OSType with less than 8 bytes has special code that isn't tested yet.
The same for C-strings that don't have `const char *` type. Also we're now testing
escaping the ASCII escape sequence (\033).
Summary:
https://reviews.llvm.org/D82029 introduced the non-throw check for final_suspend(). There are a few tests I missed in that patch.
Fixing them here.

Set the correct os type in the arch triple when running macOS.
Debugserver currently always assumes macOS == x86_64. This patch
generalizes the support to make sure it works on a different
architecture.

Summary:
In order to enable mass testing of opt under NPM, specifically passes
specified via -foo-pass.
This is gated under a new opt flag -enable-new-pm. Currently
the pass flag parser looks for legacy PM passes with the name "foo" (for
opt arg "-foo") and creates a PassInfo for each one. Here we take the
(legacy PM) pass name and try to match it with one defined in (NPM)
PassRegistry.def. Ultimately if we want all tests to pass like this,
we'll need to port all passes to NPM and register them in
PassRegistry.def under the same name as they were reigstered in the
legacy PM.
Maybe at some point we'll migrate all -foo to --passes=foo, but that
would be after the NPM switch.
Flipping on the flag causes 2XXX failures under check-llvm. By far most
of them are passes either not ported to NPM or don't have the same name
in PassRegistry.def as their old name.

WithColor.h is one of the most common headers, we can severely reduce its frontend impact (in ClangBuildAnalyzer reports) by removing the bulky CommandLine.h include, forward declaring llvm:🆑:OptionCategory and just including raw_ostream.h instead.
Add support for changing the stdout and stderr file in Lua's I/O library
and hook it up with the debugger's output and error file respectively
for the interactive Lua interpreter.

This patch adds a new cli argument to the automation script to generate
a report of the current SPIRV spec instruction coverage. It dumps to the
standard output a YAML string with the coverage information.

This clang test unfortunately depends on the actions of the optimizer,
which some of the buildbots hit.
This patch makes it so it cannot ignore the return value of 'f', so it
won't do away with the implementation.
This patch provides an implementation for `spv.func` conversion. The pattern
is populated in a separate method added to the pass. At the moment, the type
signature conversion only includes the supported types. The conversion pattern
also matches SPIR-V function control attributes to LLVM function attributes.
Those are modelled as `passthrough` attributes in LLVM dialect. The following
mapping are used:
- None: no attributes passed
- Inline: `alwaysinline` seems to be the right equivalent (`inlinehint` is
semantically weaker in my opinion)
- DontInline: `noinline`
- Pure and Const: I think those can be modelled as `readonly` and `readnone`
attributes respectively.
Also, 2 patterns added for return ops conversion (`spv.Return` for void return
and `spv.ReturnValue` for a single value return).

The VLLDM and VLSTM instructions are incompletely specified. They
(potentially) write (or read, respectively) registers Q0-Q7, VPR, and
FPSCR, but the compiler is unaware of it.
In the new test case `cmse-vlldm-no-reorder.ll` case the compiler
missed an anti-dependency and reordered a `VLLDM` ahead of the
instruction, which stashed the return value from the non-secure call,
effectively clobbering said value.
This test case does not fail with upstream LLVM, because of scheduling
differences and I couldn't find a test case for the VLSTM either.

Summary:
As discussed previously when landing patch for OpenMP in Flang, the idea is
to share common part of the OpenMP declaration between the different Frontend.
While doing this it was thought that moving to tablegen instead of Macros will also
give a cleaner and more powerful way of generating these declaration.
This first part of a future series of patches is setting up the base .td file for
DirectiveLanguage as well as the OpenMP version of it. The base file is meant to
be used by other directive language such as OpenACC.
In this first patch, the Directive and Clause enums are generated with tablegen
instead of the macros on OMPConstants.h. The next pacth will extend this
to other enum and move the Flang frontend to use it.

Currently when the .eh_frame section is truncated so that
CFI instructions can't be read, it is possible to enter
an infinite loop.
It happens because `CFIProgram::parse` does not handle errors properly.
This patch fixes the issue.

Summary:
Adds a fuzz test for string comparison.
This takes in two strings with associated lengths.
Verifies each string contains at least one character, and that the last character is the null terminator.
Then, finds the first instance where one of the following does not hold:
1. i < min(size1, size2)
2. s1[i] == s2[i]
3. s1[i] != '\0'
The result of strcmp is then compared to the value of the difference between s1[i] and s2[i]. For thoroughness, the operands are reversed and also checked.

Currently, using the nullPointerConstant AST matcher can lead to
assertions in situations where a node to be matched does not have a
valid type associated with it, such as a ParenListExpr. This patch
addresses that by saying such nodes cannot be a null pointer constant.
This addresses PR46353.
This patch contains:
- Support in LLVM CodeGen for bfloat16 types for ld2/3/4 and st2/3/4.
- New bfloat16 ACLE builtins for svld(2|3|4)[_vnum] and svst(2|3|4)[_vnum]
