For users not familiar with the ARM arch, neon is arguably more likely to |
14 |
be associated with net-libs/neon. Certainly that's what I would have |
15 |
immediately thought, tho my only familiarity with the library is as a |
16 |
dependency that IIRC used to trigger lots of subversion rebuilds, etc |
17 |
(now days I don't even have subversion on the system, it's all git, but |
18 |
according to equery d, neon is still required by musicbrainz). |

As such, to avoid confusion I'd suggest arch-neon or arm-neon (or armneon/ |
21 |
archneon) if it's to be a global flag. |

YMMV... |
