摘要： In some implementations, the operations of a software system may include the execution of untrusted device drivers. The execution of an untrusted device driver may be initiated when an untrusted device driver that is a set of executable instructions is obtained. A computing resource for the execution of the device driver may be further determined from a device-driver manifest of the untrusted device driver. Computing resources may include one or more of a hardware resource, a memory, an input/output port, an interrupt request line, and an inter-process communication channel. Trusted local access objects may be used by the untrusted device driver to access the computing resources.

摘要： A compact set of garbage collection tables takes advantage of the redundancies often inherent in live pointer information: multiple call sites in a call stack often share common live pointer information. A call site table lists call site identifiers associated with call stack locations having pointers to heap-allocated data. An associated indirection table (i.e., a descriptor reference table) provides a reference (e.g., an index or a pointer) into a descriptor table, which stores unique descriptors of the call stack locations of interest. The aggregate memory space used by the three tables (i.e., the call site table, the indirection table, and the descriptor table) is typically less than the memory space used by the monolithic live pointer information table.

摘要： A method, system, and apparatus for inserting spill code optimized for a complex instruction set computing (CISC) two-address machine, such as a machine utilizing an 80x86 processor is described. The spill code is generated in a single pass. Copy propagation and dead-code elimination are performed to remove unnecessary loads and stores from the stack. Instructions contained within the code block are processed in reverse order. Temporary variables are not extended to the point that they may become spilled by a register allocation procedure. A store to a stack location is inserted if the stack location is not dead, saving the use of a register. Memory operands are substituted when possible in place of load and store instructions on CISC machines.

摘要： Inserting spill code optimized for a complex instruction set computing (CISC) two-address machine. The spill code is generated in a single pass. Copy propagation and dead-code elimination are performed to remove unnecessary loads and stores from the stack. Memory operands are substituted in place of load and store instructions on CISC machines. The number of occurrences of a temporary variable is checked before a load is inserted into the new instructions and before a temporary variable is removed from use. If the variable has only occurred once then the memory operand of the temporary is used in place of the load of the temporary variable saving a load instruction. If the temporary variable is about to be removed from use and the temporary variable has only occurred one time then the variable is not stored saving a store instruction within the spill code.
