Generate assembly output from Rust code using the rustc --emit=asm flag.
Use the rustc compiler with the --emit=asm flag to generate assembly code for your Rust source file. Run the following command in your terminal, replacing main.rs with your specific file path:
rustc --emit=asm main.rs -o main.s
This compiles main.rs and outputs the assembly code to a file named main.s in the current directory.
Viewing generated assembly from Rust code translates your source into the low-level instructions your computer's processor understands. It is like asking a translator to convert a novel into a specific dialect so you can see exactly how the words are spoken. You use this to debug performance issues or to understand how Rust optimizes your code.
