Latest Patents

Wenlei He’s latest patents include innovative methods that enhance program optimization and compilation processes. One of his patents, titled "Sample driven profile guided optimization with precise correlation," describes a profile-guided optimization compiler that utilizes sample profile data. This data includes a control flow representation of a program, which has block counts associated with each basic block and edge counts estimated from these block counts. The correlation data allows for precise mapping of sampled instructions from optimized binaries back to the corresponding basic blocks of source code, improving the efficiency of the optimization process.

Another significant patent is "Incremental whole program compilation of code." This invention provides methods and systems for incremental compilation of source code. It involves storing attributes of an intermediate language representation and a compiled representation of the source code. When modified source code is received, the system generates an intermediate representation and compares it with stored attributes to identify functions that have changed. This process allows for efficient recompilation of only the affected functions, streamlining the overall compilation process.
