Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
At present, an instruction generated by a just-in-time compiler lacks debugging information such as a file name, a line number and the like, and a jump instruction without stack information may be used in a running process of a just-in-time compiler generation program (program for short), for example, a return address is not pushed like a function call instruction when a relative or absolute jump instruction is used after a function is linked in, that is, a program running track cannot be obtained from the stack information. After the program fails to run, only one entry can be found by the experience of a program debugger, and the program is subjected to single-step debugging to determine the error position when the program runs. Obviously, when the existing just-in-time compiler generates a program and runs in error, the error position of the program is difficult to determine, and the debugging efficiency of the program is reduced.
One of the core concepts of the embodiment of the invention is that at the compiling stage of generating a program by an instant compiler, corresponding compiler calling information is recorded aiming at a jump instruction in the program; and recording corresponding execution flow information when the jump instruction runs, and further generating debugging information of the program according to compiler calling information and execution flow information so as to conveniently locate the error position when the program fails to run and improve the debugging efficiency of the program.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a processing method of a program according to the present invention is shown, and specifically may include the following steps:
step 101, in the compiling process of the program, recording corresponding compiler calling information according to a jump instruction compiled in the program.
The program in the embodiment of the invention refers to a just-in-time compiler generating program, and can be used for generating a just-in-time compiler. In the compiling process of the program, namely in the compiling stage of the just-in-time compiler generating program, the corresponding compiler call information can be recorded aiming at the jump instruction compiled in the just-in-time compiler generating program. The compiler calling information may be used to determine a calling relationship between calling functions corresponding to the jump instruction, for example, may include identification information of the calling functions. The identification information may be a unique identification of the calling function, for example, a random number that is not repeated and is automatically generated by the program, which is not limited in this embodiment of the present invention.
And 102, recording corresponding execution stream information in the process of executing the jump instruction, wherein the execution stream information is used for determining the running track of the jump instruction.
In a specific implementation, when a jump instruction in an instant compiler generation program runs, the jump instruction may be recorded to generate execution stream information of the jump instruction. The execution flow information may be used to determine an execution trajectory of the jump instruction. For example, in the program running process, a memory location where a pointer of the jump instruction is located in the running stage may be recorded for the jump instruction, and then execution stream information corresponding to the jump instruction may be formed based on the recorded memory location.
Step 103, generating debugging information of the program according to the compiler calling information and the execution flow information.
In the embodiment of the invention, the corresponding relation between the calling information of the compiler and the execution stream information can be established aiming at the jump instruction in the program, and then the corresponding debugging information can be generated based on the corresponding relation. The debug information may be used to determine the trace of the program, such as the jump instruction that may be executed several times last by the program and where and how the jump instruction was generated by the JIT compiler, which is not limited by the present invention.
To sum up, in the program compiling stage, according to the jump instruction compiled in the program, the embodiment of the present invention may record the corresponding compiler call information, and may record the corresponding execution flow information when the jump instruction runs, so as to generate the debugging information of the program according to the compiler call information and the execution flow information, where the debugging information may be used to determine the running track of the program, and further may locate the program error position based on the debugging information when the program fails to run, that is, the error position when the program fails to run is conveniently located, and the debugging efficiency of the program is improved.
In order that those skilled in the art will better understand the embodiments of the present invention, the following description is given with reference to the examples.
As an application example of the present invention, an additional function may be added to a function for generating a jump instruction for a just-in-time compiler in advance in a just-in-time compiler generating program, where the additional function includes: a) saving the file name and line number of the current function and the parameter information such as the function call stack of the current just-in-time compiler when the just-in-time compiler generates a jump instruction, and recording the compiler call information based on the saved parameter information; b) when the jump instruction generated by the instant compiler runs, the PC recording the jump instruction and the corresponding relation between the PC and the compiler calling information recorded in the a) are recorded.
Therefore, the execution flow information can be generated based on the recorded PC, the debugging information of the program can be generated based on the corresponding relation, and the program error position can be positioned based on the debugging information when the program operation fails, so that the error reason of the program can be conveniently found, and the debugging efficiency is improved.
It should be noted that the just-in-time compiler generator may include one or more functions, and the functions may include one or more instructions, etc. In this example, the function of the just-in-time compiler that generates the jump instruction may be used to generate the jump instruction, and the function of the just-in-time compiler that generates the jump instruction may contain or call one or more other functions; the PC may be used to characterize the memory location at which the jump instruction is executed.
In addition, a memory area can be opened up, and when the JIT compiler generation program runs, compiler calling information related to jump instructions compiled by the JIT compiler generation program and execution flow information corresponding to all executed jump instructions can be recorded. It should be noted that the size of the compiler call information recorded in the memory area may be fixed, for example, may be a fixed value, and the implementation of the present invention is not limited thereto. The recorded execution flow information may be used to determine a jump instruction execution trajectory, which may grow with program execution time. Alternatively, in order to prevent the memory shortage, the memory size for recording the execution flow information may be set by the user, and when the memory is full, the jump instruction execution trajectory may be overwritten from the head.
