  24. def findClobbers(l: Global.icodes.Local, bb: Global.icodes.BasicBlock, idx: Int): Unit

    Finds and marks all clobbers of the given local starting in the given basic block at the given index

    Finds and marks all clobbers of the given local starting in the given basic block at the given index

    Storing to local variables of reference or array type may be indirectly observable because it may remove a reference to an object which may allow the object to be gc'd. See SI-5313. In this code I call the LOCAL_STORE(s) that immediately follow a LOCAL_STORE and that store to the same local "clobbers." If a LOCAL_STORE is marked useful then its clobbers must go into the set of clobbers, which will be compensated for later
