Questions tagged [compiler-options]

Compiler-options are parameters that are being passed to the compiler and that affect the compilation process or its resulting product.

Modern compilers have a large set of options that can be used to somehow change the way the code is compiled. Usually those options are passed as command-line flags.

Example for Java:

javac -target 1.5 -bootclasspath jdk1.5.0\lib\rt.jar \ -extdirs "" OldCode.java

More information about particular options can be found on compiler vendor's websites, to name a few:

How to disable compiler optimizations in gcc?

I am trying to learn assembly language. I have searched and found how to disassemble a .c file but I think it produces some optimized version of the program. Is there any way so that I can see the exact assembly code which corresponds to my C file.
