[PATCH] D126984: [clang] Add initial support for gcc's optimize function attribute

[Dávid Bolvanský via Phabricator via cfe-commits]

xbolva00 added a comment.

"The optimize attribute should be used for debugging purposes only. It is not suitable in production code."

Until they (users) start and any change in pipeline may surprise them.

Personally I am bigger fan of more targeted attributes like we have noinline / noipa proposed but stalled /  and then we could have new ones to disable vectorizers, LICM, unroller, etc..

Yes, we could claim that attribute((optimize("-fno-slp-vectorize") then maps exactly to attribute((noslp)).

Still, I would like to hear some motivation words other than "gcc" has it.
