--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> --- There is a general question if we shouldn't give up in can_increase_alignment_p for all DECL_THREAD_LOCAL_P vars because increasing their alignment doesn't mean just a few wasted bytes per process due to the alignment, but a few wasted bytes per thread (TLS space is or should be far more space constrained than normal data or rodata sections). But even if we do that, the question is if alignas(16) thread_local vars etc. work on Solaris.
