9764a3cf09 Implement Transforms/InstCombine/vec_extract_elt.ll, transforming: 
define i32 @test(float %f) {
        %tmp7 = insertelement <4 x float> undef, float %f, i32 0
        %tmp17 = bitcast <4 x float> %tmp7 to <4 x i32>
        %tmp19 = extractelement <4 x i32> %tmp17, i32 0
        ret i32 %tmp19
}

into:

define i32 @test(float %f) {
        %tmp19 = bitcast float %f to i32                ; <i32> [#uses=1]
        ret i32 %tmp19
}

On PPC, this is the difference between:

_test:
        mfspr r2, 256
        oris r3, r2, 8192
        mtspr 256, r3
        stfs f1, -16(r1)
        addi r3, r1, -16
        addi r4, r1, -32
        lvx v2, 0, r3
        stvx v2, 0, r4
        lwz r3, -32(r1)
        mtspr 256, r2
        blr

and:

_test:
        stfs f1, -4(r1)
        nop
        nop
        nop
        lwz r3, -4(r1)

cfa86314dd Changes to fix problems with "make check". Apparently you can redefine 
functions and Tcl's just tickled with that. The fix is to give the "new"
test system a different interface function name.

3553a131d0 Implement InstCombine/vec_demanded_elts.ll:test2. This allows us to turn 
unsigned test(float f) {
 return _mm_cvtsi128_si32( (__m128i) _mm_set_ss( f*f ));
}

into:

_test:
        movss 4(%esp), %xmm0
        mulss %xmm0, %xmm0
        movd %xmm0, %eax
        ret

instead of:

_test:
        movss 4(%esp), %xmm0
        mulss %xmm0, %xmm0
        xorps %xmm1, %xmm1
        movss %xmm0, %xmm1
        movd %xmm1, %eax
        ret

GCC gets:

_test:
        subl    $28, %esp
        movss   32(%esp), %xmm0
        mulss   %xmm0, %xmm0
        xorps   %xmm1, %xmm1
        movss   %xmm0, %xmm1
        movaps  %xmm1, %xmm0
        movd    %xmm0, 12(%esp)
        movl    12(%esp), %eax
        addl    $28, %esp
        ret

798486bc87 For PR1319: 
More improvements:
1. Using ::errorInfo wasn't such a hot idea. Go back to just printing the
   offending line of code and the stderr output. This is sufficient and
   not entangled with Tcl goop.
2. Capture the problem report numbers and report them whether pass or fail.
   This helps quickly get some context when a test fails, if it has an
   associated PR number.

489c9a2006 Add a script to run a command but ignore its return code. This script 
always returns 0. This is useful with the llvm.exp based dejagnu testing
when a test wants to check the error output of tool invocation that
returns non-zero. Since every command is checked with llvm.exp, there needs
to be a way to prevent that checking and this script is it.
