Question

I am just starting with g++ compiler on Linux and got some questions on the compiler flags. Here are they

Optimizations

I read about optimizatio

Answer 1

There are many optimizations that a compiler can perform, other than loop unrolling and inlining. Loop unrolling and inlining are specifically mentioned there since, although they make the code faster, they also make it larger.

To make a static library, use 'g++ -c' to generate the .o files and 'ar' to archive them into a library.
