            Bug ID: 21497
           Summary: miscompilation after SVN r220256
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org
          Reporter: compnerd at compnerd.org
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Slightly reduced test case:

// RUN: %clang -fPIC -target i686-windows-itanium -c %s

extern int a();
extern int b();
extern int c();
extern int d();

int test(long long ll, void *pv) {
  int result = 1;
  switch (ll) {
  case 1:
    result = a();
    break;
  case 2:
    result = c();
    break;
  case 3:
    result = d();
    break;
  case 4:
    if (pv == 0) {
      (void)d();
      result = b();
    } else {
    }
    break;
  }
  return (result);
}

Setting SetDirectiveSuppressesReloc to true corrects the issue.
