Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] This is a control method for setting the specified value of a translation option function when a so-called compiler system of an information processing system consists of a basic system and an extended system. The basic system sets the so-called default value of the basic system and the specified value of both the basic and extended systems, and then the extended system scans the options of the extended system for which no specified value is set and sets the default value. Set the value. In this way, it is possible to improve the processing efficiency of option value setting while reducing changes to the basic system due to addition of an expansion system.

[Industrial application field]

The present invention relates to a method for controlling the setting of specified values of translation option functions when a so-called compiler system of an information processing system consists of a basic system and an extended system.

As is well known, a translation processing system, a so-called compiler system, consists of a program that translates a program written in a programming language such as FORTRAN into a required format for execution on a computer. Various functions can be specified and selected at the start of translation, such as specifying whether or not to output a program list, various lists related to variables in the program, etc., and specifying the output format, specifying whether or not to incorporate a debugging function, etc. Yes, it is called an optional function.

When a large number of optional functions are provided to accommodate a variety of usage patterns, in order to save the user the trouble of specifying all of them, optional functions for which specification is omitted are provided with a certain predetermined specification. In many cases, a so-called default value setting function is provided.

[Problems that the prior art and invention attempt to explain]

FIG. 3 is a block diagram showing an example of the configuration of an information processing system.

The processing device 1 receives control information, original program information, etc. from the input device 2, inputs it to the storage device 3, and executes the translation processing program of the basic system 4 and expansion system 5 of the compiler system held in the storage device 3. Accordingly, the translation process of the original program is executed according to the input control information, and the result is output to the output device 6.

Here, the compiler basic system 4 is one that translates FORTRAN language and generates a target program to be executed on a normal processing device.
This is a normal compiler system, and the extension system 5 is a system for adding translation functions, etc. necessary for, for example, combining with such a basic system to generate a target program to be executed by a vector processor, for example. It is.

At the start of translation processing, it is necessary to analyze the input option designation information 7 and set designated option values or default values in the option control area 8 of the basic system and the option control area 9 of the extended system.

Option specification information 7 specifies the sequence of required specification information for an optional function that requires a special specification by the user, for example in a format such as "option name" = "specified value". It is specified as a value.

The user specifies only the optional functions that require special specification as option specification information 7, and for the optional functions that do not have a specific specification,
It is planned that default values predefined in this compiler system will be set as designated values for each optional function.

These default values are held in the basic system 4 and expansion system 5 for all options of each system.

First, the basic system 4 sets default values for all the optional functions in the optional control area 8, which is the optional control area of the basic system, in the area allocated to each optional function.

Thereafter, by sequentially scanning the option designation information 7 and analyzing the designation in the above format, for example, a designated value is set in the area of the option function determined by the option name in the option control area 8.

The option specification information 7 can include specification information for the optional function of the basic system and specification information for the optional function of the extended system. If it is determined that it is not, the analysis process for that specified term is stopped and the process proceeds to the next term.

Normally, the use of an extended system is considered to be one of the optional functions, and when a function that can be realized by the extended system is used, it is specified as one item of the option designation information 7.

When the basic system 4 finishes the above-mentioned analysis process, it checks the required area of the option control area 8, identifies whether the use of the extended system is specified, and if so, shifts the execution to the extended system 5.

In order to set the option specification value of the expansion system in the option control area 9, the expansion system 5 sets the default value and the option specification information 7.
Processing such as scanning and setting of specified values through analysis is performed in the same manner as in the basic system 4.

Here, in the extended system 5, as in the case of the basic system 4, it is necessary to scan and analyze all the items in the option designation information 7, and then identify and set only the option designations of the extended system.

FIG. 4 is a diagram explaining the flow of the above processing. When the process is started, the base system 4 sets respective default values for all options of the base system in the option control area 8 in step 10 of the process.

Next, in steps 11 and 12 of the process, one item of the option specification information 7 is analyzed, and if it is an option for the basic system, in step 13, the default value of the corresponding option area of the option control area 8 is rewritten with the specified value. If not a system option, step 13 is bypassed.

In the next step 14, it is determined whether all terms have been scanned, and if not, the process returns to step 11.

In this way, when the loop of steps 11 to 14 is completed for all items in the option specification information 7, it is determined in step 15 whether an expansion system is specified, and if there is a specification, the process moves to the expansion system 5. . If no extended system is specified, the option value setting process ends.

