Functions in DWARFYML::FixupVisitor are declared as
virtual functions in its base class DWARFYAML::Visitor.
We should use the mordern "override" keyword instead
of "virtual" for virtual functions in subclasses for
better safety.
Besides, the visibility is changed from private to
protected to make it consistent with
DWARFYAML::FixupVisitor class and DWARFYAML::Visitor
class.

When adding support for scalable vector masked loads and stores we
accidently opened up likewise for fixed length vectors. This patch
restricts support to scalable vectors only, thus ensuring fixed
length vectors are treated the same regardless of SVE support.
Differential Revision: https://reviews.llvm.org/D83341
Fixed length vector code generation for SVE does not yet custom
lower BUILD_VECTOR and instead relies on expansion. At the same
time custom lowering for VECTOR_SHUFFLE is also not available so
this patch updates isShuffleMaskLegal to reject vector types that
require SVE.
Related to this it also prevents the merging of stores after
legalisation because this only works when BUILD_VECTOR is either
legal or can be elminated. When this is not the case the code
generator enters an infinite legalisation loop.

Summary:
New line duplication logic introduced in https://reviews.llvm.org/D63482
has two issues: (1) there is no logic that removes duplicate newlines
when clang-apply-replacment reads YAML and (2) in general such logic
should be applied to all strings and should happen on string
serialization level instead in YAML parser.
This diff changes multiline strings quotation from single quote `'` to
double `"`. It solves problems with internal newlines because now they are
escaped. Also double quotation solves the problem with leading whitespace after
newline. In case of single quotation YAML parsers should remove leading
whitespace according to specification. In case of double quotation these
leading are internal space and they are preserved. There is no way to
instruct YAML parsers to preserve leading whitespaces after newline so
double quotation is the only viable option that solves all problems at
once.

Summary:
Added canonicalization and folding was:
- Folding when either input is an attribute indicating a scalar input
which can always be broadcasted.
- Canonicalization where it can be determined that either input shape is
a scalar.
- Canonicalization where the partially specified input shapes can be
proven to be broadcastable always.

locations (registers/memory) of source-level variables alongside the

counter range in which it is valid.

OriginalOp of a predicate always refers to the original IR
value that was renamed. So for nested predicates of the same value, it
will always refer to the original IR value.
For the use in SCCP however, we need to find the renamed value that is
currently used in the condition associated with the predicate. This
patch adds a new RenamedOp field to do exactly that.
NewGVN currently relies on the existing behavior to merge instruction
metadata. A test case to check for exactly that has been added in
195fa4bfae.

Summary:
When legalizing a biscast operation from an fp16 operand to an i16 on a
target that requires both input and output types to be promoted to
32-bits, an assertion can fail when building the new node due to a
mismatch between the the operation's result size and the type specified to
the node.
This patches fix the issue by making sure the bit width of the types
match for the FP_TO_FP16 node, covering the difference with an extra
ANYEXTEND operation.

Replace mutiple `if else` clauses with a `switch` clause and remove redundant checks. Before this patch, we need to add a statement like `if(!isa<MCxxxFragment>(Frag)) ` here each time we add a new kind of `MCEncodedFragment` even if it has no fixups. After this patch, we don't need to do that.

Summary:
A few things were broken:
- use of Document::parseBlockNode() is incorrect and prevents moving to the
next doc in error cases. Use getRoot() instead.
- bailing out in the middle of iterating over a list/dict isn't allowed,
unless you are going to throw away the parser: the next skip() asserts.
Always consume all items.
- There were two concepts of fatal errors: error-diagnostics and drop-fragment.
(The latter is the "return false" case in the parser). They didn't coincide.
Now, parser errors and explicitly emitted error diagnostics are fatal.

This seems to be leftover copied from an older implementation
of getHostCPUName where we needed this to check the name of
CPU vendor. We don't check the CPU vendor at all in
getHostCPUFeatures so this union and the variable are unneeded.
To avoid linkage errors we have to ensure the linkage allows multiple
definitions of these compiler inserted functions. Since they are on the
cold path of complex computations, we want to avoid `inline`. Instead,
we opt for `weak` and `noinline` for now.
In this change, `parseDWARFYAML()` is refactored to be able to parse
YAML decription into different data structures. We don't have to craft
the whole DWARF structure for a small test in the future.

* This allows these flags to be passed on the command line with normal CMake bool-interpreted values like ON/OFF instead of requiring 0/1.
* As-is, if passing ON/OFF, these will cause a parse error in lit.site.cfg.py because Python tries to interpret the string literally.

9cac4e6d1403554b06ec2fc9d834087b1234b695/D32628 intended to eliminate
this, and move all isel pseudo expansion to FinalizeISel. This was a
bad rebase or something, and failed to actually delete this call.
GlobalISel also has a redundant call of finalizeLowering. However, it
requires more work to remove it since it currently triggers a lot of
verifier errors in tests.
This simply follows the scheme we have for other wrappers. It resolves
the current link problem, e.g., `__muldc3 not found`, when std::complex
operations are used on a device.
This will not allow complex make math function calls to work properly,
e.g., sin, but that is more complex (pan intended) anyway.
