Subject: [Qemu-devel] ARM: SVE while issue
Date: Tue, 31 Jul 2018 15:52:53 +0200	[thread overview]
Message-ID: <CABoDooME+KJVWJQcodVC-Mo2qpZhmYA3LVBLQcTj88qW1i5h5g@mail.gmail.com> (raw)

Hello Richard,

according to SVE specification, whilels/whilele instructions have a
special case where if the second operand is the maximum (un)signed
integer then the result is an all-true predicate.  The current code in
trans_WHILE doesn't seem to capture that requirement.  I'm afraid the
fix won't be as trivial as for the other two bugs I reported :-)

Thanks,

Laurent
