We enable systemtap probe in glibc recently, and see the following gdb fail, (gdb) set solib-absolute-prefix /. ... Stopped due to shared library event:^M Inferior loaded /./foo/bar/gdb.base/break-probes-solib.so ... (gdb) FAIL: gdb.base/break-probes.exp: run til our library loads (the program exited) $binfile_lib is /foo/bar/gdb.base/break-probes-solib.so, but the sysroot is prefixed in solib.c:solib_find, as comments described: Global variable GDB_SYSROOT is used as a prefix directory to search for shared libraries if they have an absolute path. so the output becomes "/./foo/bar/gdb.base/break-probes-solib.so", which is still correct. However, the test repeatedly continue the program and tries to match $binfile_lib, finally, the program exits and the test fails. This patch is to adjust the pattern to match $sysroot$binfile_lib instead of $binfile_lib. gdb/testsuite: 2014-11-28 Yao Qi <yao@codesourcery.com> * gdb.base/break-probes.exp: Match library name prefixed with sysroot.
