Should I be suggesting to upstream to attempt to detect CPU before running non-available instructions, eg as part of app startup ?
Further, what can I run over an existing executable to detect what CPU it was built for, ie what instuctions have been included ?
Yes, all the packages which have WORKING support for SSE etc. in Fedora do that. See e.g. https://projects.kde.org/projects/kde/kdelibs/repository/revisions/master/en... https://projects.kde.org/projects/kde/kdelibs/repository/revisions/master/en... https://projects.kde.org/projects/kde/kdelibs/repository/revisions/master/en... for the implementation Solid (in kdelibs) uses.
Thanks Kevin, I'll make the suggestion to developers, and see if they are interested. Cheers, David.
