-; This test is based on the following C++ code:
-;
-; void f()
-; {
-;   for (int i=0; i<12; i++) {
-;     try {
-;       if (i==3)
-;         throw i;
-;     } catch (int) {
-;       continue;
-;     } catch (...) { }
-;     if (i==3) break;
-;   }
-; }
-;
-; The loop info analysis identifies the catch pad for the second catch as being
-; outside the loop (because it returns to %for.end) but the associated
-; catchswitch block is identified as being inside the loop.  Because of this
-; analysis, the LCSSA pass wants to create a PHI node in the catchpad block
-; for the catchswitch value, but this is a token, so it can't.
