# test that we can re-set breakpoints in shared libraries
# APPLE LOCAL: The Apple model of breakpoints is a bit different than most
# others. On e.g. a Linux box, doing "break shr1" pre-execution will put
# the breakpoint on the dyld trampoline address. When the library is loaded
# into memory at run-time, the bp address is updated.
# On an Apple system, gdb loads the symbols for all shared libraries that
# have specified load addresses when you do "file shmain", so it knows where
# the breakpoints will really go. shr1.sl and shr2.sl don't have specified
# load addresses, so their symbols aren't loaded until runtime.
#
# You could imagine a hybrid where Apple gdb would back off to setting the
# bp on the dyld trampoline, but it's unlikely to happen any time soon.
gdb_test "future-break shr1" "Breakpoint 1.*" "set bp in shared library"
# FIXME: should not send "run" explicitly. Non-portable.
