Abstract: The disclosed embodiments provide a system that facilitates execution of a software program. During operation, the system obtains one or more user-defined rules for configuring a memory layout of an object instance in a software program, wherein the one or more user-defined rules are created separately from source code for the software program. Next, the system generates the memory layout of the object instance by applying the one or more user-defined rules to one or more fields of the object instance. The system then executes the software program using the generated memory layout of the object instance.

Abstract: The disclosed embodiments provide a system that facilitates the execution of a software program. During operation, the system determines a structure of a software program and an execution context for the software program from a set of possible execution contexts for the software program, wherein the software program includes one or more object instances. Next, the system uses the structure and the execution context to identify a portion of an object instance from the one or more object instances that is determined to inefficiently use memory space in the software program. The system then provides a refactoring of the object instance that reduces use of the memory space in the object instance.

Abstract: The disclosed embodiments provide a system that facilitates the execution of a software program. During operation, the system obtains a set of artifacts associated with executing a software program. Next, the system uses the set of artifacts to determine an inheritance hierarchy associated with an artifact from the set of artifacts. The system then uses the inheritance hierarchy and the set of artifacts to generate a memory layout of an object instance represented by the artifact, wherein the memory layout includes a set of fields associated with a set of levels of the inheritance hierarchy.

Abstract: The disclosed embodiments provide a system that facilitates execution of a software program. During operation, the system displays a visualization of a memory layout of an object instance in a software program, wherein the visualization includes one or more fields in the object instance. Next, the system receives user input that customizes the memory layout. The system then processes the user input by updating the displayed visualization to reflect customization of the memory layout by the user input and storing, in association with the software program, one or more rules that, when processed during instantiation of the object instance, configure the memory layout of the object instance based on the user input.

Abstract: The disclosed embodiments provide a system that facilitates execution of a software program. During operation, the system obtains an execution unit associated with execution of a software program, wherein the execution unit includes a start and an end. Next, the system identifies a set of fields accessed within the execution unit. The system then calculates one or more memory distances among the set of fields from a set of memory addresses of the set of fields during runtime of the software program on the computer system, wherein the one or more memory distances include a difference in memory address between a first field and a second field in the set of fields. Finally, based at least in part on a memory distance in the one or more memory distances exceeding a threshold, the system stores an indication that the execution unit has a suboptimal memory layout.

Abstract: The disclosed embodiments provide a system that facilitates the execution of a software program. During operation, the system obtains a memory layout for an object instance in a software program, wherein the memory layout includes a set of offsets and a set of allocated sizes of a set of components associated with the object instance. Next, the system uses the memory layout to determine a first memory space occupied by data in the object instance and a second memory space occupied by padding in the object instance. The system then displays a visualization of the memory layout on the computer system, wherein the visualization includes a first graphical distinction between the first memory space and the second memory space.

Abstract: The disclosed embodiments provide a system for densely storing strings within the memory of a software program. During operation, the system receives a set of characters to be stored in a string, wherein each character is encoded using a multi-byte public encoding. The system then stores the set of characters in the string at least in part by performing the following steps. The system determines whether every character of the set can be encoded using a first private encoding that consumes less space per character than the multi-byte public encoding. Responsive to determining that every character of the set can be encoded using the first private encoding, the system stores a particular value associated with the first private encoding in a particular field of the string. The system then stores the set of characters in the string in the first private encoding.
