Hello! 👋

Note: This is an LLM-translated version from Simplified Chinese. Please be aware of potential translation errors. Introduction Modern compilers can infer variable values in program code to eliminate certain computation instructions and branches, thereby reducing runtime overhead of compiled artifacts. With these optimizations, programmers can typically obtain well-optimized compiled output while maintaining code readability, without manually specializing each variable. Compilers can infer a variable’s value or range through branch conditions or assertions. Here’s a simple example: ...
