strip(1) reduces the size of an application in the file system by removing the debug info.

If you want to see the size of various elements in a binary use nm(1). nm --print-size --size-sort might give you some hints where to start remving elements.

If you compile with -fdata-sections -ffunction-sections and link with --gc-sections the linker automatically removes all unused code and all unused data. That is typically easier than gnatelim.
