, so it
generated good code for the first case, but bad code for the second.

We really want the pattern isel to generate (the same) good code for both.

68dc310942 Implement a couple of more simplifications. This lets us codegen:
int test2(int * P, int* Q, int A, int B) {
        return P+A == P;
}

into:

test2:
        movl 4(%esp), %eax
        movl 12(%esp), %eax
        shll $2, %eax
        cmpl $0, %eax
        sete %al
        movzbl %al, %eax
        ret

instead of:

test2:
        movl 4(%esp), %eax
        movl 12(%esp), %ecx
        leal (%eax,%ecx,4), %ecx
        cmpl %eax, %ecx
        sete %al
        movzbl %al, %eax
        ret

ICC is producing worse code:

test2:
        movl      4(%esp), %eax                                 #8.5
        movl      12(%esp), %edx                                #8.5
        lea       (%edx,%edx), %ecx                             #9.9
        addl      %ecx, %ecx                                    #9.9
        addl      %eax, %ecx                                    #9.9
        cmpl      %eax, %ecx                                    #9.16
        movl      $0, %eax                                      #9.16
        sete      %al                                           #9.16

as is GCC (looks like our old code):

test2:
        movl    4(%esp), %edx
        movl    12(%esp), %eax
        leal    (%edx,%eax,4), %ecx

bccc8abc79 Rename Unix/*.cpp and Win32/*.cpp to have a *.inc suffix so that the silly
gdb debugger doesn't get confused on which file it is reading (the one in
lib/System or the one in lib/System/{Win32,Unix})

5cdcc58d51 Add some folds for == and != comparisons. This allows us to
codegen this loop in stepanov:

no_exit.i:              ; preds = %entry, %no_exit.i, %then.i, %_Z5checkd.exit
        %i.0.0 = phi int [ 0, %entry ], [ %i.0.0, %no_exit.i ], [ %inc.0, %_Z5checkd.exit ], [ %inc.012, %then.i ]              ; <int> [#uses=3]
        %indvar = phi uint [ %indvar.next, %no_exit.i ], [ 0, %entry ], [ 0, %then.i ], [ 0, %_Z5checkd.exit ]          ; <uint> [#uses=3]
        %result_addr.i.0 = phi double [ %tmp.4.i.i, %no_exit.i ], [ 0.000000e+00, %entry ], [ 0.000000e+00, %then.i ], [ 0.000000e+00, %_Z5checkd.exit ]          ; <double> [#uses=1]

        %first_addr.0.i.2 = getelementptr [2000 x double]* %data, int 0, uint %indvar           ; <double*> [#uses=1]
        %inc.i.rec = add int %first_addr.0.i.2.rec, 1           ; <int> [#uses=1]
        %inc.i = getelementptr [2000 x double]* %data, int 0, int %inc.i.rec            ; <double*> [#uses=1]
        %tmp.3.i.i = load double* %first_addr.0.i.2             ; <double> [#uses=1]
        %tmp.4.i.i = add double %result_addr.i.0, %tmp.3.i.i            ; <double> [#uses=2]
        %tmp.2.i = seteq double* %inc.i, getelementptr ([2000 x double]* %data, int 0, int 2000)                ; <bool> [#uses=1]
        %indvar.next = add uint %indvar, 1              ; <uint> [#uses=1]
        br bool %tmp.2.i, label %_Z10accumulateIPddET0_T_S2_S1_.exit, label %no_exit.i

To this:

.LBB_Z4testIPddEvT_S1_T0__1:    # no_exit.i
        fldl data(,%eax,8)
        fldl 16(%esp)

bd9f0eefb2 Codegen (Reg|imm)+&GV as an LEA, because we cannot put it into the immediate field
of an ADDri (due to current restrictions on MachineOperand :( ).  This allows
us to generate:

        leal Data+16000, %edx

instead of:

        movl $Data, %edx
        addl $16000, %edx

abd2182875 Add a simple transformation. This allows us to compile one of the inner
loops in stepanov to this:

.LBB_Z5test0PdS__2:     # no_exit.1
        fldl data(,%eax,8)
        fldl 24(%esp)
        faddp %st(1)
        fstl 24(%esp)
        incl %eax
        cmpl $2000, %eax
        fstpl 16(%esp)
        #FP_REG_KILL
        jl .LBB_Z5test0PdS__2

instead of this:

.LBB_Z5test0PdS__2:     # no_exit.1
        fldl data(,%eax,8)
        fldl 24(%esp)
        faddp %st(1)
        fstl 24(%esp)
        incl %eax
        movl $data, %ecx
        movl %ecx, %edx
        addl $16000, %edx
        subl %ecx, %edx
        movl %edx, %ecx
        sarl $2, %ecx
        shrl $29, %ecx
        addl %ecx, %edx
        sarl $3, %edx
        cmpl %edx, %eax
        fstpl 16(%esp)
        #FP_REG_KILL
        jl .LBB_Z5test0PdS__2

The old instruction selector produced:

.LBB_Z5test0PdS__2:     # no_exit.1
        fldl 24(%esp)
        faddl data(,%eax,8)
        fstl 24(%esp)
        movl %eax, %ecx
        incl %ecx
        incl %eax
        leal data+16000, %edx
        movl $data, %edi
        subl %edi, %edx
        movl %edx, %edi
        sarl $2, %edi
        shrl $29, %edi
        addl %edi, %edx
        sarl $3, %edx
        cmpl %edx, %ecx
        fstpl 16(%esp)
        #FP_REG_KILL
        jl .LBB_Z5test0PdS__2   # no_exit.1

Which is even worse!
