FWIW, I (locally) solved the problem of absolute path names in the compiled assembly by adding the `.file` directive. For example:

--- a/src/hotspot/os_cpu/linux_aarch64/atomic_linux_aarch64.S
+++ b/src/hotspot/os_cpu/linux_aarch64/atomic_linux_aarch64.S
@@ -19,7 +19,7 @@
 // or visit www.oracle.com if you need additional information or have any
 // questions.

-
+        .file "atomic_linux_aarch64.S"

         .text
