           Summary: llvm-upgrade can't do uint %x and int %x together.
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-upgrade
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: patil.nikhil at gmail.com


llvm-upgrade cannot upgrade the following program:

; ModuleID = 'b.c'
target datalayout = "e-p:32:32"
target endian = little
target pointersize = 32
target triple = "i686-pc-linux-gnu"

implementation   ; Functions:

void %main() {
entry:
        %tmp = alloca uint, align 4             ; <uint*> [#uses=1]
        %tmp = alloca int, align 4              ; <int*> [#uses=1]
        "alloca point" = cast int 0 to int              ; <int> [#uses=0]
        store uint 1, uint* %tmp
        store int 2, int* %tmp
        br label %return

return:         ; preds = %entry
        ret void
}

It fails with: Redefinition of value named 'tmp' in the 'i32 *' type plane


(The above program was produced by compiling the following with the llvm-gcc4-
1.9-x86-FC5 binary:
void main()
{
    {
        unsigned int tmp = 1;
    }
    {
        int tmp = 2;
    }
}
