Latest Patents
Pratap holds a patent titled "Sample driven profile guided optimization with precise correlation." This patent describes a profile guided optimization compiler that utilizes sample profile data, including a control flow representation of a program. The compiler incorporates block counts associated with each basic block of the program and edge counts estimated from these block counts. The innovative aspect of this patent lies in its ability to use correlation data to map the address of a sampled instruction from a fully optimized binary directly into the corresponding basic block of source code control flow. This method employs a relative virtual address (RVA) associated with each source code basic block and the sampled instruction. The correlation data allows for differentiation between multiple blocks on the same source code line, handling inlining and optimizations with greater precision and efficiency. The block counts are then utilized to guide the optimization of the program effectively.
