Since upstream gcc has recently increased the function alignment on
S390, the dw2-dir-file-name test case fails in the first gdb_continue_to_breakpoint. Indeed, the breakpoint is now placed into the alignment gap *before* the actual function. This happens because the test case declares the respective "*_start" symbol as a "loose" label before the function definition, and the compiler inserts the alignment between that label and the function itself. The "*_start" symbols were only necessary because FUNC made the function static. The fix makes the functions extern instead, thus making the "*_start" labels unnecessary. testsuite/ 2014-01-10 Andreas Arnez <arnez@linux.vnet.ibm.com> Pedro Alves <palves@redhat.com> * gdb.dwarf2/dw2-dir-file-name.c (FUNC): Remove "*_start" symbol. Make "name" extern. * gdb.dwarf2/dw2-dir-file-name.exp (out_cu, out_line): Replace references to ${name}_start by references to ${name}.
