Hi,
This patch checks if a constant is possible to be rotated to/from a positive
or negative value from "li". If so, we could use "li;rotldi" to build it.
Bootstrap and regtest pass on ppc64{,le}.
Is this ok for trunk?

In English the word
Hi,
This patch checks if a constant is possible to be rotated to/from a positive
or negative value from "li". If so, we could use "li;rotldi" to build it.
Bootstrap and regtest pass on ppc64{,le}.
Is this ok for trunk or next stage1?
