Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a calculation control method for built-in functions of the Mining language.

[Conventional technology]

In a programming language with built-in functions, we analyzed the processing of Konnoki R4 vectors.

Conventionally, when an intrinsic function that has been determined to be vector-processable cannot be developed into a vector processing instruction of the node, the aforementioned intrinsic function routine exists in the program area.

The control is transferred there along with the parameter, and the
.

The calculations of the vector processing function were controlled by performing all numerical operations and returning the execution results to the quoting side of the function.

[Problem that the invention seeks to solve]

In the conventional method described above, when transferring control to one built-in function routine, a return address is stored, a nomura meter list is created, and control is transferred to the function routine.

Saving/restoring registers used in function routines.

Operations such as receiving and passing the result of a function's operation and returning to the quoting side of the function are required, and processing other than the function's original operation is required.

SUMMARY OF THE INVENTION An object of the present invention is to provide an arithmetic control system for vector processing built-in functions that solves the above-mentioned problems in the prior art.

[Means for solving problems]

The arithmetic control method for vector processing built-in functions according to the present invention provides a means for analyzing the control flow of a program and an analysis of vector processing in a computer system that has built-in functions in a programming language and has vector processing instructions. It has means for optimizing the program, means for optimizing the program, and means for inline expansion of two built-in functions.

〔Example〕

Next, two embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. First, the translation program 1 is the source program 2 that describes the program.
t- manually and convert it into the first intermediate language 3. Next, the translation program 1 is subjected to vector processing by means 4 for analyzing the control flow of the program and means 5 for analyzing the vector processing and converting it into vector processing as a human power of the first intermediate language 3t. into intermediate language 6. moreover,
The translation program 1 converts the second intermediate language 6 into the third intermediate language 8 by means 7 for optimizing the program.

Furthermore, the translation program 1 performs inline expansion processing on the third intermediate language 8 by means 9 for inline expansion of built-in functions, thereby creating a final target program 10t of machine language instructions.

The above embodiment will be explained based on the flow of an actual program. .

In the prior art, as shown in FIGS. 3 and 4.

In the execution of the vector processing intrinsic function, flow 20 creates a meter list required by the intrinsic function, flow 30 stores the return address, and then flow 4 is executed to transfer control to the intrinsic function routine.
0), after saving the registers in flow 50 and importing the nomura meter in flow 60, the function operation is executed in flow 70, the registers are restored in flow 80, and the function value is restored in flow 90. After performing the return process, control was returned to the quoting side of the function.

In the present invention, as shown in FIG. 2, it is only necessary to execute the vector processing built-in function by inline expansion in flow 100.
．． 60, 80, and 90 are no longer necessary, and it is possible to eliminate overhead other than the original calculations of the vector processing built-in function.

〔Effect of the invention〕

As described above, according to the second aspect of the present invention, processing other than the original calculation of the function becomes unnecessary, and the overhead when executing the vector processing built-in function can be reduced.

Also, by performing inline expansion of one built-in function,
This has the effect of expanding the scope of application of Konnoguira's optimization processing and increasing program execution speed.
