+    commit 29a39c12bb818c552b1575b28ebef1a8c4089b04
+
+    Now builds a new opscounttab which has the change in
+    the size of the expression stack for each DW_OP.
+    To enable the print_die.c changes.
+        modified:   src/bin/buildopstab/buildopscounttab.c
+        modified:   src/bin/dwarfdump/opscounttab.c (regenerated)
+        modified:   src/bin/dwarfdump/opscounttab.h (new field added)
+
+    Unless the expression is trivial
+    printing expressions (DW_OP_swap etc)
+    -v -i now adds a line like
+      DW_OPs= 13 maxstackdepth= 4 endingstackdepth= 3
+    at the end of the list of DW_OP expression operations
+    as a shorthand for the instructions and their
+    use of an expression stack.
+    If there are expression loops It adds
+      loopcount= <n>
+    to the end of the line (counting the
+    instances of a DW_OP_bra or DW_OP_skip
+    in a negative direction).
+        modified:   src/bin/dwarfdump/print_die.c
+
+    The old names of these functions were a bit
+    misleading. They are for all expressions.
