From 6187ec05edc240204935fdf0d89cded563fdeab4 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 19 Dec 2018 12:26:20 +1100 Subject: target/ppc: Remove silly GETFIELD/SETFIELD/MASK_TO_LSH macros The (only) obvious use for these macros is constructing and parsing guest visible register fields. But the way they're constructed, they're only valid when used on a *host* long, whose size shouldn't be visible to the guest at all. They also have no current users, so just get rid of them.