In an optional embodiment of the invention, the method may further comprise: setting a memory area according to preset distribution information, wherein the memory area is used for storing data information, and the data information comprises at least one of the following: the compiler calling information, the execution flow information and the debugging information; and outputting based on the data information in the memory area after the program fails to run.
In this embodiment of the present invention, the preset allocation information may be used to allocate a memory size of the memory area, and optionally, may be set by a user, which is not limited in this embodiment of the present invention.
Specifically, in the running stage of the instant compiler generating program, the execution flow information of the jump instruction and the corresponding relationship between the execution flow information and the compiler calling information may be written into the memory area. Therefore, after the program fails to run, the data information recorded in the memory area can be output so as to conveniently locate the position of the program error, for example, jump instructions executed for a plurality of times recently and the position and the generation of the jump instructions in the program generated by the JIT compiler can be determined, and the cause of the program running error can be found. The number of the most recently executed instructions of the jump instruction may be determined according to the size of the memory area, which is not limited in the embodiment of the present invention.
Optionally, if the error position cannot be found, if the calling hierarchy is found to be insufficient, the program may be rerun by increasing the memory area, so as to trace back more jump instructions forward to locate the error position of the program.
Referring to fig. 2, a flowchart illustrating steps of an alternative embodiment of a processing method of a program according to the present invention is shown, and specifically may include the following steps:
step 201, setting a memory area according to preset allocation information, wherein the memory area is used for storing data information.
Wherein the data information comprises at least one of: the compiler call information, the execution flow information, and the debug information.
Specifically, the memory area set in the embodiment of the present invention may include one or more areas, for example, the memory area may include a first area for storing compiler call information, a second area for storing execution flow information, and an association area, and the embodiment of the present invention is not limited thereto. The association area may be used to store a corresponding relationship between the compiler call information and the execution flow information, for example, may be used to store a corresponding relationship between the compiler call information and the execution flow information.
Step 202, recording corresponding compiler calling information according to a jump instruction compiled in a program.
Specifically, compiler call information corresponding to the jump instruction at the compiling stage may be recorded in the memory area, for example, in the process of generating the program compiling jump instruction by the just-in-time compiler, parameter information such as a file name, a line number, and a function call stack of the current just-in-time compiler may be acquired for the jump instruction, and the parameter information may be recorded, and compiler call information may be generated based on the recorded parameter information.
In an alternative embodiment of the present invention, the step 202 may include the following sub-steps:
substep 2021, when compiling the jump instruction, generating a function call instruction corresponding to the jump instruction, where a function parameter called by the function call instruction includes identification information of the jump instruction.
And a substep 2022 of obtaining compiler calling information corresponding to the jump instruction according to the identification information.
As an example of the present invention, in the compilation process of the JIT compiler-generated program, when a jump instruction is generated, a function call instruction may be generated at the same time to record compiler call information corresponding to the jump instruction by the function call instruction. The function parameter called by the function call instruction may be identification information of the jump instruction.
For example, the function call instruction may be a callFuncToSave function called in the jump instruction generation function genCallOrJump (). The callfuncttosave function can be used for storing the PC of the jump instruction into the second area of the memory according to the identification information of the jump instruction when the program runs, that is, storing the PC of the jump instruction into the memory area set in the step 201, and if the memory is found to be full, covering the original data; and the PC of the jump instruction may be associated with the identification information, so as to write the correspondence between the compiler call information and the execution stream information into the association area of the memory allocated in step 201.
Specifically, for each jump instruction in the program, the just-in-time compiler generating program may create a corresponding jump instruction generating function genCallOrJump (); the jump instruction generation function genCallOrJump () may store, based on a preset data structure struct debuglinfo, the corresponding troubleshooting information debuglinfo when the jump instruction is generated, as compiler call information in the embodiment of the present invention. For example, the jump instruction generating function genCallOrJump () may be configured to determine whether a program debugging function is activated, and when the program debugging function is activated, create a new data structure for the jump instruction, so as to record the debug information debugginfo corresponding to the jump instruction based on the newly created data structure.
Optionally, the troubleshooting information debuggelnfo may include: identification information, file name file, line number line, current instruction information, current function call information, and the like, which are not limited in this embodiment of the present invention.
The identification information can be a unique identification Id of each target jump instruction, and the target jump instruction can be used for representing a currently executed or compiled jump instruction in a program; the file name file can be used for representing the file where the current called function is located; the line number line can be used for representing the line number of the currently called function, for example, the number of lines of the currently called function in a file can be determined; the current instruction information can be a current PC (personal computer), and the PC can be used for representing the memory position of the current instruction; the current function call information may be used to determine a parent function corresponding to the current function, and may include: a pointer to the newly created data structure debugginfo for the jump instruction. Wherein, the pointer of the debugginfo pointing to the structure body can be identified as debugginfo parent.
In an optional example, the file name file and the line number line of the parent function called by the current function can be obtained according to symbol table information of the PC and the program; based on the same mode, the parent function of the parent function can be obtained, and by analogy, the debugginfo of the function call chain can be obtained by backtracking according to the mode. It should be noted that the depth of the backtracking stack may be specified by a user, and the embodiment of the present invention is not limited thereto.
