Extended-remote exec test
This patch updates several exec-related tests and some of the library functions in order to get them running with extended-remote. There were three changes that were required, as follows: In gdb.base/foll-exec.exp, use 'clean_start' in place of proc 'zap_session' to reset the state of the debugger between tests. This sets 'remote exec-file' to execute the correct binary file in each subsequent test. In gdb.base/pie-execl.exp, there is an expect statement with an expression that is used to match output from both gdb and the program under debug. For the remote target, this had to be split into two expressions, using $inferior_spawn_id to match the output from the program. Because I had encountered problems with extended-remote exec events in non-stop mode in my manual testing, I added non-stop testing to the non-ldr-exc-[1234].exp tests. In order to set non-stop mode for remote targets, it is necessary to 'set non-stop on' after gdb has started, but before it connects to gdbserver. This is done using 'save_vars' to set non-stop mode in GDBFLAGS, so GDB sets non-stop mode on startup. gdb/testsuite/ChangeLog: * gdb.base/foll-exec.c: Add copyright header. Fix formatting issues. * gdb.base/foll-exec.exp (zap_session): Delete proc. (do_exec_tests): Use clean_restart in place of zap_session, and for test initialization. Fix formatting issues. Use fail in place of perror. * gdb.base/pie-execl.exp (main): Use 'inferior_spawn_id' in an expect statement to match an expression with output from the program under debug. * gdb.threads/non-ldr-exc-1.exp (do_test, main): Add non-stop tests and pass stop mode argument to clean_restart. Use save_vars to enable non-stop in GDBFLAGS. * gdb.threads/non-ldr-exc-2.exp: Likewise. * gdb.threads/non-ldr-exc-3.exp: Likewise. * gdb.threads/non-ldr-exc-4.exp: Likewise.
