(ld_so_xfer_auxv, memory_xfer_auxv): New function. * auxv.h (procfs_xfer_auxv): Remove comment. Rename to ... (memory_xfer_auxv): ... here. * linux-nat.c (linux_xfer_partial): Rename procfs_xfer_auxv to memory_xfer_auxv. * procfs.c (procfs_xfer_partial): Likewise. * solib-svr4.c (svr4_relocate_main_executable): New prototype. (svr4_special_symbol_handling): Call svr4_relocate_main_executable. (svr4_solib_create_inferior_hook): Conditionalize the svr4_relocate_main_executable call. gdb/testsuite/ * gdb.base/valgrind-db-attach.exp, gdb.base/valgrind-db-attach.c: New. --- gdb/testsuite/gdb.base/valgrind-db-attach.c | 30 +++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gdb/testsuite/gdb.base/valgrind-db-attach.c (limited to 'gdb/testsuite/gdb.base/valgrind-db-attach.c') diff --git a/gdb/testsuite/gdb.base/valgrind-db-attach.c b/gdb/testsuite/gdb.base/valgrind-db-attach.c new file mode 100644 index 0000000..5faaaac --- /dev/null +++ b/gdb/testsuite/gdb.base/valgrind-db-attach.c @@ -0,0 +1,30 @@ +/* This testcase is part of GDB, the GNU debugger. + + Copyright 2009 Free Software Foundation, Inc. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
