Subject: [PATCH] Add ARCv2 ISA processors support to Zero
|
|
|
|
This adds ARCv2 processors support in OpenJDK via
|
|
"Zero Assembly Project" (see https://openjdk.java.net/projects/zero).
|
|
|
|
That' a purely interpretive mode, so likely not that fast
|
|
as JIT'ed version, but for starters it's much better than nothing.
|
|
|
|
Once all the logistical problems are solved hopefully this
|
|
change will be accepted upstream.
