The patch reads:

+  /* If 'shrinkable' is FALSE, do not shrink by deleting bytes while
+     relaxing. Such shrinking can cause issues for the sections such 
+     as .vectors and .jumptables. Instead the unused bytes should be 
+     filled with nop instructions. */
+  bfd_boolean shrinkable = TRUE;
+  if (!strcmp (sec->name,".vectors")
+      || !strcmp (sec->name,".jumptables"))
+    shrinkable = FALSE;

Shouln't this also cover .jumptables* and .progmem.gcc* ?

avr-gcc puts its jumptables into .progmem.gcc_sw_table for instance.

Relaxing must not do harm to them.
