From: Frank Hunleth Date: Sat, 8 May 2021 22:24:19 +0000 (-0400) Subject: package/erlang: support build when gcc __atomic_* exist X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0bab8c1089983a4b5f0f2acfe5cad77b02d6f654;p=buildroot.git package/erlang: support build when gcc __atomic_* exist 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.