For example, a program may start executing the function func1(), on line 10 of the file a.c; and function func1() called function func2a () on line 11 of file a.c and function func2b () on line 18 of file a.c; and function func2b () was executed starting at line 50 of file a.c and called function func3() at line 51 of file a.c.
Function func3() may start executing on line 10 of another file b.c and may call function func4() on line 11 of file b.c; this function func4() may start executing at line 21 of the file b.c and may call the function generateCallOrJump () at line 22; and may start executing at line 30 of the file b.c at the jump instruction generating function genCallOrJump (), which may generate a jump instruction __ j (target) at line 31 of the file b.c.
Based on the files a.c and b.c, when the program finally generates the jump instruction __ j (target), possible call relations include:
case 1) func1 → func2a → func3 → func4 → genCallOrJump; or,
case 2) func1 → func2b → func3 → func4 → genCallOrJump.
If the case 1 is adopted, a debug info linked list can be generated based on the calling relationship among the functions in the case 1, as shown in the following table 1:
TABLE 1
In this example, the parent function of the function func1 is not traced, so its parent is null.
In the example, association can be established through the parent field in the data structure struct DBUGInfo of each function and the Id of the parent function, so that a DebugInfo linked list is formed. The debugginfo linked list can be used for storing information of how a jump instruction is generated by a just-in-time compiler code, so that the information in the debugginfo linked list can be used as compiler calling information in the embodiment of the invention.
Optionally, for the same function call relationship, a record may be stored, for example, if the backtracking depth specified by the user is 4, if the parent function parent called when the backtracking depth is 2 is the same, and the parent function called when the backtracking depth is 3 is the same, and the parent function of the parent function called when the backtracking depth is 4 is also the same, the record may be regarded as the same call stack information, and a corresponding record may be stored in the debugginfo linked list, which is not specifically limited in this embodiment of the present invention.
Step 203, recording corresponding execution stream information in the process of executing the jump instruction.
In the embodiment of the present invention, optionally, when executing each jump instruction in the program, the memory location where each jump instruction is currently located is respectively obtained; according to the memory location, recording corresponding execution stream information, for example, the execution stream information may be stored in the memory area as data information in the memory area.
As an example of the present invention, in combination with the above example, in the running process, if the program fails to run after executing the jump instruction generating function genCallOrJump () three times, and the PCs executing the jump instruction generating function genCallOrJump () three times are 0x10000100, 0x10000200, and 0x10000300, respectively, the recorded execution flow information for the jump instruction may be: 0x10000100, 0x10000200, 0x 100003000.
The execution flow information recorded in the program execution stage may vary with the length of the program execution time and the size of the number of jump instructions experienced. When the memory is full, the data originally recorded in the memory area may be overwritten, for example, the execution flow information recorded before may be overwritten, so as to record the jump instruction executed recently.
And 204, generating corresponding debugging information according to the compiler calling information and the execution flow information.
In an alternative embodiment of the present invention, the step 204 may include the following sub-steps:
substep 2041, determining a correspondence between the compiler calling information and the execution flow information based on the identification information;
and a substep 2042 of generating corresponding debugging information based on the correspondence, wherein the debugging information is used for determining the error position when the program fails to run.
Specifically, the PC of the jump instruction may be associated with the identification information, thereby determining a correspondence between the execution stream information and the compiler call information; and the corresponding relation can be stored in the memory area, so that a corresponding relation table of the PC of the jump instruction and the ID in the compiler calling information can be formed and used as debugging information of the program. For example, after the program executes the jump instruction generation function genCallOrJump () three times, the identification information debuglinfo.id of the jump instruction __ j (target) generated three times may be 0x 000005. Further, a corresponding relationship table may be formed according to a corresponding relationship between the identification information debugginfo.id of the jump instruction __ j (target) and the memory location PC where the jump instruction is generated three times by the program, as shown in table 2 below:
TABLE 2
In step 205, after the program fails to run, the program is output based on the data information in the memory area.
In the embodiment of the present invention, after the program fails to run, the program may be output based on the data information recorded in the memory area, for example, the compiler call information recorded in the memory area may be output. The outputted compiler call information can be used for positioning the program operation error position, such as the execution flow information of all jump instructions several times before the program failure and the compiler call information generated by the JIT compiler when the program is compiled, etc.
As an example of the present invention, after the program fails to run, the data information in the memory area may be printed out. Specifically, complete symbol information may be obtained based on the compiler calling information determined in step 203 and the execution flow information determined in step 204, such as the information in the debugginfo linked list and the PC information in the correspondence table, and the symbol information may be used as data information to be printed. For example, in connection with the above example, after three generation instruction failures are experienced, the printed data information may be as shown in table 3 below:
TABLE 3
Based on the information in table 3, it can be determined that the program jumps from 0x10000100 to 0x10000200, and executes an error after continuously jumping to 0x 10000300; the jump instruction of 0x10000300 is generated from line 30 in the b.c file, and the function of line 30 in the b.c file is … … called from line 21 in the file, so that the error position in the source code can be located quickly, and then the error cause of the program operation can be further determined according to the context of the error position.
