--- Comment #2 from Jeffrey A. Law <law at gcc dot gnu.org> --- We shouldn't use Zba just for the sake of using Zba; it needs to be profitable. The folks doing the analysis behind this BZ are only looking at instruction counts -- they're not really thinking about uarch stuff or even code size, though I think having them look at the latter in addition to dynamic counts should be possible.
