superscalar: allow speculative instructions #2278

Closed cathales closed 1 week ago

cathales commented 1 week ago

Allow an instruction following a branch to be issued with the branch (before the branch is resolved, so the instruction is speculative).

Speculative loads are disabled for now, we are working on a solution for speculative non-idempotent loads.

Speculative stores are disabled until we find evidence that it increases performance.
