Revert "[libc] Support %lc in printf (#169983)"
This reverts commit 1327c50ef199b481f5326cf6ca3710fc111b70b1.
The printf headers are intended to be header-only, this introduces
external symbol dependencies.
Use setExprNeedsCleanups in BuildCXXNew and avoid breaking c++98
This approach is much cleaner, but broke checkICE reporting in c++98.
Stepping through a debugger shows that this happend because the
static_assert test didn not recognize ExprWithCleanups as transparent to
constant evaluation. To addresse this, we update CheckICE to recurse
into the sub-expression, and keep the old behavior.
[MC/DC] Refactor MCDCCoverageBuilder. NFC. (#125409)
- Get rid of the old `DecisionStack` and dissolve it into push/pop
`CurCondIDs` in `VisitBin`, since `VisitBin` is recursive.
- Introduce the new `DecisionStack` with `DecisionState` to handle the
current `Decision` in nested `Decision`s.
- The stack has the sentinel that has `DecisionExpr = nullptr`.
- Split out `checkDecisionRootOrPush` from `pushAndAssignIDs` for
non-BinOp. It assigns `CondID` to `E` (instead of assignment LHS in
`pushAndAssignIDs`).
- The stack is manupilated at the top Decision operator in `VisitBin`.
- The stack grows at the entrance of the Decision with the initial
state.
- In the same level in `VisitBin`, the stack is popped and the
`Decision` record is emitted.
- Introduce `DecisionEndToSince` to sweep `MCDCBranch`es partially in
`cancelDecision`.
Use scsi_io_get rather than nvme_ccb_get for passthrough commands, so we'll
sleep if there are no ccbs available, avoiding a panic that mlarkin@ ran into.
While here, take the rwlock around passthrough commands that come in through
the scsi ioctl path for consistency with the bioctl path.

[CIR] Upstream CIR method attribute handling (#174640)
This adds code for generating cir.method attributes and lowering them to
LLVM IR to implement support the C++ method pointer variables.
[OpenCL] Set KHR extensions minimum version to OpenCL 1.0 (#175120)
Motivation is similar to 25cfdaa4e9dc. Their spec don't specify a
required OpenCL version. Targets may expose them before OpenCL 1.2.
Set KHR extensions (depth images, mipmaps, subgroups, kernel clock, dot
product, ext_float_atomics, extended_bit_ops, cles_khr_int64) to
availability 1.0.
Changes to opencl-c.h:
* Relax header and test guards to allow extension macros whenever any
OpenCL C version is defined.
* Relax cl_khr_depth_images guard to allow cl_khr_depth_images, OpenCL
C++, or OpenCL C 2.0+, since image2d_depth_t and image2d_array_depth_t
types require that coverage.
* Guard image1d_t, image1d_array_t and image2d_array_t types with OpenCL
C++ or OpenCL C 1.2+ to match with OpenCL C spec.

[lldb] Change po fallback messaging (#175847)
When an object description expression fails, instead of emitting an error, mark it as a
warning instead. Additionally, send the more low level details of the failure to the
`expr` log, and show a more user friendly message:
> `po` was unsuccessful, running `p` instead

vt(4): allow up to _SIG_MAXSIG (128) for VT_SETMODE
VT_SETMODE ioctl currently checks the provided signal numbers with its
own ISSIGVALID macro that uses NSIG (32) as a maximum, although the code
that will actually send the signal in sys/kern/kern_sig.c uses
_SIG_VALID which allows up to _SIG_MAXSIG (128).
This change aligns the vt code with the kernel internals and enables the
use of higher signal numbers so that applications are not limited to
SIGUSR1 and SIGUSR2 for vt release and acquire signals.
