# Test that "catch fork" works on static executables.

# For instance, on Linux we need PTRACE_O_TRACEFORK set before the program
# reaches the fork.  GDBserver was only setting flags when it reached the first
# stop *after* arch_setup.  In a dynamic executable there is often a swbreak in
# ld.so probes before reaching main, and ptrace flags were set then.  But a
# static executable would just keep running and never catch the fork.

if { [is_remote target] || ![isnative] } then {
    continue
}

# Until "catch fork" is implemented on other targets...
#
if { ![istarget "*-*-linux*"] && ![istarget "*-*-openbsd*"] } then {
    continue
}

# Reusing foll-fork.c since it's a simple forking program.
