Subject: [PATCH], Patch #10 of 10, Add pc-relative tests
Date: Thu, 15 Aug 2019 03:48:00 -0000 [thread overview]
Message-ID: <20190814231658.GJ16578@ibm-toto.the-meissners.org> (raw)
In-Reply-To: <20190814205732.GA11956@ibm-toto.the-meissners.org>
This patch adds tests to make sure the appropriate pc-relative instructions are
generated for -mcpu=future.
The tests in this patch all pass with patches 1-7 applied on a little endian
power8 system running Linux. Once patches 1-7 have been applied, can I check
these patches into the trunk?
2019-08-14 Michael Meissner <meissner@linux.ibm.com>
