In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments of the present application are described in detail below with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Referring to fig. 1, an embodiment of the present application provides a hybrid precompilation method, and in a first embodiment of the hybrid precompilation method, the hybrid precompilation method includes:
step S10, acquiring a program file to be precompiled, and performing lexical analysis on the program file to be precompiled to obtain program keywords;
step S20, classifying each program keyword to obtain a keyword classification result;
step S30, dividing the program file to be pre-compiled into an interpretation type program file content and a compilation type program file content according to the keyword classification result;
step S40, generating an interpreted pre-compiling program file corresponding to the program file to be pre-compiled according to the content of the interpreted program file, wherein the interpreted pre-compiling program file is used for inputting into an interpreted compiler for compiling; and generating a compiled pre-compiled program file corresponding to the program file to be pre-compiled according to the content of the compiled program file, wherein the compiled pre-compiled program file is used for being input into a compiled compiler for compiling.
In this embodiment, it should be noted that, when compiling a computer program, usually a text language compiling is required by using a compiler or an interpreter, and before the text language compiling, usually a text language precompiling is required, but only a single compiler or a single interpreter can be precompiled currently, and if the interpreter and the interpreter exist in the computer program at the same time, the precompiling efficiency of the computer program is affected.
The content of the interpreted program file at least includes an interpreted program instruction, for example, the interpreted program instruction may be a program instruction such as MC _ Power or MC _ Stop; the compiled program file content includes at least one of a compiled program instruction, a compiled function, and a program variable, such as a compiled program instruction of I F, and the compiled function may be a compiled function of FC, such as a program variable of BOOL.
As one example, steps S10 to S40 include: extracting a program file to be precompiled from a program file set to be precompiled; extracting each program key word in the program file to be precompiled by performing lexical analysis on the program file to be precompiled; classifying the program keywords according to the parts of speech and the context corresponding to the program keywords to obtain a keyword classification result; according to the keyword classification result, deleting the annotation content in the program file to be precompiled, and determining the content of an interpretation type program file and the content of a compilation type program file in the program file to be precompiled after the annotation content is deleted; pre-compiling the content of the interpreted program file, converting all program instructions in the content of the interpreted program file into corresponding interpreted pre-compiled program instructions, and integrating all the interpreted pre-compiled program instructions into an interpreted pre-compiled program file, wherein the interpreted pre-compiled program file is used for being input into an interpreted compiler for compiling; and pre-compiling the content of the compiled program file, converting all program instructions in the content of the compiled program file into corresponding compiled pre-compiled program instructions, and integrating all the compiled pre-compiled program instructions into a compiled pre-compiled program file, wherein the compiled pre-compiled program file is used for being input into a compiled compiler for compiling.

step S42, generating the interpreted precompiled program file by expanding the third precompiled program instruction into the interpreted precompiled program generated by the main program of the to-be-precompiled program file.
In this embodiment, it should be noted that the second predetermined program instruction mapping relationship is a mapping relationship between an interpreter program instruction and an interpreter precompiled program instruction, where the interpreter precompiled program instruction is a program instruction that has the same semantics as a corresponding interpreter program instruction after being precompiled, and the precompiling process is to convert the interpreter program instruction into a corresponding interpreter precompiled program instruction.
As one example, steps S41 to S42 include: inquiring the interpreted pre-compiling program instruction corresponding to each interpreted program instruction as a third pre-compiling program instruction according to the second preset program instruction mapping relation; and according to the semantic sequence corresponding to the original semantic of the interpreted program instruction corresponding to each third pre-compiled program instruction, unfolding each third pre-compiled program instruction into the interpreted pre-compiled program generated by the main program of the program file to be pre-compiled to obtain the interpreted pre-compiled program file.
As an example, it should be noted that different operating systems usually have different precompilation requirements for each interpreter instruction, for example, some operating systems may not need to precompile some specific interpreter instructions, and at this time, these specific interpreter instructions need to be deleted, while some operating systems need to add some additional interpreter instructions on the basis of the original interpreter instructions for precompilation together.
The step of querying the interpreted precompiled program instruction corresponding to each interpreted program instruction as a third precompiled program instruction according to the second preset program instruction mapping relationship includes:
according to the type of the current operating system and the type of the current operating system, adding and deleting the interpretation type program instructions to obtain the added and deleted interpretation type program instructions; and inquiring the interpreted pre-compiling program instruction corresponding to each added and deleted interpreted program instruction as a third pre-compiling program instruction according to the second preset program instruction mapping relation. To meet the pre-compilation requirements for interpreted program instructions in different operating systems.
