New test for follow-exec-mode
This patch implements a new GDB test for follow-exec-mode. Although
there is a GDB test for debugging across an exec, there is no test for
follow-exec-mode. This test is derived from gdb.base/foll-exec.exp,
and re-uses execd-prog.c as the program to exec.
The following behavior is tested:
follow-exec-mode == "same"
- 'next' over the exec, check for one inferior
- 'continue' past the exec to a breakpoint, check for one inferior
- after the exec, use a 'run' command to run the current binary
follow-exec-mode == "new"
- 'next' over the exec, check for two inferiors
- 'continue' past the exec to a breakpoint, check for two inferiors
- after the exec, use a 'run' command to run the current binary
- after the exec, use the 'inferior' command to switch inferiors,
then use a 'run' command to run the current binary
Note that single-step breakpoints do not survive across an exec.
There has to be a breakpoint in the execed program in order for
it to stop right after the exec.
gdb/testsuite/ChangeLog:
* gdb.base/foll-exec-2.c: New test program.
* gdb.base/foll-exec-2.exp: New test.
