Detailed Description of the Invention

[0001]

Field of the Invention The present invention relates to a link processing method for generating one load module from a plurality of object modules, and more particularly to a link processing method when an unresolved reference external name of an external name occurs.

[0002]

2. Description of the Related Art Conventionally, in a link process for generating a load module, an object module output by a compiler is input and an external name included in the input module is associated with a reference external name and a defined external name. A solution process is performed (see Japanese Patent Laid-Open No. 2-118728). If necessary, the system library or the user's library designated in advance is searched, the object module is input, and the solution processing is performed. As a result, if an unresolved reference external name remains in the end, an error is output and whether the load module is generated depends on the processing system. Recovery processing is not performed for the unresolved reference external name that remains.

[0003]

In the conventional link processing described above, the unresolved reference external name that finally remains is terminated without performing the recovery processing. Except when the unresolved reference external name is intentionally generated by the user, some mistake of the user (for example, a mistake in the reference external name or the definition external name, or a library search designation If it is due to lack, etc., it is necessary to restart link processing at least. In the worst case, the restart of the link process is necessary because the source is modified and the compilation is redone, which has the drawback of requiring man-hours and time.

[0009]

Next, the present invention will be described with reference to the drawings. In FIG. 1 showing the block configuration of the whole link processing, object module input means A01, A05 for inputting an object module, external name definition reference resolution means A02 for associating a reference external name with a definition external name in the object module, Unresolved reference occurrence determination means A03 that determines whether or not there is an unresolved reference external name that remains unresolved, and a defined external name that resolves the unresolved reference external name exists in the library prepared in advance. 6 means from library search means A04 for searching whether or not to execute, and external name definition reference resolution means A06 and load module generation processing
A13 is equivalent to the conventional link processing technology.
In the object module input means A01 to external name definition reference resolution means A06, the object module OM and the object module from the library LIB1 are input and resolution processing for the defined external name and the referenced external name contained in them is performed. Finally, the final unresolved reference occurrence determination means A07 determines whether or not an unresolved reference external name remains, and if there is no unresolved reference external name, a load module is generated in the load module generation processing A13.

If unresolved reference external names remain, the linker option presence / absence determining means A08 confirms whether or not a newly provided linker option (option for instructing to start this recovery processing) is specified. If there is no designation, the process proceeds to step A13. If there is a designation, the unresolved reference / unreferenced definition list display means A09 causes the unresolved reference external name to remain and the definition external name without reference. Display the list of.

Next, the user error judgment inputting means A10 performs a process which is decided depending on whether these remaining unresolved items to the user are due to the user's error or are intentional. Select. If the user selects recovery processing, there are four types of recovery processing (described later) B,
One of C, D and E is selected and activated.

After the recovery processing B / C / D / E is completed, the external name definition reference resolution means A11 performs resolution processing of the defined external name and the reference external name again. As a result, unresolved reference occurrence determination means A
Determined by 12. If an unresolved reference external name has occurred, the display unit A09 is returned to, and a list of the unresolved reference external names and the unreferenced definition external names that have occurred is displayed, and the user is asked whether to perform recovery processing. The process of selecting is repeated.
If all are resolved and no unresolved reference external name remains, the process A13 generates a load module.

"Unresolved reference /
The "unreferenced defined external name correction process B" is a process in the case where a mismatch between the referenced external name and the defined external name occurs due to a user's mistake, and the unresolved referenced external name remains. Correct the external name correctly in the link process.

Unresolved Reference / Unreferenced Definition External Name Correction Processing B
In FIG. 2 showing the block configuration of FIG. 2, first, the reference / definition selection input means B01 for the corrected external name is used to cause the user to select and input the reference / definition external name to be corrected, and then the new external name input means B02. , Allow the user to enter a new external name for the modified external name. Then modify external name /
The new external name stack table generating means B03 stacks the corrected external name and the corresponding new external name in the internal table. The corrected external name selection end determination means B04 causes the user to determine whether or not there is another external name to be corrected, and if so, returns to the selection input means B01 and repeats the processing. If there is no external name to be modified, the reference / definition external name information modification means B05 creates the external name information table for the reference / definition external name expanded on the memory based on the contents of the stack table generated. To fix. This external name information table is a load module generation means described later.
It is used by A13 during link processing, and is a table of management information consisting of all reference addresses / definition addresses, object modules and storage addresses of external name character strings for each external name. ,
Modify the external name that is the title of this table. (Hereinafter, the information in the external name information table is referred to as external name information or reference information / definition information.) After the external name information table is corrected, the reference / definition external name character string correction means B06 indicates the external name information table. Correct the actual external name string.

