+Subject: [PATCH 54/54] Fix failure with gcc.c-torture/execute/ashrdi-1.c -Os
+ execution test
+
+The following tests fail with -Os option because a shift instruction
+in a branch delay slot gets replaced with multiple instructions when
+the processor has no barrel shifter. This fix addresses the problem
+by marking the responsible instruction pattern as type multi preventing
+it from being placed in a delay slot.
+
+>  gcc.c-torture/execute/ashrdi-1.c   -Os  execution test
+>  gcc.c-torture/execute/pr40057.c   -Os  execution test
+>  gcc.c-torture/execute/pr79121.c   -Os  execution test
+>  gcc.c-torture/execute/pr82524.c   -Os  execution test
+>  c-c++-common/torture/vector-compare-1.c   -Os  execution test
+>  gcc.dg/torture/vec-cvt-1.c   -Os  execution test
+
+These tests pass with this fix.
