摘要： Assigns suitable registers to a plurality of variables. A compiler converts a source program into instructions for a processor having: a simultaneously used variable acquisition section which obtains, with respect to each of a plurality of variables used in the source program, some of the other variables used simultaneously with the variable; an allocation sequence generation section which generates a plurality of allocation sequences between the plurality of variables to allocate each variable to one of the plurality of registers different from those to which some of the other variables used simultaneously with the variable are allocated; an allocation priority acquisition section which obtains allocation priorities indicating to which one of the plurality of registers each variable is allocated with priority; and a register allocation section which allocates the variables to registers in accordance with an allocation sequence selected on the basis of the allocation priorities.

摘要： A compiler includes a register allocator for allocating registers for instructions in a program to be compiled, and a code generator for generating object code based on the register allocation results performed by the register allocator. The register allocator allocates logical registers for instructions in the program to be compiled. The register allocation further allocates, to physical registers, the logical registers that are allocated to the instructions of the program, so that the physical registers that are live at a procedure call in the program to be compiled are allocated from the bottom of the register stack.

摘要： In order to improve the efficiency of execution of a program by prefetching data necessary to execute the program, a system is provided that causes a computer to execute a recursive query prior to a program being subjected to prefetching. This system detects from iterative processing in the program a query to generate a resultant table by selecting a record that satisfies a selection condition from a target table. The system generates an initial query to generate an initial table that includes values of variables that are set prior to starting the iterative processing in the program. Furthermore, the system generates a recursive query to generate the next intermediate table that is referred to in the next and later cycles of the iterative processing, in the recursive query corresponding to each cycle of the iterative processing that is sequentially performed, from an intermediate table that includes resultant tables generated by a target query in the preceding cycles of the iterative processing and the target table. Furthermore, the system generates a final query to generate a final table from the intermediate table sequentially generated by the recursive query.

摘要： A method for processing a multidimensional array object in which a multidimensional array is implemented by an array of array objects. The multidimensional array object comprises array objects which constitute the multidimensional array. Flags representing that it is possible to optimize a process for elements of the multidimensional array object are added as additional information. The flags are stored in a storage device (main memory for instance). Then, a machine code corresponding to a state of the flags is executed.
