I'm still looking for a review of the patch below:
https://gcc.gnu.org/ml/gcc-patches/2016-10/msg00043.html
The patch should clean up the remaining test suite failures on
ILP32 targets and also fixes up some remaining issues in the
gimple-ssa-sprintf pass that stand in the way of re-enabling
the printf-return-value optimization.
I'm traveling next week so I'm hoping to enable the optimization
shortly after this patch goes in so that if there's any fallout
from it I can fix it before I leave.
Thanks
Martin

The attached patch fixes a number of outstanding test failures
and ILP32-related bugs in the gimple-ssa-sprintf pattch pointed
out in bug 77676 and 77735). The patch also fixes c_strlen to
correctly handle wide strings (previously it accepted them but
treated them as nul-terminated byte sequences), and adjusts the
handling of "%a" to avoid assuming a specific number of decimal
digits (this is likely a defect in C11 that I'm pursuing with
WG14).
Tested on powerpc64le, i386, and x86_64.
There is one outstanding failure in the builtin-sprintf-warn-1.c
test on powerpc64le that looks like it might be due to the
printf_pointer_format target hook not having been set up entirely
correctly. I'll look into that separately, along with pr77819.
