Hi,
when turning a tail-recursive call into a loop, the tail-call pass
creates a phi node for each gimple_reg function parameter that has any
use at all, even when the value passed to the original call is the same
as the received one, when it is the parameter's default definition.
This results in

As usual with costing changes, the patch exposes latent problem. The

We currently use default mid-end expanders for logical DImode operations.
These split operations without first splitting off complex immediates or