Before the step of determining the content of the interpreted program file and the content of the compiled program file in the program file to be precompiled according to the keyword classification result, the hybrid precompilation method further includes:
step A10, determining annotation content in the program file to be precompiled according to the keyword classification result;
and step A20, deleting the annotation content in the program file to be precompiled.
As an example, the steps a10 to a20 include: determining annotation keywords in the program keywords according to the keyword classification result; determining annotation content in the program file to be precompiled according to the annotation key; and deleting the annotation content in the program file to be precompiled.
The embodiment of the application provides a hybrid pre-compiling method, namely, firstly, a program file to be pre-compiled is obtained, lexical analysis is carried out on the program file to be pre-compiled to obtain program keywords, and therefore the program keywords are classified to obtain a keyword classification result; determining the content of an interpreted program file and the content of a compiled program file in the program file to be precompiled according to the keyword classification result, namely determining which part of the program file to be precompiled belongs to an interpreted program and which part inputs the compiled program, and generating the interpreted precompiled program file corresponding to the program file to be precompiled according to the content of the interpreted program file, wherein the interpreted precompiled program file is used for being input into an interpreted compiler for compiling; according to the content of the complied program file, generating a complied pre-compiled program file corresponding to the program file to be pre-compiled, wherein the complied pre-compiled program file is used for being input into a complied compiler for compiling, so that the program pre-compiling for an interpreted compiler and the program pre-compiling for the complied compiler can be simultaneously carried out in one pre-compiling process, namely the hybrid compiling of the complied program and the interpreted program is realized, the technical defect that the efficiency of the pre-compiling of the computer program is influenced because only a single complied program or a single interpreted program can be pre-compiled in the traditional pre-compiling process of a text language is overcome, and the efficiency of the pre-compiling of the computer program is improved.
Example two
Further, referring to fig. 2, in another embodiment of the present application, the same or similar contents as those in the above embodiment may refer to the above description, and are not repeated herein. On this basis, the content of the complied program file at least comprises a complied program instruction, and the step of generating the complied pre-compiled program file corresponding to the program file to be pre-compiled according to the content of the complied program file comprises the following steps:
step B10, determining a first pre-compiled program instruction corresponding to the compiled program instruction according to a first preset program instruction mapping relation;
and step B20, generating the compiled type pre-compiled program file according to the first pre-compiled program instruction.
In this embodiment, it should be noted that the first predetermined program instruction mapping relationship is a mapping relationship between a compiler type program instruction and a compiler type pre-compiler program instruction, where the compiler type pre-compiler program instruction is a program instruction that has the same semantic as a corresponding compiler type program instruction after being pre-compiled, and the pre-compiling process is to convert the compiler type program instruction into the corresponding compiler type pre-compiler program instruction.
As an example, the steps B10 to B20 include: inquiring a compiled pre-compiled program instruction corresponding to each compiled program instruction as a first pre-compiled program instruction according to the first preset program instruction mapping relation; and according to the semantic sequence corresponding to the original semantic of the compiler program instruction corresponding to each first pre-compiler program instruction, unfolding each first pre-compiler program instruction into a compiler pre-compiler program generated by the main program of the program file to be pre-compiled to obtain the compiler pre-compiler program file.
Wherein the content of the compiled program file at least comprises a compiled function, and the step of generating the compiled pre-compiled program file according to the first pre-compiled program instruction comprises:
step B21, searching a source program file called by the compiled function in a program file set corresponding to the program file to be precompiled;
step B22, expanding the source program file to a function calling position corresponding to the compiled function for mixed pre-compiling to obtain a second pre-compiling program instruction;
and step B23, generating the compiled type pre-compiled program file according to the first pre-compiled program instruction and the second pre-compiled program instruction.
In this embodiment, it should be noted that, in the present invention, when performing pre-compilation, since a single compiler-type program or a single interpreter-type program is pre-compiled, therefore, once the compiler type function has interpreted program files, the precompilation can not be continued, so that the precompilation can be normally carried out, at present, before the precompilation is usually carried out, a user needs to declare the inclusion relationship among all the program files to be precompiled in a program file set in advance, then after each program file to be precompiled is respectively completed, according to the declared inclusion relation, integrating the result of each program file to be precompiled to obtain the final precompiled result, therefore, the existing precompilation method needs to declare the inclusion relationship among the program files to be precompiled, and greatly influences the precompilation efficiency of the computer program.
