Subject: [PATCH], Patch #9 of 10, Add tests with large memory offsets
Date: Wed, 14 Aug 2019 23:17:00 -0000 [thread overview]
Message-ID: <20190814231345.GI16578@ibm-toto.the-meissners.org> (raw)
In-Reply-To: <20190814205732.GA11956@ibm-toto.the-meissners.org>
This patch adds tests for all of the types using large address offsets that
would not fit into 16 bits, and verifies that prefixed instructions are generated.
The tests in this patch all succeed when patches 1-7 are applied on a little
endian power8 system. Can I check these patches into the trunk when the
previous patches have been applied?
2019-08-14 Michael Meissner <meissner@linux.ibm.com>