The "object module correction output process C" which is another one of the recovery processes is a pair with the above-mentioned "unresolved reference / unreferenced definition external name correction process B". Creates an object module that correctly reflects the modified external name during linking, and outputs the created new object module to the file specified by the user.
That is, the external object name on the source program is corrected, and the normal object module is executed without re-compile processing.
Is generated and output to a file. The process C for generating and outputting the modified object module is activated only when the user selects it as an item in addition to the process B.

In FIG. 3 showing the block configuration of the object module correction output process C, first, the object module group information table generating means C01 is a stack table of the correction external name generated in the process B and the external name information table described above. The object modules that contained the modified external name are selected from the above, and further, the object modules information table already stored in the memory (one for each object module input to the linker is generated, A new object module information table is generated for the selected object module based on the position and size of the object module on the file). The generated new object module information table is used later when actually inputting the object module to be modified.

Then, a new object output file name input means C0
2 causes the user to input the file name of the output destination that outputs the modified new object module, and refers to the new object module information table with the modified object module input means C03 to select one object object to be modified. input. As a result of modifying the input module, if the same reference external name and definition external name are mixed in the input object module, the processing of the linker is not required, so the external name information of the reference is extracted from the object module. Must be deleted. Therefore, the existence checking means C04 for the same external name determines whether the reference external name of the same name and the defined external name are mixed, and if they are mixed, the same external name reference information deleting means C05 is used. The reference information is deleted by, and the character string of the reference external name is also deleted by the same reference name character string deleting means C06.

Further, the address correction information correction means C07 corrects the address correction information used in the load module generation means A13. Address correction information is generated at compile time, and a certain variable (definition) is used in the program (reference).
Each such instruction is generated one by one, and includes information (address) where the reference external name and the definition external name are respectively. As a result of modifying the input module, the same reference external name and defined external name are now mixed in the input object module, so the reference external name is the same as that generated by the compiler by the address correction information correction means C07. It is necessary to determine the address of the external name and correct the address correction information. On the other hand, when the definition external name and the reference external name of the same external name do not coexist, the external name correcting means C08 corrects the external name of the object module to be corrected.

When the correction of the object is completed by the means C05 to C07 or the means C08, a new object module is created.
The new object module modified by the output means C10 is output to the file input by the means C02. Next, the correction object end determination means C11 determines whether or not there is still an object object to be corrected by referring to the new object object information table generated by the means C01, and if there is, the means. Return to C03 and repeat the processing. When all the corrections are completed, this processing C is ended.

Next, the "main input object module additional input processing D", which is another one of the recovery processing, changes to the object module which becomes the main input to the linker due to one of the user's mistakes during the link processing. When there is a shortage, the main input object module is added and input, and the link processing is continued to generate a normal load module. still,
The main input does not mean secondary input from the library, but input first to the linker.

First, referring to FIG. 4 showing the block structure of the main input object module additional input processing D, the additional main input file name / additional main input object name input means D01 includes an object module to be additionally added as a main input. Ask the user to enter the name of the existing file and the name of the object module to be input from that file. The additional main input file name / additional main input object name stack table generating means D02 creates and stacks an internal table in which the input file name and the object module name are associated with each other. Additional main input object input end determination means D03
Causes the user to determine whether or not there is another additional main input object module, and if so, returns to the means D01 and repeats the processing. Otherwise, the main input object input information table generating means D04 refers to the internal table generated by the means D02 to generate the main input object input information table. The main input object input information table has the file name containing the object and the main input object name as the main information, and is a table of the same format as that used by the linker for the original object input. The additional object module input means D05 inputs the object module in the same manner as the original main input with reference to this information table.

Next, "library additional search processing E" which is another one of the recovery processing is caused by a mistake made by the user.
This is a process to deal with the case where an unresolved reference external name occurs in the linker due to lack of specification of the library to be searched, specify the library to be searched additionally during link processing, and search for that library to find the required object. Enter the module,
Let the link process continue and generate a normal load module.

In FIG. 5 showing the block configuration of the additional library search process E, first, the additional search library name input means E01 makes the user input the name of the library to be additionally searched. Then, the additional search library name stack table generation means E02 stacks the input library name in the internal table. Additional search library name input end judgment means
E03 causes the user to determine whether or not there is another additional search library, and if so, returns to the means E01 and repeats the processing.

