- Peephole optimization is an optimization technique performed on a small set of compiler-generated instructions; the small set is known as the peephole or window. Peephole optimization involves changing the small set of instructions to an equivalent set that has better performance. For example:
* instead of pushing register A onto the stack and then immediately popping the value back into register A, a peephole optimization would remove both instructions;
* instead of adding A to A, a peephole optimization might do an arithmetic shift left;
* instead of multiplying a floating point register by 8, a peephole optimization might scale the floating point register's exponent by 3; and
* instead of multiplying an index by 4, adding the result to a base address to get a pointer value, and then dereferencing the pointer, a peephole optimization might use a hardware addressing mode that accomplishes the same result with one instruction. The term peephole optimization was introduced by William Marshall McKeeman in 1965. (en)
- コンパイラ理論において、のぞき穴的最適化（のぞきあなてきさいてきか、英語: Peephole optimization）とはごく小さな特定の命令列に対して行われる最適化の一種である。この組は”peephole”または"window"と呼ばれる。のぞき穴的最適化はより短い、または高速な命令に置き換えられる命令を探すことによって行われる。 (ja)
