Oh, a divmod issue. At least it's not using modsi3 ;) (llvm #26450)
BTW, the attached assembly files were generated with lto and NEON enabled but
the 20% difference stayed the same. (1s vs 1.2s)

Looks like for some reason with profiling __aeabi_idiv/__aeabi_idivmod is being
used in one place.
Most likely for pos / 9 .

D Hugh Redelmeier in comment 12 is mistaken... memcpy is a reserved identifier
(see e.g. http://stackoverflow.com/a/23841970), so the user cannot legally
redefine it.

This bug could be reproduced with gcc 7.0.0 20160424 on x86-64 with this
example:
int main()

volatile struct {
char s[8193]; // gcc
//char s[129]; // clang
} s = {""};
s = s;
}

Unfortunately this bug affects versions shipping with Debian and Ubuntu, e.g.
gcc version 5.3.1 20160413 (Ubuntu 5.3.1-14ubuntu2)
which is the version included in the lastest Ubuntu release 16.04.
