摘要： A method and system for code generation and inlining. The method includes: scanning a code, where the code includes a method; determining whether the method includes a branch if the method is too large in size to be inlined, where the branch is based on runtime types of argument; profiling runtime types of actual arguments at a call site in the method if the method includes the branch; generating a polymorphic inline cache (PIC) code from a plurality of arguments, where the plurality of arguments are based on a result of the profiling step; generating a specialized method for a frequently appearing combination of the runtime types of argument and arguments that can be invoked from the PIC code; and inlining body of the specialized method into the call site if the specialized method has a body size within a permissible range.

摘要： Systems and methods for compiling source code are provided. In some aspects, a method includes receiving one or more code stubs configured to be inline cached at one or more call sites of a native code generated by a baseline compiler from a source code. Each of the one or more code stubs is based on an intermediate representation between the source code and the native code. The method also includes translating the source code into the intermediate representation, inlining the one or more code stubs into the translated source code, and optimizing, by an optimizing compiler, at least one of the translated source code and the inlined one or more code stubs.

摘要： A system and method for using inline stacks to improve the performance of application binaries is included. While executing a first application binary, profile data may be collected about the application that includes which callee functions are called from the application's callsites and the number of times each inline stack is executed. A context summary map may be created from the collected profile data which shows a summary of the total execution count of all instructions in the callee function for each callsite inlined in the application's normal binary. Using the context summary map, each function callsite's execution count may be compared with a predetermined threshold to determine if the function should be inlined. Then the application's profile may be annotated and a second application binary, an optimized binary, may be generated using the annotated profile.

摘要： Methods and apparatuses of converting a program, which may enhance an execution speed of a computer program, are provided. The method may include receiving a program, detecting at least one loop statement including at least one branch statement within the program, determining whether the loop statement may be split into at one or more sub-loop statements which perform the same function as a function of the loop statement and from which the branch statement has been removed, splitting the loop statement into the sub-loop statements and removing the branch statement included in the loop statement if it is determined that the loop statement may be split as a result of the determination, and outputting a result of removing the branch statement.

摘要： A parallelization assistant tool system to assist in parallelization of a computer program is disclosed. The system directs the execution of instrumented code of the computer program to collect performance statistics information relating to execution of loops within the computer program. The system provides a user interface for presenting to a programmer the performance statistics information collected for a loop within the computer program so that the programmer can prioritize efforts to parallelize the computer program. The system generates inlined source code of a loop by aggressively inlining functions substantially without regard to compilation performance, execution performance, or both. The system analyzes the inlined source code to determine the data-sharing attributes of the variables of the loop. The system may generate compiler directives to specify the data-sharing attributes of the variables.

摘要： A method and an apparatus for providing a flat array type in an object model for dynamically typed programs are described. Whether an array object is of a flat array type can be dynamically tracked for a dynamic language based program. Array elements of an array object of the flat array type may be stored in an inline storage within an object cell of the array object. The inline storage may be limited by available memory space between adjacent object cells. The flat array type of an array object may be detected based on whether the inline storage has sufficient memory space to store elements of the array. An array object of the flay array type may allow array elements of the array object to be accessed within a object cell without additional memory loading via a pointer stored in the object cell.

摘要： Disclosed herein are systems, methods, and computer-readable storage media for obfuscating using inlined functions. A system configured to practice the method receives a program listing including annotated functions for obfuscation, identifies an annotated function called more than once in the program listing, and creates an inline control flow structure in the program listing for the identified annotated function, the control flow structure being computationally equivalent to inlining the identified annotated function into the program listing for each occurrence of the identified annotated function. The program listing can include tiers of annotated functions. The system can identify annotated functions called more than once based on an optionally generated callgraph. The system can create inline control flow structures in the program listing in order of annotation importance. The system can identify how many times each annotated function is called in the program listing.

摘要： According to one embodiment of the present disclosure, hardware initialization code and error action information are retrieved from separate storage areas. The hardware initialization code includes code that initializes a device, and also includes placeholders corresponding to actions that are performed when the device fails initialization. Likewise, the error action information describes the actions that are performed when the device fails initialization. The error action information is converted into macros that include lines of code. As such, the error action placeholders are matched to the macros and, in turn, each of the error action placeholders is replaced with the lines of code corresponding to the matched macros.
