Matching ConstantFPSDNode tablegen
...ating point constant literal match like:
%v = call <4 x float> @foo(i32 15, float %s, float 0.0, <8 x i32> %rsrc, <4
x i32> %samp, i1 0, i32 0, i32 0)
ret <4 x float> %v
def : XXXPat<(v4f32 (int_foo i32:$mask, f32:$s, 0, v8i32:$rsrc,
v4i32:$sampler, i1:$unorm, 0, i32:$cachepolicy)), (FOO_MI (COPY_TO_REGCLASS
?:$s, 32RegClass), ?:$rsrc, ?:$sampler, (as_i32imm ?:$mask), (as_i1imm
?:$unorm), (as_i1imm ?:$cachepolicy), (as_i1imm ?:$cachepolicy), 0, 0, 0, {

which would be ideal. This seems to be because OPC_CheckInteger only checks
for ConstantSDNode and not ConstantF...

lvm cache + qemu-kvm stops working after about 20GB of writes
...ed:
- The data in the cached LV has then not exceeded even half of the
space, so this should not happen. It even happens when only 20% of
cachedata is used.
- It seems to be triggerd most of the time when %cpy/sync column of `lvs
-a` is about 30%. But this is not always the case!
- changing the cachepolicy from cleaner to smq, wait (check flush ready
with lvs -a) and then back to smq seems to help /sometimes/! But not
always...
