             Bug #: 13960
           Summary: .ll format drops type information on alloca alignment
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Core LLVM classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nicholas at mxc.ca
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


I watched instcombine do something fascinating:

  IC: Mod =   %i = alloca [5 x i8], align 4
  IC: New =   %i = alloca [5 x i8], align 4

Uh oh. Turns out the old '4' was 'i32 4' and the new one is 'i64 4'.
