[Qemu-devel] [PATCH 0/3] target-arm: more UNDEF/UNPREDICTABLE fixes

[Peter Maydell <peter.maydell@linaro.org>]

This patchset is a final chunk of fixes to UNDEF and UNPREDICTABLE
cases; this lot were flushed out by doing a brute-force exercising
of the decoder on all possible input instruction values. (There
are some remaining issues I identified with that check, but they are
all of the form "complains about TCG temp leak on a code path where
we're going to UNDEF anyway", so not actually harmful. I'll post
patches for those later on, but I wanted to get the important ones
out first.)

Since they're basically fixes for bugs where guest code can make
qemu fall over or overrun a buffer, I think they're a good candidate
for putting into 0.15...

Peter Maydell (3):
  target-arm: Handle UNDEF and UNPREDICTABLE cases for VLDM, VSTM
  target-arm: UNDEF on a VCVTT/VCVTB UNPREDICTABLE to avoid TCG assert
  target-arm: Don't print debug messages for various UNDEF cases
