Confirmed. TLS code sequences consist of address generation followed by
address dereference, for all TLS models. The address generation part uses
UNSPECs because we need to differentiate the addis/addi from other hi/lo_sum
patterns: The TLS versions need to emit reloc specifiers. Existing combined
patterns cannot be used.
To fix this problem, the rs6000 backend needs to be taught how to combine the
lo_sum lookalike part of the TLS address generation with the TLS load/store. I
would guess that the easiest way to implement this is with new peephole2
patterns.