The expansion system 5 sets all default values of the options of the expansion system in the option control area 9 in step 16, and then performs processing steps 17 and 18.
If it is an option for the extended system, the option value is set in the option control area 8 in step 19. If it is not an option for the basic system, step 19 is bypassed, and in step 20, the option value is set in the option control area 8. Determine whether scanning of all terms has been completed, and if not, proceed to step 17.
Return to

That is, according to the above option value setting process,
Loop of steps 11-14 and steps 17-2
As shown in the loop of 0, if there is a specification to use the extended system, all items in the option specification information 7 must be scanned twice, so it takes a relatively long time to set the option value. There was a problem.

[Means for solving problems]

FIG. 1 is a block diagram showing the configuration of the present invention.

The figure shows the configuration of a compiler system in an information processing system, where 24 is a basic system and 25 is an extended system.

[Effect]

In the option value setting process prior to translation processing as in the prior art, the base system 24 first sets a default value in the option control area 8 of the base system as in the prior art.

Next, the option specification information 7 is scanned and analyzed as before, but the specified value of the option of the basic system is set in the option control area 8, and if the option specification information of the extended system is identified, the specified value is It is set in the area of the corresponding option in the option control area 9.

After all the items in the option establishment information 7 have been scanned in this way, if there is a designation to use the extended system, the processing is transferred to the extended system 25.

The expansion system 25 sequentially checks the control area of each option function on the option control area 9 of the options of the expansion system, and if the specified value is set, it is left as is, and if it is not set, the option function is changed. A predetermined default value held within the control area is set for the control area.

By the above processing method, option specification information 7
is scanned and analyzed only once, making it possible to speed up the option value setting process. Furthermore, since each system has a default value, even if the expansion system 25 is added to the basic system later, the amount of change required to the basic system can be kept to a relatively small amount.

〔Example〕

In FIG. 1, a basic system 24 and an expansion system 25 have the same functions as the conventional basic system 4 and expansion system 5 except as described below, and other components are indicated by the same reference numerals in FIG. 3. is the same as the above description.

In the following, the process will be explained with reference to the flowchart of the process shown in FIG. 2 together with FIG. 1.

As before, the basic system 24 performs option value setting processing prior to translation processing.
As in the prior art, a default value is first set in the option control area 8 of the basic system (step 30 of the process in FIG. 2).

Next, in steps 31 and 32, one item of the option designation information 7 is scanned and analyzed in the conventional manner. If it is a specification of an option for the basic system, the specified value is set in the option control area 8 (step 33), and if it is a specification of an option for an extended system, the specified value is set in the area of the corresponding option in the option control area 9. Set the value (step 34).

In step 35, it is determined whether scanning of all terms of the option designation information 7 has been completed, and if there is any unprocessed item, the process returns to step 31.

After repeating the loop of steps 31 to 35 in this way and scanning all the items in the option specification information 7, it is determined in step 36 whether there is a specification to use the expansion system, and if there is a specification, the expansion system 25 processes the option. If there is no specification, the option value setting process ends.

The expansion system 25, in step 37,
Option control area 9 for expanded system options
The control range of the optional function is checked one by one, and if the specified value is set, it is left as is, and if it is not set, the process proceeds to step 38, and the control area is set to the predetermined default value held in itself for that optional function. area.

Whether or not a specified value has been set in a control area can be determined by, for example, providing a valid flag bit in each control area and initially setting it to '0', and then checking the corresponding valid flag bit when the basic system 25 sets the specified value. By setting '1', it can be identified.

In step 39, it is determined whether all items in the option control area 9 have been checked. If there are any items that have not been checked, the process returns to step 37, and when all items have been processed, the option setting process ends.

By the above processing method, option specification information 7
is scanned and analyzed only once, and extended system 2
5 scans only the option control area of the extended system and only needs to set default values for the options, which generally speeds up the option value setting process.

Moreover, since each system has a default value, even if the expansion system 25 is added to the basic system later, the amount of change required to change the functions of the basic system to the basic system 24 is as follows.
The amount can be kept to a relatively small amount.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in a compiler system for an information processing system, option specification values including default values can be set by making a relatively small change in the conventional system.
Since it can be configured to be faster, it has a significant industrial effect of economically improving the processing efficiency of the system.
