# This zig_default_flags below is meant to avoid CPU feature impurity in
|
|
# Nixpkgs. However, this flagset is "unstable": it is specifically meant to
|
|
# be controlled by the upstream development team - being up to that team
|
|
# exposing or not that flags to the outside (especially the package manager
|
|
# teams).
|
|
|
|
# Because of this hurdle, @andrewrk from Zig Software Foundation proposed
|
|
# some solutions for this issue. Hopefully they will be implemented in
|
|
# future releases of Zig. When this happens, this flagset should be
|
|
# revisited accordingly.
