Using identifiers and counters for controlled optimization compilation

摘要: The invention enables a compiler (during its first compilation pass) to insert identifiers during an early optimization phase into machine-independent code. are used for identifying specific instructions of the may use table record assignment and their corresponding portion During subsequent phases pass, portions code transformed machine-dependent code, inherits identification associated with that were generate After executable is made interact test data statistical execution which collected by previously inserted counters. counter consolidated so it relates second pass compiler, reads or captured data, indication association between (which can be stored in table). Subsequently, begins locating relative other pass.