As an example, the steps B21 to B23 include: searching a source program file called by the compiled function in a program file set corresponding to the program file to be precompiled; expanding the source program file to a function calling position of the compiling function on the program file to be precompiled to obtain an expanded program file to be precompiled; performing mixed pre-compiling on the expanded program file to be pre-compiled to obtain a second pre-compiled program instruction; according to the semantic sequence of the original semantics of the compiler type program instructions corresponding to the first pre-compiler program instructions and the semantic sequence of the original semantics of the compiler type program instructions corresponding to the second pre-compiler program instructions, expanding the first pre-compiler program instructions and the second pre-compiler program instructions into a compiler type pre-compiler program generated by a main program of the program file to be pre-compiled, and obtaining the compiler type pre-compiler program file. The specific implementation process of performing hybrid pre-compilation on the expanded program file to be pre-compiled to obtain the second pre-compiled program instruction may refer to the specific implementation contents in steps S10 to S40, which are not described herein again. Therefore, the embodiment of the application realizes automatic analysis of the inclusion relationship between different program files to be precompiled, and directly and automatically integrates and compiles the program files to be precompiled with the inclusion relationship in the compiling process in a mixed precompilation mode, so that the inclusion relationship between the different program files to be precompiled is not required to be declared in advance before precompilation, and the precompilation efficiency of the computer program is improved.
As an example, the contents of the compiler file at least include a compiler function, and step S40 includes:
searching a source program file called by the compiled function in a program file set corresponding to the program file to be precompiled; expanding the source program file to a function calling position corresponding to the compiled function for mixed pre-compiling to obtain a pre-compiled program instruction; and generating the compiled type pre-compiled program file according to the pre-compiled program instruction. When the contents of the complied program file at least include a complied function, the specific implementation process of step S40 can refer to the specific implementation contents of steps B21 to B23, which are not described herein again.
Wherein the content of the compiled program file at least includes a program variable, and the step of generating the compiled pre-compiled program file according to the first pre-compiled program instruction and the second pre-compiled program instruction includes:
step C10, performing corresponding custom variable processing on the program variable according to the variable type corresponding to the program variable to obtain a processed program variable;
and step C20, generating the compiled type pre-compiled program file according to the first pre-compiled program instruction, the second pre-compiled program instruction and the processed program variable.
In this embodiment, it should be noted that some variable processes may be customized during hybrid precompilation, so that corresponding customized variable processes may be performed on program variables obtained through analysis, where the customized variable processes may be variable type conversion, for example, the variable types may be converted from integer to long integer.
As an example, the steps B10 to B20 include: determining a corresponding user-defined variable processing mode according to the variable type corresponding to the program variable; according to the determined custom variable processing mode, carrying out corresponding custom variable processing on the program variable to obtain a processed program variable; and integrating the first pre-compiled program instruction, the second pre-compiled program instruction and the processed program variable into a compiled pre-compiled program file according to the original semantic sequence of the program instruction to be pre-compiled in the program file to be pre-compiled, which corresponds to the first pre-compiled program instruction, the second pre-compiled program instruction and the processed program variable respectively.
Wherein the step of generating the compiled pre-compiled program file according to the first pre-compiled program instruction, the second pre-compiled program instruction and the processed program variable includes:
step D10, integrating the first pre-compiled program instruction, the second pre-compiled program instruction and the processed program variable into a main program file according to the original semantics of the first pre-compiled program instruction, the second pre-compiled program instruction and the processed program variable in the program file to be pre-compiled;
step D20, carrying out semantic check on the main program file to obtain a semantic check result;
and D30, if the semantic checking result is correct, using the main program file as the compiled pre-compiled program file.
As an example, the steps D10 to D30 include: sequentially unfolding the first pre-compiling program instruction, the second pre-compiling program instruction and the processed program variable into a compiling type pre-compiling program generated by a main program of the program file to be pre-compiled according to the original semantic sequence of the program instruction to be pre-compiled in the program file to be pre-compiled, which respectively corresponds to the first pre-compiling program instruction, the second pre-compiling program instruction and the processed program variable, so as to obtain a main program file; performing semantic check on the main program file to obtain a semantic check result; if the semantic checking result is correct, taking the main program file as the compiled pre-compiled program file; and if the semantic inspection result is wrong, alarming. The semantic checking mode at least comprises one of compiled instruction syntax checking, function call format checking, type matching checking of assignment operation, paired statement quantity checking, function loop call checking, structural body loop inclusion checking and array subscript overrun checking, wherein the compiled instruction syntax checking is used for checking whether a main program file conforms to preset text language syntax, for example, whether the main program file conforms to C language syntax and the like; the function call format check is used for checking whether the function call format is legal, such as whether redundant commas exist in a function call program instruction; the type matching check of the assignment operation is used for checking whether the assigned variables are consistent with the data types of the corresponding specific assignments or not; the function loop call check is used for checking whether function loop calls have dead loops; the structure circulation comprises checking whether the structure circulation is reasonable; the array index overrun check is used to check whether the number of values in the read array exceeds the index number of values.
