compiler directive
A computing term for an instruction embedded in source code that controls compiler behavior, such as pragmas or preprocessor directives.
This compiler directive specifies the optimization level.
コンパイラ is the compiler itself, while 翻訳コンパイラ指示文 is a specific instruction given to the compiler.
指示文 is a general directive or instruction statement; 翻訳コンパイラ指示文 is specifically a compiler directive in a programming context.
Compound of 翻訳 (translation, here referring to compilation), コンパイラ (compiler), and 指示文 (directive statement). A technical term likely calqued from English 'compiler directive'.
