Abstract
Techniques are described for unifying static and dynamic compiler optimizations in source code bases. In an embodiment, a first compiler compiles source code of a target function to generate ahead-of-time (AOT) compiled machine code. A second compiler compiles the source code to generate an intermediate representation (IR) of the target function. In response to determining that the target function should be just-in-time (JIT) compiled, the AOT-compiled machine code for the target function is linked to the IR of the target function. During runtime, a physical processor executes AOT-compiled machine code of an executable program. When the target function is encountered for the first time, a JIT compiler is invoked. The JIT compiler generates JIT-compiled machine code for the target function. The physical processor executes the JIT-compiled machine code in place of the AOT-compiled machine code for the target function.
