[RISCV][NFC] Use enum types to improve debuggability (#188418)
So that we can see the enum values instead of integral values when
dumping in debuggers.
[libc][docs] Document libc-shared-tests ninja target (#189062)
Added a brief description of the libc-shared-tests target to the
Building and Testing page.
This target allows running tests for shared standalone components like
math primitives without the full libc runtime.
[Clang] [Sema] Don't diagnose multidimensional subscript operators on dependent types (#188910)
I forgot to check for dependent types in #187828; we somehow didn’t have
tests for this so CI didn’t catch this...
[MLIR][SCF] Fix loopUnrollByFactor for unsigned loops with narrow integer types (#189001)
`loopUnrollByFactor` used `getConstantIntValue()` to read loop bounds,
which sign-extends the constant to `int64_t`. For unsigned `scf.for`
loops with narrow integer types (e.g. i1, i2, i3), this produces wrong
results: a bound such as `1 : i1` has `getSExtValue() == -1` but should
be treated as `1` (unsigned).
Two bugs were introduced by this:
1. **Wrong epilogue detection**: the comparison `upperBoundUnrolledCst <
ubCst` used signed int64, so e.g. `0 < -1` (where ubCst is the
sign-extended i1 value 1) evaluated to false, suppressing the epilogue
that should execute the remaining iterations.
2. **Zero step after overflow**: when `tripCountEvenMultiple == 0` (all
iterations go to the epilogue), `stepUnrolledCst = stepCst *
unrollFactor` can overflow the bound type's bitwidth and wrap to 0. A
zero step causes `constantTripCount` to return `nullopt`, preventing the

[MLIR][XeGPU] Extend convert_layout op to support scalar type (#188874)
This PR adds scalar type to convert_layout op's result and operand. It
also enhance convert_layout pattern in wg-to-sg, unrolling, and
sg-to-lane distribution.
It is to support reduction to scalar, whether currently the layout
propagation doesn't support scalar to carry any layout. The design
choice to insert convert_layout op after reduction-to-scalar op to
record the layout information permanently across the passes.
[libc][docs] Fix POSIX basedefs links for nested headers (#188738)
Fix broken POSIX basedefs links for nested headers in llvm-libc docs.
The docgen script currently emits paths like `sys/wait.h.html`, but the
Open Group uses `sys_wait.h.html`, for example:
-
https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/sys_wait.h.html
This updates nested-header link generation while leaving flat headers
unchanged.
[lldb] Make single-argument Address constructor explicit (NFC) (#189035)
This is to highlight places where we (probably unintentionally)
construct an `Address` object from an already resolved address, making
it unresolved again.
See the changes in `DynamicLoaderDarwin.cpp` for a quick example.
Also, use this constructor instead of `Address(lldb::addr_t file_addr,
const SectionList *section_list)` when `section_list` is `nullptr`.
[mlir][vector] Add support for dropping inner unit dims for transfer_read/write with masks. (#188841)
The revision clears a long-due TODO, which supports the lowering when
transfer_read/write ops have mask via inserting a vector.shape_cast op
for the masked value.

[SLP][NFC] Reapply "Refactor to prepare for constant stride stores" (#188689)
Refactor to proceed #185964.
Much of this is a refactor to address this issues. Instead of iterating over one chain at a time, attempting all VFs for that given change, we now iterate over VFs, trying each chain for the current VF.
Includes fix for use after free bug.
[compiler-rt] Fix irrelevant warning on the builtins target (#189055)
Summary:
Currently, building through runtimes will yield this warning:
```
CMake Warning at compiler-rt/cmake/Modules/CompilerRTUtils.cmake:335 (message):
LLVMTestingSupport not found in LLVM_AVAILABLE_LIBS
Call Stack (most recent call first)
```
This is due to the fact that the builtins target does not go through the
s tandard runtimes patch and sets them as BUILDTREE_ONLY so they do not
show up. These are not used in this case, so just guard the condition to
suppress the warning.
[Offload][NFC] Various minor changes to Offload CMake (#189029)
Summary:
Most of these just remove some redundancy or rename `openmp` ->
`offload` where the variable is purely internal.
Produce back-references for anonymous namespaces (#188843)
The Microsoft mangle implementation does not produce back-references for
anonymous namespaces, which results in nonsensical output from both
`undname` and `llvm-undname`. Consider the following example:
```
namespace {
struct X {};
X foo(X, X);
}
int main() {
foo({}, {});
}

[Clang][OpenMP][NFC] Fix status color mismatches in OpenMPSupport.rst (#189050)
Correct the colors used in the OpenMP support tables so they
consistently match their status text:
- :good: (green) is for 'done' only
- :part: (yellow) is for in-progress states ('partial', 'worked on', 'in
progress', 'prototyped', etc.)
- :none: (red) is for 'unclaimed' only

[libc][bazel] Add generation for public headers (#184889)
Previously there was a single rule for stdbit, this PR adds generated
header targets for the rest of the linux headers. It also adds a
cc_library
for all of the public headers which also includes the types and macros
headers.
