* load_multiple for argument push!?

Hi,

I am wondering if gcc supports "load_multiple" for multiple argument
push.  Looking at arm.md and mcore.md, their load_multiple seem to be
useful as such, but I don't see any "load_multiple" in calls.c.

Does anybody have a clue on this?

Thanks,

Kazu Hirata

Well, I submitted such a patch for the h3800 target.  Then Jeffery Law
suggested that I shuold make use of store_multiple.  This is why I am
wondering if gcc supports it for argument push.

By the way, I should have said "store_multiple", because load_multiple does
not write anything to memory. :-)

Thanks,

You can define a peephole to coalesce multiple pushes / stores into one.
