Significant missing hashing - as per the comment this was only meant to
skip member functions (unspecified, but I think it's legible as member
function declarations, not definitions) but was skipping all named
subprograms (so only hashed child DIEs for member function definitions -
because they didn't have a direct name, but only a name given indirectly
in the DW_AT_specification-referenced DIE)

This avoids a potentially expensive scan if we already know it doesn't
matter.

Separated from https://reviews.llvm.org/D68006 review.

Summary:
This patch introduces an alternative calling convention for
MemRef function arguments in LLVM dialect. It converts MemRef
function arguments to LLVM bare pointers to the MemRef element
type instead of creating a MemRef descriptor. Bare pointers are
then promoted to a MemRef descriptors at the beginning of the
function. This calling convention is only enabled with a flag.

Specializations of the Platform class print the kernel after calling the
super method. By printing the kernel at the end in the super class, we
guarantee the order is the same on different platforms.

This reverts commit deae8ee6 as it
broke the build on several bots.

Summary:
Implements the jump pseudo-instruction, which is used in e.g. the Linux kernel.

This change has two components. The moves the generated file
for a namespace to the directory named after the namespace in
a file named 'index.<format>'. This greatly improves the browsing
experience since the index page is shown by default for a directory.

The second improves the markdown output by adding the links to the
referenced pages for children objects and the link back to the source
code.

Temporarily revert to fix the tests that only fail on the bots because
of the newly enforced substr order.

instead of the "enabled by default" color.

It may be technically correct to list unimplemented diagnostics as
"enabled by default" but it's quite misleading.

This patch changes the behavior of the substrs argument to self.expect.
Currently, the elements of substrs are unordered and as long as the
string appears in the output, the assertion passes.

We can be more precise by requiring that the substrings be ordered in
the way they appear. My hope is that this will make it harder to
accidentally pass a check because a string appears out of order.

Differential revision: https://reviews.llvm.org/D73766

Currently the substrs parameter takes a list of strings that need to be
found but the ordering isn't checked. D73766 might change that so this
changes a several tests so that the order of the strings in the substrs
list is in the order in which they appear in the output.

The functions are used, but empty when NDEBUG is set.

This revision does the following post-commit cleanups:
1. don't use -1 magic constants,
2. drop commented out old test that does not belong here,
3. reformat and add a proper clang-format off on a CHECK directive.

This test didn't need any local variables or parameters, and didn't need
to be checking the DWO ID or more detailed forms.

It was using -v to print the macro sections, but now that macro sections
are emitted when requested (-debug-macro) that's not needed either.

types are needed to compute the return type of a defaulted operator<=>.

This raises the question of what to do if return type deduction fails.
The standard doesn't say, and implementations vary, so for now reject
that case eagerly to keep our options open.

Summary:
This revision provides 2 versions of matmul with tensors to account for the differences in buffer vs value semantics:
1. `C(i, j) = sum_{r_k} A(i, r_k) * B(r_k, j)`
2. `D(i, j) = C(i, j) + sum_{r_k} A(i, r_k) * B(r_k, j)`

If dumping an Split DWARF file that hasn't been split into separate
files (such as from llc - that includes the plain and .dwo sections in
the same file) allow both macinfo and macinfo.dwo sections to be dumped.

Currently the substrs parameter takes a list of strings that need to be
found but the ordering isn't checked. D73766 might change that so this
changes a several tests so that the order of the strings in the substrs
list is in the order in which they appear in the output.

Summary:
This change represents the move of ClangASTImporter, ClangASTMetadata,
ClangExternalASTSourceCallbacks, ClangUtil, CxxModuleHandler, and
TypeSystemClang from lldbSource to lldbPluginExpressionParserClang.h

This explicitly removes knowledge of clang internals from lldbSymbol,
moving towards a more generic core implementation of lldb.

Summary:
This revision beefs up the debug logging within dialect conversion. Given the nature of multi-level legalization, and legalization in general, it is one of the harder pieces of infrastructure to debug. This revision adds nice formatting to make the output log easier to parse:

```
Legalizing operation : 'std.constant'(0x608000002420) {
  * Fold {
  } -> FAILURE : unable to fold

  * Pattern : 'std.constant -> ()' {
  } -> FAILURE : pattern failed to match

  * Pattern : 'std.constant -> ()' {
  } -> FAILURE : pattern failed to match

  * Pattern : 'std.constant -> (spv.constant)' {
    ** Insert  : 'spv.constant'(0x608000002c20)
    ** Replace : 'std.constant'(0x608000002420)

Summary:
Rationale:
When lowering to LLVM for different rank insert (n vs k), the offset
arrays needs to drop one dimension (becomes n-1), but the strides
array needs to be preserved (remains k). With regression test.
Note that this example was actually in the documentation, so
extra important to do it right :-)

because at this point there are two instructions defining Res: the
original G_SMULO/G_UMULO and the new G_MUL that we built. The fix is
to modify the original mul in place, so that there is only ever one
definition of Res.

When you encounter a G_TRUNC, you are moving from a larger type to a smaller
type.

Asking for the i-th bit on a larger value is the same as asking for the i-th
bit on a smaller value.

So, we should always be able to walk through G_TRUNC when computing the bit
for a TB(N)Z.

Use the StringRef constructor instead of toStringRef so we don't end up
with the wrong overload (llvm::toStringRef(bool)).

Fixes PR44736

If we don't demand any elements of the inserted subvector then just skip it.

This is a leftover of a temporary state where loop operations were in Standard
dialect.

Summary:
After the `subview` operation was migrated from Linalg to Standard, it changed
semantics and does not guarantee the absence of out-of-bounds accesses through
the created view anymore. Compute the size of the subview to make sure it
always fits within the view (subviews in last iterations of the loops may be
smaller than those in other iterations).
