[PATCH 14/14] tests/tcg: ARC: Add TCG instruction definition tests


From: cupertinomiranda
Subject: [PATCH 14/14] tests/tcg: ARC: Add TCG instruction definition tests
Date: Wed, 30 Sep 2020 21:46:04 +0100

From: Claudiu Zissulescu <claziss@synopsys.com>

The added tests verify basic instructions execution as well
as more advanced features such as zero overhead loops interrupt
system, memory management unit and memory protection unit.
