Hi Stam,
The arm parts look sensible but we'd need review for the df-core.h
and df-core.cc changes.
Maybe Jeff can help or can recommend someone to take a look?

Hi all,
This is the 2/2 patch that contains the functional changes needed
for MVE Tail Predicated Low Overhead Loops. See my previous email
for a general introduction of MVE LOLs.
This support is added through the already existing loop-doloop
mechanisms that are used for
x27;s fastmodels.
Ok for trunk?
Thanks,

In this one also 'is a MVE instruction that is VPT-predicable' would
be better I think.
Oops, thanks for spotting.

Assumes single_set doesn't return 0.
Thanks! That is indeed correct.
Corrected this by having a utility function to scan insn operands and
check against mve_memory_operand that supports any number of
operands/SETs in the insn

Hi all,
We've recently sent up a lot of patches overhauling the testsuite of the
Arm MVE backend.
With these changes, we've also identified and fixed a number of bugs
(some backend bugs and many to do with the polymorphism of intrinsics in
MVE the header file).
These would all be relevant to

Indeed! I'm building up a larger list of commits that we're hoping
to backport, so I will include this on that list.

Hi all,
This is just a minor issue I found with a previous test
of mine that caused it to fail in C++ mode due to these
unused const variables being uninitialised. I forgot to
remove these after removing some test cases that did use
them.
I removed the test cases, because I came to the
conclusion
