- the broadest possible selection of target processors,
- a range of processors within a given processor architecture family,
- a single specific processor.
Generally speaking, the options do the following:
- -q32 selects 32-bit execution mode.
- -q64 selects 64-bit execution mode.
- -qarch selects the general family processor architecture for which instruction code should be generated. Certain -qarch settings produce code that will run only on systems that support all of the instructions generated by the compiler in response to a chosen -qarch setting.
- -qtune selects the specific processor for which compiler output is optimized. Some -qtune settings can also be specified as -qarch options, in which case they do not also need to be specified as a -qtune option. The -qtuneoption influences only the performance of the code when running on a particular system but does not determine where the code will run.

What is a metaphor for understanding the Java Virtual Machine?
It helps to think of the JVM as a "virtual processor"; instead of compiling a program for a specific real processor, the Java compiler compiles for this virtual processor. The advantage of doing so is that, even though the program ultimately runs on different machines (different processor types), it only needs to be compiled only once.
What is the difference between compiler and program?
A compiler is actually a program. However the function of a compiler it to take a programmers high level language code and render this as binary machine language instructions that a specific processor can execute.
What is Language processor?
Language processors are language translation software like assembler, interpreter and compiler
What is the use of compiler?
Compiler is used to convert a language readable in user domain into the tasks which is understood by the machine. example: C++ compiler compiles program written in a langauge understood by user which compiles this to a task which can be executed by a computer's processor.

What is compiler writing tool?
they are tools to help developed compilers
Is turbo c software a word processor software?
Turbo C is a free C++ compiler from Borland. It comes with an IDE and debugger. It lets you compile and run C++ applications on your computer. It is not a word processor.
What are register variables What are the advantage of using register variables?
Asks the compiler to devote a processor register to this variable in order to speed the program's execution. The compiler may not comply and the variable looses it contents and identity when the function it which it is defined terminates.

What is a chip that runs a PC's unit?
It is called a micro-processor......a processor on a single chip
Why would a program be written in assembly language instead of basic language?
To allow use of special instructions that the HLL compiler/interpreter cannot generate. These are often special I/O or multiprocessor synchronization instructions unique to this processor architecture.To produce timing or space critical code.To write the bootstrap program.To write a program for a new custom processor for which no HLL compiler/interpreter has been written, yet. This might be the first development version of that first HLL compiler/interpreter.etc.
What is the difference between GCC compiler and turbo c compiler?
1. The Gcc compiler cna support multiple languages such as c,c++,Java,Fortran,Pascal etc.... Whereas in turbo c cpmpiler,it doesn't support multiple languages. 2. GCC compiler is a free software,... Whereas in turbo c cpmpiler , it is not a free software. 3. The GCC compiler is is a portable compiler,it runs on most plateform avilable today... Whereas in turbo c cpmpiler, it is not a portable compiler.
