The split in ssse3_pshufbv8qi3 forces a const vector into the constant
pool, and loads from it. That runs after reload, so if the load
requires any reloading, we're out of luck. Indeed, if the load
address is not legitimate, e.g. -mcmodel=large, the insn is no longer
recognized.

Hi,
As Segher and Mike pointed out, the define_insn_and_split should avoid
to use empty split condition if the condition for define_insn isn't empty,
otherwise it can sometimes leads to unexpected consequence.
This patch is to fix some places like this.

Hi,
this patch updates costs of integer divides to match actual latencies (the
scheduler model already does the right thing). It is essentially no-op, since
we end up expanding idiv for all sensible constants, so this only may end
