Subject: gdb-rhbz1084404-ppc64-s390x-wrong-prologue-skip-O2-g-3of3.patch

;; Fix '[ppc64] and [s390x] wrong prologue skip on -O2 -g code' (Jan

;; Kratochvil, RH BZ 1084404).

;;=fedoratest

These testcases have been created by compiling glibc-2.17-78 on

RHEL-7.1 s390x/ppc64 boxes, and then taking the "select.o" file

present at $builddir/misc/select.o.
