           Summary: "opt -inline -gvn" != "opt -inline" + "opt -gvn"
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Scalar Optimizations
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rafael.espindola at gmail.com
                CC: llvmbugs at cs.uiuc.edu

With the attached testcase, running

$ opt -inline -gvn -o test-final1.ll test.ll
produces different results than
$ opt -inline -o test-temp.ll test.ll
$ opt -gvn -o test-final2.ll test-temp.ll

This is a reduction of a clang bootstrap failure on ARM.
