\texttt{gcc} has (as of \texttt{GCC 15.2.1 20260103} on Arch Linux) about 1000 CLI arguments that can be passed.
Below is a list of the most important flags that can be passed, as discussed in the lectures:
\begin{tables}{ll}{Flag & Description}
\texttt{-E} & Stop after the preprocessor (output is a \texttt{.i} file) \\
\texttt{-S} & Stop after the compiler (output is assembly in \texttt{.s} file) \\
\texttt{-c} & Stop after the assembler (output is \texttt{.o} file) \\
\texttt{-o} & Specify the executable name \\
\texttt{-DNDEBUG} & Removes all assert statements \\

\texttt{-Wextra} & Enable more warnings \\
\texttt{-Werror} & Makes all warnings errors \\
\texttt{-march=XXX} & Optimize for the architecture (can be e.g. \texttt{native}, \texttt{x86-64-v4}, \dots) \\
\texttt{-fno-tree-vectorize} & Do not vectorize code (\texttt{-O3} commonly enables vectorization) \\
