Subject: [PATCH] skip patchable_function_entry tests on ia64
Date: Fri, 11 Aug 2017 12:42:00 -0000	[thread overview]
Message-ID: <20170811103429.5vmf4hlpox5abxnu@suse.de> (raw)
In-Reply-To: <B3ACC0F7-B23C-428B-95BF-A5AA853C1208@linaro.org>

As Andreas found out, patchable_function_entry tests generate false failures
on ia64. On a closer look, this feature needs some more thought on itanium:
I *could* imagine it is a good idea to generate N complete nop "bundles",
which would be properly aligned and allow for easy replacement with alternate
binary code.

But I'd rather leave this to the platform experts, or whoever comes up with
a good use case, to implement the proper cpu override hook. Meanwhile, as
long as the expected results remain undefined, disable the tests.

	Torsten
