Subject: [PATCH 0/3] target/arm: Complete ISS for MTE tag check fail
Date: Wed, 12 Aug 2020 10:19:43 -0700	[thread overview]
Message-ID: <20200812171946.2044791-1-richard.henderson@linaro.org> (raw)

As reported by Andrey, I was missing the complete ISS info for
the Data Abort raised upon a synchronous tag check fail.

The following should fix that.  All the twisty little rules for
the ISS.ISV bit are already handled by merge_syn_data_abort.
Probably the most important bit that was missing was ISS.WnR,
as that is independent of ISS.ISV.

Andrey, will you please test?
