Generating compiled code that indicates register liveness |
摘要 |
<p>Object code is generated from an internal representation that includes a plurality of source operands. The generating includes performing for each source operand in the internal representation determining whether a last use has occurred for the source operand. The determining includes accessing a data flow graph to determine whether all uses of a live range have been emitted. If it is determined that a last use has occurred for the source operand, an architected resource associated with the source operand is marked for last-use indication. A last-use indication is then generated for the architected resource. Instructions and the last-use indications are emitted into the object code.</p> |
