- Cross-compiler is a compiler
- a) Which is written in a different language from the source language?
- b) That generates object code for the machine it’s running on.
- c) Which is written in the same language as the source language?
- d) That runs on one machine but produces object code for another machine
Answer
Answer: a
Explanation: A compiler for a high-level language that runs on one machine and produces code for a different machine is called a cross compiler.
- Cross compiler is used in Bootstrapping.
- a) True
- b) False

- b) No
Answer

- The __________ is a technique for building cross compilers for other machines
- a) Brazilian Cross
- b) Canadian Cross
- c) Mexican Cross
- d) X-cross
Answer
Answer: b
Explanation: The Canadian Cross is a technique for building cross compilers for other machines. Given three machines X, Y, and Z, one uses machine X (e.g. running Windows XP on an IA-32 processor) to build a cross compiler that runs on machine Y (e.g. running Mac OS X on an x86-64 processor) to create executables for machine Z.
- __________ was developed from the beginning as a cross compiler
- a) Free Pascal
- b) GCC
- c) Pascal
- d) None of the mentioned
Answer
Answer: a
Explanation: Free Pascal was developed from the beginning as a cross compiler. The compiler executable (ppcXXX where XXX is target architecture) is capable of producing executables for all OS of the same architecture.
