------- Comment #28 from chrbr at gcc dot gnu dot org 2010-02-03 08:30 ------- Hello Kaj, thanks for your proposal
thanks for the proposal. but I'm wondering if preventing the scheduling of the mov.l and mova instructions are not too much overkill ? (sh_reorg comes after the scheduler, but even if it didn't that should be ok to mov up instructions. (the R0 liverange between the add and load is another more general problem) Do I miss something ? We only want to avoid the CP to be inserted between those 2 instructions, it's not necessary to have more blockages. I'm working on something that tracks the GOT loading access during the find_barrier walk and then revert back at the end to the latest safe place. OK on the example but the full linux distrib rebuild and validation is still ongoing. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42841
