Abstract

This application discloses code processing methods, apparatuses, and storage media. An example method includes: obtaining a first code in low-level language and applicable to a source platform; decompiling the obtained first code to obtain an intermediate representation (IR); and then compiling the IR into a second code in low-level language and applicable to a first target platform, where the source platform and the target platform have different instruction sets.

First claim

1 . A method, wherein the method comprises:
obtaining a first code in low-level language and applicable to a source platform; decompiling the first code to obtain a first intermediate representation (IR); and compiling the first IR into a second code in low-level language and applicable to a first target platform, wherein the source platform and the first target platform have different instruction sets.

2 . The method according to claim 1 , wherein the method further comprises:
decompiling the first code to obtain a second IR corresponding to a second target platform, wherein the first target platform and the second target platform have different instruction sets.

3 . The method according to claim 1 , wherein the method further comprises:
presenting a target platform selection interface; and determining the first target platform from a plurality of target platforms in response to a selection operation on a target platform through the target platform selection interface.

4 . The method according to claim 1 , wherein the decompiling the first code to obtain a first IR comprises:
obtaining annotation information of the first code, wherein the annotation information comprises one or more of a type, a quantity, or a jump address type of a parameter in the first code; and decompiling the first code based on the annotation information, to obtain the first IR.

5 . The method according to claim 1 , wherein the decompiling the first code to obtain a first IR comprises:
decompiling the first code to obtain a second IR; and optimizing the second IR based on the first target platform, to obtain the first IR.

6 . The method according to claim 1 , wherein the method further comprises:
generating prompt information that prompts for a to-be-checked item to be generated based on a difference between the first target platform and the source platform; and presenting the prompt information.

7 . The method according to claim 1 , wherein the method is applied to a cloud, wherein the first code is obtained from a user, and wherein the method further comprises:
sending the second code to the user.

8 . The method according to claim 1 , wherein the decompiling the first code comprises:
decompiling the first code based on an instruction semantic library corresponding to the source platform.

9 . The method according to claim 8 , wherein the method further comprises:
modifying the instruction semantic library in response to a modification operation on the instruction semantic library.

10 . The method according to claim 1 , wherein the obtaining a first code in low-level language and applicable to a source platform comprises:
obtaining the first code in low-level language and applicable to the source platform and a variable in high-level language; and the decompiling the first code comprises: translating the first code into the first IR, wherein the variable is an actual parameter corresponding to a formal parameter in a function of the first IR.

11 . The method according to claim 1 , wherein the first IR comprises a first variable and a second variable, the first variable has a first logical address, the second variable has a second logical address different from the first logical address.

12 . The method according to claim 1 , wherein the decompiling the first code comprises:
decompiling the first code based on a function calling convention or a single instruction multiple data (SIMD) instruction of the first target platform.

13 . A computing apparatus, wherein the computing apparatus comprises at least one memory and at least one processor, the at least one memory is coupled to the at least one processor, and the at least one memory stores programming instructions for execution by the at least one processor to cause the computing apparatus to perform operations comprising:
obtaining a first code in low-level language and applicable to a source platform; decompiling the first code to obtain a first intermediate representation (IR); and compiling the first IR into a second code in low-level language and applicable to a first target platform, wherein the source platform and the first target platform have different instruction sets.

14 . The computing apparatus of claim 13 , wherein the operations further comprise:
decompiling the first code to obtain a second IR corresponding to a second target platform, wherein the first target platform and the second target platform have different instruction sets.

15 . The computing apparatus of claim 13 , wherein the operations further comprise:
presenting a target platform selection interface; and determining the first target platform from a plurality of target platforms in response to a selection operation on a target platform through the target platform selection interface.

16 . The computing apparatus of claim 13 , wherein the decompiling the first code to obtain a first IR comprises:
obtaining annotation information of the first code, wherein the annotation information comprises one or more of a type, a quantity, or a jump address type of a parameter in the first code; and decompiling the first code based on the annotation information, to obtain the first IR.

17 . The computing apparatus of claim 13 , wherein the decompiling the first code to obtain a first IR comprises:
decompiling the first code to obtain a second IR; and optimizing the second IR based on the first target platform, to obtain the first IR.

18 . The computing apparatus of claim 13 , wherein the operations further comprise:
generating prompt information that prompts for a to-be-checked item to be generated based on a difference between the first target platform and the source platform; and presenting the prompt information.

19 . The computing apparatus of claim 13 , wherein the first code is obtained from a user, and wherein
the operations further comprise: sending the second code to the user.

20 . A non-volatility computer-readable storage medium comprising programming instructions for execution by at least one processor of a computing apparatus to cause the computing apparatus to perform operations comprising:
obtaining a first code in low-level language and applicable to a source platform; decompiling the first code to obtain a first intermediate representation (IR); and compiling the first IR into a second code in low-level language and applicable to a first target platform, wherein the source platform and the first target platform have different instruction sets.
