- Compilers can optimize complex loops into single instructions.
- Different unsigned addition routines are compiled into the same efficient ARM instruction.
- Recursive functions can also be optimized to simple instructions via tail-call optimization.
- Compilers use intermediate representations to standardize and simplify code patterns.
- Pattern recognition in compilers is robust, handling even poorly written code.
- The post is part of the 'Advent of Compiler Optimisations 2025' series.
- Compiler Explorer is a tool mentioned for experimenting with compiler optimizations.
