scripts/bloat-o-meter: add -p argument
When doing cross platform development on a machine sometimes it might be useful to invoke bloat-o-meter for files which haven't been build with the native toolchain. In cases when the host nm doesn't support the target one then a toolchain-specific nm could be used. Add this ability by adding the -p allowing invocations as: ./scripts/bloat-o-meter -p riscv64-unknown-linux-gnu- file1.o file2.o Link: https://lkml.kernel.org/r/20220701113513.1938008-2-nborisov@suse.com Signed-off-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
