Named for Tantalus (a legendary king of Lydia condemned to stand in a pool of water up to his chin and beneath fruit-laden boughs only to have the water or fruit recede at each attempt to drink or eat), she was the only U.S. Naval vessel to bear the name. Originally laid down as "LST-1117" on 10 October 1944 at Seneca, Illinois by the Chicago Bridge and Iron Company; launched on 2 January 1945; sponsored
Unreachable code of the values of variables and other conditions at run time. In some languages (e.g. Java ) some forms of unreachable code are explicitly disallowed. The optimization that removes unreachable code is known as dead code elimination. Code may become "unreachable" as a consequence of the internal transformations performed by an optimizing compiler (e.g., common subexpression elimination). In practice the sophistication of the analysis performed has a significant impact on the amount of unreachable code that is detected. For example, constant folding and simple flow analysis shows that the inside of the if-statement in the following code is "unreachable": However,
