A method includes generating output code based on input code using a compiler or translator and providing the output code to one or more platforms for execution. The method also includes receiving feedback associated with the execution of the output code, where the feedback identifies at least one of: one or more failures during the execution of the output code and one or more performance characteristics of the execution of the output code. The method further includes modifying the compiler or translator based on the feedback and generating additional output code using the modified compiler or translator.

A method may include receiving, by a privileged component executed by a processing device, bytecode of a packet processing component from an unprivileged component executed by the processing device, analyzing, by the privileged component, the bytecode of the packet processing component to identify whether the bytecode comprises a first command that returns a redirect, analyzing, by the privileged component, the bytecode of the packet processing component to identify whether the bytecode comprises a second command that returns a runtime computed value, and responsive to determining that the bytecode comprises the first command or the second command, setting a redirect flag maintained by the privileged component.

Provided are embodiments that include a system configured to generate executable code with protection barrier instructions. The system includes a storage medium, the storage medium being coupled to a processor. The processor is configured to analyze code, mark one or more potentially unsafe instructions in the code, and identify one or more unsafe instructions from the marked one or more potentially unsafe instructions in the code. The processor is also configured to insert a protection barrier instruction into the code based at least in part on identifying the one or more unsafe instructions, and translate the code, responsive to inserting the protection barrier instruction. Also provided are embodiments for a computer-implemented method and a computer program product for generating executable code with protection barrier instructions.

A compiler configured to configure memory nodes with a ready-to-read credit counter and a write credit counter. The ready-to-read credit counter of a particular upstream memory node initialized with as many read credits as a buffer depth of a corresponding downstream memory node. The ready-to-read credit counter configured to decrement when a buffer data unit is written by the particular upstream memory node into the corresponding downstream memory node, and to increment when the particular upstream memory node receives from the corresponding downstream memory node a read ready token. The write credit counter of the particular upstream memory node initialized with one or more write credits and configured to decrement when the particular upstream memory node begins writing the buffer data unit into the corresponding downstream memory node, and to increment when the particular upstream memory node receives from the corresponding downstream memory node a write done token.

Specific images of an OS are built using only the driver bindings that are necessary to link the OS to the particular hardware of a client device. A device tree of the client device is analyzed to identify the hardware components. Databases of different hardware source code for various hardware drivers are maintained and used to craft the driver bindings and instances for the hardware of the client device. The device tree is also analyzed to identify compatibility strings of the various hardware on the client device. The hardware source code is searched for these compatibility strings to see if a driver exists in the databases of hardware source code. Specific driver bindings and driver instances with the actual variable names and configuration parameters of the identified hardware drivers are then generated and included in an image of the OS that may be installed on the client device.

Provided are embodiments for a method of performing register pressure targeted function splitting. The method can include determining a candidate region of a function, the candidate region comprising variables, and determining a number of available registers in a computing system for allocating the variables of the function. The method can also include grouping the variables in the candidate region into first variables and second variables based at least in part on the number of available registers, and splitting the candidate region of the function into split functions based at least in part on the grouping of the variables. Also provided are embodiments for a computer program product and a system for performing register pressure targeted function splitting
