Subject: hppa: fix loading of global pointer in _start [BZ #20277]
X-Git-Tag: glibc-2.24~53
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9765ffa71030efd8bb4f2ea4ed6e020fcb4bb714;p=thirdparty%2Fglibc.git

hppa: fix loading of global pointer in _start [BZ #20277]

The patched change fixes a regression for executables compiled with the
-p option and linked with gcrt1.o.  The executables crash on startup.

This regression was introduced in 2.22 and was noticed in the gcc testsuite.
