This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-lto". Some packages used LTO, but not the linker plugin. This unifies 'em all to attempt to produce better code. Quoting man gcc(1): "This improves the quality of optimization by exposing more code to the link-time optimizer." Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed that every buildsystem uses +$(MAKE) correctly. Signed-off-by: Andre Heider <a.heider@gmail.com>

|
|
The libevent API provides a mechanism to execute a callback function
|
|
when a specific event occurs on a file descriptor or after a timeout
|
|
has been reached. Furthermore, libevent also support callbacks due
|
|
to signals or regular timeouts.
|
|
|
|
libevent is meant to replace the event loop found in event driven
|
|
network servers. An application just needs to call event_dispatch()
|
|
and then add or remove events dynamically without having to change
|
|
the event loop.
