Hi,
This patch checks if a constant is possible left/right cleaned on a rotated
value from a negative value of "li/lis". If so, we can build the constant
through "li/lis ; rldicl/rldicr".
Bootstrap and regtest pass on ppc64{,le}.
Is this ok for trunk?

Hi,
This patch checks if a constant is possible left/right cleaned on a rotated
value from a negative value of "li/lis". If so, we can build the constant
through "li/lis ; rldicl/rldicr".
Bootstrap and regtest pass on ppc64{,le}.
Is this ok for trunk or next stage1?