If it is determined that there is no other means, the additional library search information table generating means E04 causes the means E0.
Create an additional library search information table by referring to the internal table created in 2. The generated additional library search information table has the name of the additional search library as the main information, and has the same format as the conventional one used by the linker to perform the original library search. The additional library search means E05 searches the generated search information table, and when an object module including the resolution definition external name exists, the additional object module input means E06 inputs the off-object module. If it does not exist, this recovery processing is ended as it is.

FIG. 6 is a flowchart of the processing contents of the link processing A.

First, the SP01 inputs an object module, and resolves a reference external name of an external name and a defined external name. Next, in SP02, it is determined whether or not an unresolved external reference name has occurred. If not, the process proceeds to SP17 and a load module is generated. If an unresolved referenced external name occurs,
Proceed to SP03 and search for a defined external name that will be resolved in the library. When the resolution-defined external name is found by the search, the process proceeds to SP05 in the determination of SP04, the object module including the resolution-defined external name is input, and the resolution processing of the reference external name and the defined external name is performed. Finally, it is judged in SP06 whether or not the unresolved reference external name remains, and if not, S
Proceed to P17 to create a load module, and if there are any remaining, proceed to SP07. On the other hand, if the definition external name that can be resolved cannot be found in the diary, the process directly proceeds from SP04 to SP07.

In SP07, it is determined whether or not an option (a linker option to be newly provided) instructing to start this recovery processing is designated by the user. If not, the process proceeds to SP17 and the load module is executed. To generate. If specified, a list of unresolved referenced external names and unreferenced defined external names that finally remained in SP08 is displayed on the screen. Next, in SP09, the user is prompted to input whether the displayed unresolved referenced external name and unreferenced defined external name are those intended by the user or those left by mistake. If the user's intention, proceed to SP17 to generate a load module, and if it is a mistake, proceed to SP10, SP11, SP12,
The user is made to select the processing to be activated from the four types of recovery processing of SP13 and SP14. Flow charts of the processes of SP11, SP12, SP13, and SP14 are shown in FIGS. 7 to 10, respectively.

At the stage of the recovery process, a new external object module is input, or a process of changing the reference external name or the definition external name is performed. Therefore, after each recovery process, the SP15 again refers to the external name. And define Resolve external name. Next, in SP16, it is determined whether or not an unresolved external reference name has occurred, and if so, return to SP08 again,
Repeat the process. If there is no unresolved reference external name, proceed to SP17 and generate a load module.

FIG. 7 is a flowchart of the unresolved reference / unreferenced definition name correction processing (SP11), which is one of the recovery processing described above.

First, SP18 allows the user to select an external name to be corrected from the list of unresolved reference / unreferenced definition names displayed on the screen. Then, at SP19, the user is prompted to enter a new external name. In SP20, the corrected external name and the corresponding new external name input in SP19 are stacked in the internal table. Next, at SP21, the user is allowed to select whether or not there is an external name to be further corrected.
Return to and repeat the process. If not, proceed to SP22, SP20
While referring to the stack table generated in step 3, the external name information (table generated in memory) of the referenced external name or the defined external name is actually corrected, and the character string of the external name is corrected in SP23.

FIG. 8 is a flowchart of the object module correction output process (SP12) which is another one of the above-mentioned recovery processes. In addition, this process is SP11
Immediately after the unresolved reference / unreferenced definition name correction process of
SP in addition to SP11 when the user selects recovery processing
Executed when 12 is also selected.

First, the SP24 generates an information table regarding the object module including the external name modified in SP11. As described above, this information table is used when inputting the object module to be actually corrected from the file. Next, at SP25, the user is prompted to input the name of the file to which the corrected object module is to be output, and at SP26, the object module to be actually corrected is input from the file.

Next, in SP27, as a result of the correction of the external name, in the object module currently being corrected,
Checks whether the referenced external name and the defined external name that have the same name coexist. If they are mixed, the process proceeds to SP28, the reference information of the corresponding external name is deleted, the character string of the reference external name is deleted at SP29, and the corresponding address correction information is corrected at SP30. Then SP33
Proceed to and output the modified object module to the specified file.

On the other hand, as a result of the inspection in SP27, if they are not mixed, the process proceeds to SP31, the reference information or definition information of the external name to be corrected is corrected, and the character string of the external name is corrected in SP32. After that, similarly, the program proceeds to SP33, and the corrected object module is output to the specified file. Finally, in SP34, the presence or absence of another object module to be corrected is determined by referring to the information table generated in SP24, and if there is, SP26
The process returns to and the process is repeated. If there is no such process, this recovery process ends.

