[RISCV][llvm-readobj,llvm-objdump] Use getRISCVVendorRelocationTypeName for RISCV vendor relocations (#172811)
Use getRISCVVendorRelocationTypeName to resolve RISCV vendor-specific
relocation names (R_RISCV_CUSTOM192-255) when preceded by
R_RISCV_VENDOR.
This improves the output of llvm-readobj and llvm-objdump to show
vendor-specific names like R_RISCV_QC_ABS20_U, R_RISCV_QC_E_BRANCH
(QUALCOMM) and R_RISCV_NDS_BRANCH_10 (ANDES) instead of generic
R_RISCV_CUSTOM* names.
Per RISC-V psABI, R_RISCV_VENDOR must be placed immediately before its
associated vendor-specific relocation, so the vendor symbol is consumed
after one use. Unknown vendors fall back to R_RISCV_CUSTOM*.
[libc++][NFC] Refactor `[[nodiscard]]` tests (#173451)
Originally some `[[nodiscard]]` tests were implemented in
`*/test/libcxx/diagnostics`. The Standard has a library `Diagnostics`
and this folder should be reserved for it by convention. Most newer
tests were added to their respective sub-folders. This patch moves
around the already implemented `[[nodiscard]]` tests to their respective
folders where they belong and standardizes the name to
`nodiscard.verify.cpp` wherever possible.
N.B. This refactors only tests, which were merged. The remaining
(in-progress) ones will be moved in a future patch to reduce merge
conflicts.
[clang-doc] Add a border box to comments in HTML (#174541)
Comments weren't very visually distinctive in HTML. They immediately
proceeded the declaration header and didn't have spacing between them.
To visually organize them, they now have a thin border around them.
Different comment types are also now separated by a small gap. This also
allows them to be easily changed in the future. Some extraneous `<div>`
tags are also removed or merged.
[LV] Conservatively predicate SDiv/SRem (#170818)
Conservatively predicate sdiv/srem:
- RHS may carry poison in masked‑off lanes.
- RHS could be −1 while LHS has masked‑off lanes (risking INT_MIN/−1
overflow).
We’ll relax this once we can prove non‑wrap/non‑poison conditions.
Fixes #170775.

[AMDGPU] Handle `s_setreg_imm32_b32` targeting `MODE` register
On certain hardware, this instruction clobbers VGPR MSB `bits[12:19]`, so we need to restore the current mode.

[RISCV] Improve load/store pairing for Xqcilsm instructions in RISCVLoadStoreOptimizer (#174612)
If we did not pair two viable `Xqcilsm` load/store instructions in
`RISCVLoadStoreOptimizer` we iterated over the second instruction when
looking for other pairs to merge. This leads to us missing out on
opportunities where the second instruction could have been the start of
another potential pair that could have been merged.
stdbool.h: Update for C23
When a compiler with C23 or higher is detected, builtin bool, true,
and false are used to conform the C23 standard.

[libclc] Add support for `nvptx64-nvidia-cuda` triple (#174611)
Summary:
The OS here is the standard CUDA support target, which is the ABI used

aliases asn `cuda` in the triple is the canonical form for most all GPU

[lldb] Update LLDB DAP documentation. (#172580)
This adds a new page to lldb.llvm.org that includes a user guide for
lldb-dap.
The overall structure for documentation:
* https://lldb.llvm.org/resources/lldbdap.html - represents the user
facing documentation for lldb-dap, a high level overview of lldb-dap and
a place we can point users to for basic usage information.
* https://lldb.llvm.org/resources/lldbdap-contributing.html - represents
the contributing documentation for lldb-dap.
* llvm-project/lldb/tools/lldb-dap/README.md - The lldb-dap VSCode
Extension specific documentation.
This is a first pass at the documentation, I expect to expand on it
further as needed.
security/zoneminder: Patch mismatches between format specifier and types
Variously the issues are time_t, size_t, suseconds_t.
With this, there are no format warnings on amd64 or i386.
