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.
