+// Bug 1322288 is about the floating join register not being reserved properly
+// in the presence of boolean evaluation for control. The situation is that a
+// conditional branch passes a floating point value to the join point; the join register
+// must be available when it does that, but could have been allocated to the operands of
+// the conditional expression of the control flow.
+//
+// This test is white-box: it depends on the floating join reg being among the first
+// floating registers to be allocated.
