> These patches add aarch64-linux support to the two versions of JamVM, a
> compact Java virtual machine, used during Guix's Java-bootstrap process (see
> the comment near the top of gnu/packages/java.scm).
>
> With them applied the process gets as far as starting to build the first
> IcedTea package (version 1.13.13), though this eventually fails with an error
> from gcc while compiling the Hotspot JVM (unrelated to my changes as far as I
> can tell). I'm still working on this issue.
>
> Note I have found it unnecessary to use older versions of gcc and glibc when
> building JamVM 1.5.1 on AArch64; the CPU's instruction cache is flushed
> explicitly on this platform so it shouldn't be possible for the "invalid
> instruction" situation mentioned in a comment to develop, and I haven't seen
> it myself.
>
> The "opcode guard" patch is necessary for floating-point operations to work
> correctly when JamVM is built with stack-caching enabled, as it is by default
> on AArch64 and elsewhere.
>
> Finally, I've renamed the existing "jamvm-arm.patch" file to
> "jamvm-1.5.1-arm.patch" for clarity as there are now separate patchsets for
> each JamVM release.
