While Erlang will use it's own atomic operations, it can also use gcc __atomic_* builtins. This is now listed in Erlang's HOWTO/INSTALL.md. This change was necessary on RISC-V, since Erlang didn't have a built-in implementation, but it was able to use gcc's __atomic_* functions.

Erlang is a programming language used to build massively
|
|
scalable soft real-time systems with requirements on high
|
|
availability. Some of its uses are in telecoms, banking,
|
|
e-commerce, computer telephony and instant messaging.
|
|
Erlang's runtime system has built-in support for
|
|
concurrency, distribution and fault tolerance.

The Megaco application is a framework for building

applications on top of the Megaco/H.248 protocol. It is
|
|
approximately 14MB in size so if you do not need it then
|
|
it is recommended not to enable it.
