test/Regression/Transforms/ConstProp/float-to-ptr-cast.ll is failing. Here's the
error shown:

FAIL:
/home/nicholas/llvm/test/Regression/Transforms/ConstProp/float-to-ptr-cast.ll:
child process exited abnormally
llvm-as: <stdin>:3,0: Reference to an invalid definition: 'cast_upgrade2' of
type 'i64'
opt: Standard Input is empty!
llvm-dis: Standard Input is empty!

It's producing the following output:

define i32* %test1() {
    %cast_upgrade1 = fptoui float 0.0 to i64
    %X.pntr.s1.u0 = inttoptr i64 %cast_upgrade2 to i32*
    ret i32* %X.pntr.s1.u0
}

define i32* %test2() {
    ret i32* inttoptr( i64 fptoui(float 0.0 to i64) to i32*)
}

The bug is undefined %cast_upgrade2 when it should be %cast_upgrade1. This is a
very recent change (today).
