+# 2. extract only those lines that we are interested in via `grep`
+# 3. from those lines, extract just the symbol name via `sed`, which:
+# * always starts with "_ZN" and ends with "E" (`legacy` mangling)
+# * always starts with "_R" (`v0` mangling)
+# 4. sort those symbol names for deterministic comparison
