Subject: [PATCH] Fix building with gcc 16 (evex512 removal)
|
|
|
|
Recently, evex512 was removed from gcc trunk [1] which will eventually
|
|
become gcc 16, and that leads to a build failure in
|
|
mariadb, originally reported downstream in a Gentoo bug [2].
|
|
|
|
This is reproducible across all versions from 10.6 to current master.
|
|
|
|
The change is as simple as adding an upper boundary to which
|
|
gcc versions can use evex512.
