Summary
Jason explores the various compiler optimization flags available in GCC and Clang, explaining the differences between -O0 (no optimization), -O1/2/3 (increasing optimization levels), -Os (optimize for size), -Og (optimize for debugging experience), -Ofast (disregards strict standards compliance), and Clang's unique -Oz flag (further size optimization). Using an ARM emulator example, he demonstrates how different optimization levels affect the resulting binary size and notes that the optimal choice depends on specific project requirements.
