Hi David, 
I guess "not including C1 or C2 in a build (ie interpreter-only)" refers to the zero build. 
Yes. Regarding zero build, these source files fixed in this patch would not be compiled.

However, the build failures this patch aimed to address are 'server build without C1 feature' and 'server build without C2 feature'.
'C1/C2' in the title of this PR means 'build without C1' or 'build without C2'.

As stated in JDK-8258856, the build failures can be reproduced by 
` ./configure --with-jvm-features=-compiler1 && make images`
and ` ./configure --with-jvm-features=-compiler2 && make images` respectively.

Hope that I made myself understood. Thanks.
Hao
