--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Weird, at least on the current trunk when reverting all 4 i386.md hunks vs. all
but the 3_3 one I see differences in both
_Z22trx_undo_get_first_recRK11fil_space_tjtjRPK11buf_block_tP5mtr_tP7dberr_t
and
_ZL18trx_undo_free_pageP10trx_rseg_tbjjP5mtr_tP7dberr_t
So, are you sure it is the latter that matters?
There indeed is this shift + ior in
page_id_t(rseg->space->id,
page_no)
How many times is this function called?
What is rseg->space->id, hdr_page_no and page_no and what values receive the
buf_page_get_gen callees?
