Hi,
Resending. I did not get any responses the last two times and I too
forgot about it. Can someone please review this?

Thanks! I see the last sentence could do with better
punctuation, so I added the obvious comma. Installed as

Any PR's you open related this this, copy me on them and I'll try to get
them addressed.
I could separate the issues I saw into PRs 54003-6. That's all,
hopefully ...at least for now. :)
BTW, your @gcc.gnu.org

These were spotted while debugging usage of atomics within
glibc. The kind of changes are microoptimizations,
nanooptimizations, a buglet and a major issue. Micro: the
load-store-conditional sequence for compare-and-swap I
originally committed was an earlier version improved later.
Use the new need_atomic_barrier_p.

Buglet in atomic_compare_and_swapmode, allowing (in theory)
a volatile or post-increment memory operand. Simplest and
safest fixed by excluding all memory operands.
gcc:
* config/cris/sync.md (atomic_compare_and_swapmode): Change
predicate to nonmemory_operand for operand 3. Add
Microoptimizations for the atomic patterns themselves. Constant
operands are so common that it seems wasteful not to handle the
most common cases and avoid wasting a register.

Well, give up by default that is, and fix it up in a helper

the duration. (Sorry!) Yes, this means that
fold_builtin_atomic_always_lock_free is wrong. It knows about
alignment in general but doesn't handle the case where the

Buglet in cris_preferred_reload_class, incidental, apparently
without effect at least regarding failing test-cases. A class
disjunct from the input was returned as preferred. It could
arguably be gcc_asserted as a sanity-check by the caller that
the returned class is a subset of the original
I think CONSTANT_ADDRESS_P can and should be eliminated,
replaced by something like
CONSTANT_P (x) targetm.legitimate_address_p (QImode, x, false)
(or QImode replaced by the known used mode) in the code
currently calling it.
It should, because the default definition is redundant and evil;
