+Subject: [PATCH 1/3] build/meson: remove duplicated lib prefix from internal
+ static asm lib
+
+For consistency, this avoids generating `liblibass_asm.a`. Meson adds
+lib prefix automatically when needed.

+Subject: [PATCH 2/3] build/meson: link missing asm lib for checkasm/compare
+ tools
+
+On aarch64 target, asm code is compiled into internal static library
+`asm_lib`. This hasn't been linked after changing to extract_all_objects.
