-    libasm: Fix GCC7 one -Wformat-truncation=2 warning.
-    
-    Make sure that if we have really many labels the tempsym doesn't get
-    truncated because it is too small to hold the whole name.
-    
-    This doesn't enable -Wformat-truncation=2 or fix other "issues" pointed
-    out by enabling this warning because there are currently some issues
-    with it. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79448

-Subject: [PATCH] ppc64: Add minimal fallback unwinder.
-
-This adds a minimal fallback unwinder for ppc64[le] in case we cannot find
-CFI for a particular address. It simply always sets the program counter to
-the link register, picks the previous stack pointer from the backchain,
-and the previous link register from the LR save area.
-
-This is enough for some simple situations when we don't have CFI and
-seems to work nicely in the case of perf with libdw powerpc support:

+Subject: [PATCH 1/2] libdw: dwarf_aggregate_size() works with
+ multi-dimensional arrays
+
+If we have a multidimensional array of dimensions (a,b,c) the number of elements
+should be a*b*c, but prior to this patch dwarf_aggregate_size() would report
+a+b+c instead.
+
+This patch fixes the bug and adds a test that demonstrates the bug (the test
+fails without the functional part of this patch).
