Hello!
gcc.target/i386/chkp-strlen-2.c testcase uses stpcpy, which with older
glibc requires _GNU_SOURCE.
The patch also moves some definitions from compile flags to the source.
2016-01-23 Uros Bizjak <ubiz...@gmail.com>
* gcc.target/i386/chkp-strlen-2.c: Define _GNU_SOURCE.
* gcc.target/i386/chkp-strlen-4.c: Move the definition of
_GNU_SOURCE from compile flags to the source.
* gcc.target/i386/chkp-stropt-12.c: Ditto.
* gcc.target/i386/chkp-stropt-16.c: Ditto.
* gcc.target/i386/chkp-stropt-4.c: Ditto.
* gcc.target/i386/chkp-stropt-8.c: Ditto.
Tested on x86_64-linux-gnu and committed to mainline SVN.
Uros.
