While I was trying to fit an application in a limited space I noticed that the compiler/linker does not appear to remove functions that are uncalled across C files.
I have a number of C files that are common to a number of applications but not all of these functions are called by all applications.
If I comment out these functions the application will then reduce in size, so I am pretty sure the linker is not removing these (or at least part of these) unused functions. This is regardless of the optimisation level I have set for the compiler.
Ideally I want the compiler/linker to remove these functions automatically.
I have trawled through the options on armlink but I cant seem to find what I want.
I am pretty sure I am missing something obvious. So can anyone explain how I achieve this?
Thanks
