Added compiler option that does not include unused function / modules in the output image

However, the documentation page doesn't indicate this flag affects whether an unused function or module is in the final output image. Typically, I would expect Link-Time-Optimization (LTO) to remove unused functions and modules. Does the placement location of string literals impact LTO?

Can you help me understand the source that suggested this happens via the use of this parameter?