FIG. 9 is a flowchart of a main input object module additional input process (SP13) which is another one of the above-mentioned recovery processes.

First, at step SP35, the user is prompted to input the name of the file containing the object module to be additionally input and the name of the object module to be input from the file. Next, in SP36, the input file name and the object module name are made to correspond to each other and are stacked in the internal table. Next, let the user select whether or not there is another additional main input object module.
If yes, return to SP35 and repeat the process. If no, SP
Proceed to 38 to generate an input information table for additional input objects. Finally, in SP39, actually input the object module according to the input information table.

FIG. 10 is a flowchart of the library additional search process (SP14) which is the last one of the above-mentioned recovery processes.

[0038] First, the SP40 makes an additional search
The user is made to input the first name, and then, in SP41, the internal name of the library is generated and stacked. Next, in SP42, the user is prompted to enter the presence or absence of the additional search gallery, and if there is, go back to SP40 and repeat the process. If not, go to SP43 and generate an information table for additional search for the diary. To do.
In SP44, referring to the information table, the actual library is searched. The presence or absence of the resolution definition external name in this search is determined by SP45, and if it is present, the process proceeds to SP46, the object module including the resolution definition external name is actually input, and this recovery processing ends. On the other hand, if it does not exist, this recovery processing is ended as it is.

[0039]

As described above, in the link processing of the present invention, if the unresolved reference external name finally remained is the user's mistake, the link processing is not terminated. The recovery process can be performed, and the normal generation of the load module can be efficiently achieved.

When the reference external name and the defined external name are mixed, the same external name reference information deleting means for deleting the reference external name from the object module, and the reference external having the same name mixed in the same object module Name and the above definition of the external name (1) Address correction information correction means for correcting the address correction information for managing the address in one object module, and the uncorrected object when the reference external name and the defined external name of the same name do not coexist in the input corrected object module External name correction means for correcting the corrected external name of the module to the new external name to generate a new object module; new object module output means for outputting the new object module to a predesignated file; and the information table The link processing method at the time of occurrence of an unresolved referenced external name, characterized in that it comprises load module generation means for performing the link processing with reference to the above to generate one load module from the plurality of object modules. 3. An object module input means for inputting an object module in a link processing method when an unresolved reference external name occurs in a link processing system for generating one load module from a plurality of input object modules, An external name definition reference resolution means for associating and resolving a referenced external name and a defined external name in the object module, and an unresolved determination as to whether or not there is an unresolved referenced external name left unresolved in the association. Reference occurrence determining means, library searching means for searching whether or not the defined external name that resolves the unresolved referenced external name exists in a library prepared in advance, and the result of the search by the library searching means is final. A final unresolved reference occurrence determination means for determining whether or not unresolved reference external names remain , List of unresolved references / unreferenced definitions that displays a list of unreferenced definition external names that are definition external names that were unreferenced with the final unresolved reference external name when the final unresolved reference external name remains Display means, additional main input file name / additional main input object name input means for inputting an additional object module name additionally input to the linker and a file name containing the additional object module, and the input file name And an additional main input file name / additional main input object name stack table generating means for stacking the additional object module name with the additional object module name and inputting the additional object module from the file with reference to the internal table. Additional object module input means and the additional object module Linking scheme in unresolved external reference name when generating characterized in that they are composed of the load module generation means for generating a single load module from the plurality of object modules, including Le. 4. An object module input means for inputting an object module in a link processing method when an unresolved reference external name occurs in a link processing system for generating one load module from a plurality of input object modules, An external name definition reference resolution means for associating and resolving a referenced external name and a defined external name in the object module, and an unresolved determination as to whether or not there is an unresolved referenced external name left unresolved in the association. Reference occurrence determining means, library searching means for searching whether or not the defined external name that resolves the unresolved referenced external name exists in a library prepared in advance, and the result of the search by the library searching means is final. A final unresolved reference occurrence determination means for determining whether or not unresolved reference external names remain , List of unresolved references / unreferenced definitions that displays a list of unreferenced definition external names that are definition external names that were unreferenced with the final unresolved reference external name when the final unresolved reference external name remains Display means, additional search library name input means for inputting an additional library name for additional search, additional search library name stack table generating means for generating an internal table stacking the input additional library name, and the internal Additional library search means for searching the additional library with reference to a table, and additional object module input means for inputting an additional object module including the solution definition external name when the solution definition external name exists in the additional library And the plurality of object modules including the additional object module Linking scheme in unresolved external reference name when generating characterized in that they are composed of the load module generation means for generating et single load module.
