src/cpu/sparc/vm/sparc.ad:

+instruct encodeKlass_not_null(iRegN dst, iRegP src) %{
+  format %{ "encode_heap_oop_not_null $src, $dst" %}

+instruct decodeKlass_not_null(iRegP dst, iRegN src) %{
+  format %{ "decode_heap_oop_not_null $src, $dst" %}

Copy-paste typo:  oop should be klass.

src/cpu/x86/vm/x86_64.ad:

+instruct storeImmNKlass(memory mem, immNKlass src)
...
+  ins_encode %{
+    address con = (address)$src$$constant;
+    __ set_narrow_klass($mem$$Address, (Klass*)$src$$constant);
+  %}

con is unused.

I haven't reviewed all files yet but I'm working on it...
