Yes, this looks right. To be extra sure, ask Mercurial if it knows the file history:

$ hg log -f src/hotspot/cpu/aarch64/gc/shenandoah/c1/shenandoahBarrierSetC1_aarch64.cpp
$ hg log src/hotspot/cpu/x86/gc/shenandoah/c1/shenandoahBarrierSetC1_x86.cpp

...it should go back all the way to:

summary:     8214259: Implementation: JEP 189: Shenandoah: A Low-Pause-Time Garbage Collector
(Experimental)

I changed the synopsis for the bug to: "Shenandoah build fails with --with-jvm-features=-compiler1"
-- please change it for the changeset you are pushing.
