What is a compiler called that runs on one machine but produces code for another________________?
Show answer Hide answer
Answer: A. cross compiler
Explanation
A cross compiler runs on one machine architecture but produces code for another. It translates source code into machine language targeting a different hardware platform. Cross-compilation is essential when target devices lack resources to compile software locally. Embedded systems and microcontrollers often lack the memory needed to host compilers. Development workstations provide powerful host environments to build software for target devices. Compiler toolchains are configured with target architectures specified during build setup.
Embedded firmware engineers compile ARM microcontroller software on powerful x86 desktop computers. Video game developers build console software using cross compilers running on standard PCs. Mobile application toolchains cross compile native C libraries for deployment across device CPUs. One pass compiler processes source code in a single reading without multi-pass optimization. Multipass compiler reads source code multiple times to perform advanced code optimizations. Optimizing compiler focuses on improving execution speed and reducing code size regardless of target.
