[LLDB][NativePDB] Create typedefs in structs (#169248)
Typedef/using declarations in structs and classes were not created with
the native PDB plugin. The following would only create `Foo` and
`Foo::Bar`:
```cpp
struct Foo {
struct Bar {};
using Baz = Bar;
using Int = int;
};
```
With this PR, they're created. One complication is that typedefs and
nested types show up identical. The example from above gives:
```
0x1006 | LF_FIELDLIST [size = 40, hash = 0x2E844]
- LF_NESTTYPE [name = `Bar`, parent = 0x1002]
- LF_NESTTYPE [name = `Baz`, parent = 0x1002]

[XRay][test] Mark fdr-mode.cpp test as unsupported for RISC-V
Commit c6f501d479e8 fixed an issue where some tests were incorrectly
marked as unsupported for a bootstrapping build. This exposed in our
'slow' full-bootstrap qemu-system CI that the fdr-mode.cpp fails on
RISC-V. We mark it as unsupported. I believe _xray_ArgLoggerEntry needs
to be implemented in xray_trampoline_risc*.S for this to work.
[X86] combineVectorSizedSetCCEquality - ensure the load is a normal load (#172212)
Noticed while trying to replace the IsVectorBitCastCheap helper with
mayFoldIntoVector (still some work to do as we have a number of multiuse
cases) - technically its possible for a extload to reach this point.
[ARM] Introduce intrinsics for MVE fp-converts under strict-fp. (#170686)
This is the last of the generic instructions created from MVE
intrinsics. It was a little more awkward than the others due to it
taking a Type as one of the arguments. This creates a new function to
create the intrinsic we need.
[ARM] Introduce intrinsics for MVE vcmp under strict-fp. (#169798)
Similar to #169156 again, this adds intrinsics for strict-fp compare nodes to
make sure they end up as the original instruction.
[ARM] Introduce intrinsics for MVE vrnd under strict-fp. (#169797)
Similar to #169156 again, this adds intrinsics for strict-fp vrnd nodes to make
sure they end up as the original instruction.
[LLVM][Examples] Disable broken JIT + plugin tests (AIX, Sparc)
Plugins appear to be broken on AIX, CI fails. There is logic in
CMakeLists for plugins+AIX, but it was never tested before...
Note: when plugins work, also enable tests in Examples/IRTransforms.
There's no Sparc support for JIT tests, so disable the JIT tests in the
examples (copied from ExecutionEngine/lit.local.cfg).
[DAG] SDPatternMatch - Replace runtime data structures with lengths known at compile time (#172064)
Following the suggestions in #170061, I replaced `SmallVector<SDValue>`
with `std::array<SDValue, NumPatterns>` and `SmallBitVector` with
`Bitset<NumPatterns>`.
I had to make some changes to the `collectLeaves` and
`reassociatableMatchHelper` functions. In `collectLeaves` specifically,
I changed the return type so I could propagate a failure in case the
number of found leaves is greater than the number of expected patterns.
I also added a new unit test that, together with the one already present
in the previous line, checks if the matching fails in the cases where
the number of patterns is less or more than the number of leaves.
I don't think this is going to completely address the increased compile
time reported in #169644, but hopefully it leads to an improvement.
[libc++] Use native wait in std::barrier instead of sleep loop (#171041)
For some reason, the current `std::barrier`'s wait implementation polls
the underlying atomic in a loop with sleeps instead of using the native
wait.
This change should also indirectly fix the performance issue of
`std::barrier` described in
https://github.com/llvm/llvm-project/issues/123855.
Fixes #123855
[clangd] Add a (currently hidden) --strong-workspace-mode flag (#172160)
Its current effect is to use the `rootUri` provided by the client as the
working directory for fallback commands.
Future effects will include other behaviors appropriate for cases
where clangd is being run in the context of editing a single
workspace, such as using the `compile_commands.json` file in the
workspace root for all opened files.
The flag is hidden until other behaviors are implemented and they
constitute a cohesive "mode" for users.
Original PR in #155905, which was reverted due to a UBSan failure
that is fixed in this version.
[ARM][AArch64] Replace ".f16(bfloat" with ".bf16(bfloat" in intrinsics. NFC
It looks like these were copied from fp16 tests, and forgot to update the
intrinsic types. Also remove some old definitions that are no longer required.
Revert "[X86][APX] Add pattern for zext(X86setcc ..) -> SETZUCCr (#170806)" (#172192)
This reverts commit 2612dc9b5faeaeb180c5a5e0c282642faef8891b but keeps
`Predicates = [HasNDD]` removed.
There are two issues identified related to the change. One is
INSERT_SUBREG cannot guarantee source and dest to be the same register.
It mostly happens on O0. The other one is zero_extend is not a chain
node, as a result, we will lose the chain for SETZUCCr.
[MLIR][Python][Transform] Print diagnostics also upon success (#172188)
If we do not collect the diagnostics from the
CollectDiagnosticsToStringScope, even when the named_sequence applied
successfully, the Scope object's destructor will assert (with a
unhelpful message).
[clang-tidy][NFC] Remove obsolete FIXME comment (#172120)
This comment was written 12 years ago. It's no longer correct to say
that diagnostic reporting is under heavy development, and we seem to be
doing just fine without tablegenned IDs, so I think we can simply remove
it.
[clang][PAC] add support for options parameter to __ptrauth
This PR adds support for an 'options' parameter for the __ptrauth
qualifier.
The initial version only exposes the authehntication modes:
* "strip"
* "sign-and-strip"
* "sign-and-auth"
We also support parsing the options but not yet the implementation
* "isa-pointer"
* "authenticates-null-values"
The initial support for authentication mode controls exist to support
ABI changes over time, and as a byproduct support basic initial tests
for option parsing.
