| | | | | | | | | | | | Gneral work on options in the client and server.
* | | Simplify the sdt semaphore decrement in utraceJosh Stone2009-09-172-39/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The decrement can happen at the same time that the utrace detach is called. However, I'm concerned that this code isn't correctly handling the case where multiple tasks may register the same probe, so for now I've noted those places. I think task finder may have to help in fixing this... * tapset-utrace.cxx (utrace_derived_probe_group::emit_module_init): As noted in uprobes-land, there's no need to tear down anything. (utrace_derived_probe_group::emit_module_exit): Unify the detach and semaphore decrement, and note a concern about multiple tasks. (utrace_derived_probe_group::emit_module_decls): Note same concern. * tapsets.cxx (uprobe_derived_probe_group::emit_module_decls): Ditto. (uprobe_derived_probe_group::emit_module_exit): Ditto.
* | | Simplify sdt's record_semaphoreJosh Stone2009-09-171-16/+5

* | | Map std semaphores from probe->addrJosh Stone2009-09-173-37/+23
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | Each probe needs to know the associated semaphore address, rather than the other way around. * session.h (sdt_semaphore_addr): Reverse the key-value types. * tapsets.cxx (record_semaphore): Take an index to only record the semaphore for newly added results. (sdt_query::handle_query_module): Adjust accordingly. (uprobe_derived_probe_group::emit_module_decls): Now it's a simple map lookup for sdt_sem_address. * tapset-utrace.cxx (utrace_derived_probe_group::emit_probe_decl): Ditto.

| * | Remove temporaries in netdev.change_macJosh Stone2009-09-171-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by dsmith, reusing temporary locals will prevent our limited optimizer from eliminating code. I'm getting rid of these particular locals altogether. * tapset/networking.stp (netdev.change_mac): Don't write mac intermediates into locals; just pass them directly to sprintf.
