From 1d35b6054a9b94b48511e23a7fab6cd1dbf3fde6 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Thu, 6 Aug 2020 23:17:32 -0700 Subject: scripts/bloat-o-meter: Support comparing library archives Library archives (.a) usually contain multiple object files so their output of nm --size-sort contains lines like: 00000000000003a8 t run_test extent-map-tests.o: bloat-o-meter currently doesn't handle them which results in errors when calling .split() on them. Fix this by simply ignoring them. This enables diffing subsystems which generate built-in.a files.
