Subject: [PATCH] x86: correct CPU_AMX_{BF16,INT8}_FLAGS
Date: Mon, 17 Oct 2022 09:44:51 +0200	[thread overview]
Message-ID: <19c08747-fa5b-1e67-3dd2-c891a2c0c1fa@suse.com> (raw)

AMX-TILE is a prereq to these, as already correctly expressed by
CPU_ANY_AMX_TILE_FLAGS. Express the dependency also in the reverse
("positive") direction.
---
Ideally we would teach i386-gen to at least check (better derive) such
two-way dependencies.
