[jira] [Commented] (ARROW-8411) [C++] gcc6 warning re:
arrow::internal::ArgSort
[ https://issues.apache.org/jira/browse/ARROW-8411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17441836#comment-17441836 ]
Antoine Pitrou commented on ARROW-8411:
---------------------------------------
The diagnostic note makes the output a bit noisy but it is also entirely harmless, see [https://stackoverflow.com/questions/48149323/what-does-the-gcc-warning-project-parameter-passing-for-x-changed-in-gcc-7-1-m]
AFAIU it only manifests on ARM targets. We may want to disable the warning, but we may also not bother. cc [~yibocai]
