One nit; the prototype of the new function:
extern void get_implicit_reg_pending_clobbers (rtx_insn *, HARD_REG_SET *);
has source operand on the left, destination on the right; it's probably nicer
to swap them around.
OK as far as selective scheduler changes go, but this also needs a general
scheduler maintainer ack for the sched-deps.c change. Vladimir, can you have
a look?
Thanks.
Alexander
