[RISCV][NewPM] Port RISCVCodeGenPrepare to the new pass manager (#168381)
As suggested in the review for #160536 it would be good to follow up and
port the RISC-V passes to the new pass manager. This PR starts that
task. It provides the bare minimum necessary to run RISCVCodeGenPrepare
with opt -passes=riscv-codegenprepare. The approach used is modeled on
my observations of the AMDGPU backend and the recent work to port the
X86 passes.
The testing approach is to add a `-passes=riscv-foo` RUN line to at
least one test, if an appropriate test exists.
ELF,test: Test unversioned undefined symbols of index 0 and 1
My 2020 change that added versioned symbol recognition
(reviews.llvm.org/D80059) checks both VER_NDX_LOCAL and VER_NDX_GLOBAL,
though test coverage was missing. lld/test/ELF/dso-undef-extract-lazy.s
checks that the undefined symbol is indeed considered unversioned.
Limit catalog sync jobs queue depth limit to 1
This commit adds changes to limit catalog sync jobs queue depth limit to 1 as that should be sufficient in terms of making sure that the catalog is synced properly.
[libc] Fix -Wshorten-64-to-32 in fileop_test. (#168451)
Explicitly cast 0 to size_t type to match fread() return type. This
follows the pattern used elsewhere in this file, and fixes
-Wshorten-64-to-32 warnings when building the test.
[orc-rt] Simplify Session shutdown. (#168664)
Moves all Session member variables dedicated to shutdown into a new
ShutdownInfo struct, and uses the presence / absence of this struct as
the flag to indicate that we've entered the "shutting down" state. This
simplifies the implementation of the shutdown process.
[MLIR][XeGPU] Allow create mem desc from 2d memref (#167767)
This PR relax the create_mem_desc's restriction on source memref,
allowing it to be a 2d memref.
[libclc] Use CLC atomic functions for legacy OpenCL atom/atomic builtins (#168325)
Main changes:
* OpenCL legacy atom/atomic builtins now call CLC atomic functions
(which use Clang __scoped_atomic_*), replacing previous Clang __sync_*
functions.
* Change memory order from seq_cst to relaxed; keep device scope (spec
permits broader than workgroup). LLVM IR for _Z8atom_decPU3AS1Vi in
amdgcn--amdhsa.bc:
Before:
%2 = atomicrmw volatile sub ptr subrspace(1) %0, i32 1
syncscope("agent") seq_cst
After:
%2 = atomicrmw volatile sub ptr subrspace(1) %0, i32 1
syncscope("agent") monotonic
* Also adds OpenCL 1.0 atom_* variants without volatile on the pointer.
They are added for backward compatibility.
[LV]: Skip Epilogue scalable VF greater than RemainingIterations. (#156724)
Consider skipping epilogue scalable VF when they are greater than
RemainingIterations same as fixed VF.
And skip scalable RemainingIterations from that comparison because
SCEV ATM can't evaluate non-canonical vscale-based expressions.
Remove MCX_MAX_QUEUES, which was just an arbitrary number we picked, and
instead use IF_MAX_VECTORS for arrays and doorbell layout checks, and
account for the maximum number of EQs from the device capabilities when
determining how many queues to use.

Reapply "[Github] Update PR labeller to v6.0.1 (#167246)"
This reverts commit d772663a9f003a08ee76414397963c58e80b27d7.
This fixes the final issue with the labeller landing. There were
two remaining issues:
1. There was an extra quote on one of the globs
2. Some of the yaml keys were named incorrectly (should have been
plural)
[PowerPC] Add custom lowering for SADD overflow for i32 and i64 (#159255)
This patch improves the codegen for saddo on i32 and i64 in both 32-bit
and 64-bit modes by custom lowering. It implements signed-add overflow
detection using the `(x eqv y) & (sum xor x)`bit-level sequence.
powerpc: Don't use cache to zero pages
pmap_zero_page() may be called on uncached pages, so using the cache to
zero uncached pages may trigger a fault.

nvme: Notify namespace changes better
When we get a namespace notification, we have to reconstrut the
namespace to get the new identification data from the namespace. For
each namespace in the AEN, we will reconstrict it before we call the
notification. We also flag it as changed for the duration of the change
callback (prior versions of the patch needed to keep track, but we no
longer do, so this bit may be removed). Note when we've seen the
namespace so we can notify when it goes away.

nda: React to namespace change events
Register for AC_GETDEV_CHANGED. When we receive a namespace
notification, we only create a new device if it was unconfigured. If it
was configured, generate this async event. Rely on the fact that we
reconstruct namespace to just get the data from the identify data and
call disk_resised.

nvme: Fix backwards sense of error condition
b21e67875bf0c tested for the good condition, not the error condition, so
we'd never do anything else in this function. This was causing certain
logging not to happen, and also prevented forthcoming namespace size
change code from working as well.
