             Bug #: 14172
           Summary: Bitcode Reader/Assembler incorrectly  handles structs
                    of arrays in different address space.
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Bitcode Reader
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: micah.villmow at amd.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


; RUN: llvm-as < %s | llvm-dis > %t1.ll
; RUN: diff %s %t1.ll
target datalayout =
"e-p:128:128:128-p1:32:32:32-p2:8:8:8-p3:16:16:16-p4:64:64:64-p5:96:96:96-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:32"

define i64 @fa_1() nounwind {
  %t = ptrtoint { [7 x double], [7 x double] } addrspace(4)* null to i64
  ret i64 %t
}

define { [7 x double], [7 x double] } addrspace(4)* @fa_2() nounwind {
  %t = getelementptr { [7 x double], [7 x double] } addrspace(4)* null, i64 11
  ret { [7 x double], [7 x double] } addrspace(4)* %t
}

define i64 @fa_3() nounwind {
  %t = ptrtoint { [7 x double], [7 x double] } addrspace(4)* getelementptr ({
[7 x double], [7 x double] } addrspace(4)* null, i64 11) to i64
  ret i64 %t
}

define i64 @fa_4() nounwind {
  %t = mul i64 ptrtoint ({ [7 x double], [7 x double] } addrspace(4)*
getelementptr ({ [7 x double], [7 x double] } addrspace(4)* null, i64 11) to
i64), 5
  ret i64 %t
}

define i64 @fa_5() nounwind {
  %t = bitcast i64 mul (i64 3, i64 mul (i64 ptrtoint ({ [7 x double], [7 x
double] } addrspace(4)* getelementptr ({ [7 x double], [7 x double] }
addrspace(4)* null, i64 11) to i64), i64 5)) to i64
  ret i64 %t
}


The above test case fails when being run because fa_4 and fa_5 do not produce
the same code at assembly, the structs { [7 x double], [7 x double] }
addrspace(4) somehow get incorrectly mapped to double*.
