Hi,yujie:
When using this patch to compile test cases, ICE will be reported.

For those using my patch to build in gnu-versioned-namespace mode it
would be preferable not to have any failures when running testsuite.

Hi,
Even though we have had code to handle creation of indirect call graph
edges (so that these calls can than be made direct as part of IPA-CP
and inlining and eventually also inlined) for C++ member pointers for
many years, this code expects the member pointers to be structures
passed by value.
By default most patterns can be conditionalized on Arm targets. However
Thumb-2 predication requires the "predicable" attribute be explicitly
set to "yes". Most patterns are shared between Arm and Thumb(-2) and are
marked with "predicable". Given this sharing, it does not make sense to
use a

Hey everyone,
Here is the latest patchset of the Rust frontend, taken directly from our
development branch.
The patches have been built, tested and bootstrapped on x86-64.

I noticed while working on another patch that we had a duplicated
call to aarch64_process_target_attr.
Tested on aarch64-linux-gnu & pushed.

The sequence to commit a lazy save includes a branch based on
whether TPIDR2_EL0 is zero. The code assumed that CBZ could
be used for this, but that instruction is forbidden when
-mtrack-speculation is being used.
Tested on aarch64-linux-gnu & pushed.

In:
void bar() __arm_inout("za");
void foo() __arm_inout("za", "zt0") { bar(); }
foo cannot tail-call bar because foo needs to restore ZT0 after
the call. I'd forgotten to update the ok_for_sibcall rules
to handle this when adding SME2.
Thanks to Sander de Smalen for the spot.
Tested on
ACLE guarantees that a function like:
__arm_new("zt0") foo() { ... }
will start with ZT0 equal to zero. I'd forgotten to enforce that
after commiting a lazy save. After such a save, we should zero
ZA iff the function has ZA state and zero ZT0 iff the function
has ZT0 state.
Tested on
The main purpose of the aarch64_commit_lazy_save pattern
was to defer insertion of a half-diamond until splitting,
since splitting knew how to create the associated basic blocks.
However, the fix for PR113220 means that mode-switching also
knows how to do that. This patch therefore removes the
This patch fixes an ICE for a combination of:
- -fstack-clash-protection
- a frame that has SVE save slots
- a frame that has no GPR save slots
- a frame that has a VG save slot
The allocation code was folding the SVE save slot allocation into
the initial frame allocation, so that we had one

My earlier patch appears to have caused some regressions. I've taken a
quick look to see if there are obvious workarounds, but given the time
frame and the fact that I still don't really understand all the details
of how and when symbols get emitted, I felt it was safer to revert the
non-modules
In this PR, the SME mode-switching code needs to insert a stack-probe
loop for an alloca. This patch allows the target to do that.
There are two parts to it: allowing loops for insertions in blocks,
and allowing them for insertions on edges. The former can be handled
entirely within
Hi David.
This is OK.
Thank you, very nice stuff!
