I don't know. It's difficult for me to guess whether a dependency chain like
val -> xor -> xor
(3 insns with serial dependencies) is better than
val --> xor
load -/
(3 insns, but only

This reverts 829e1376d940 ("tcg/s390: Introduce TCG_REG_TB"), and
several follow-up patches. The primary motivation is to reduce the
less-tested code paths, pre-z10. Secondarily, this allows the
unconditional use of TCG_TARGET_HAS_direct_jump, which might be more
important for performance than an
