This test uses a precompiled object and duplicates
the functionality of a modern elf-no-symtab.yaml test that
uses yaml2obj for producing inputs.

This is a follow-up for D75608.
The `Offset` property is unused and can be removed to reduce tests.

This patch does nothing with `reloc-types-elf-i386.test` which has a different
structure and kind of tests the `Offset`. I think we might want to split it probably.

The logic in select_cc is messy and hard to follow. This is a NFC patch to simplify the logic.

According to LangRef:
If len is not a positive integer multiple of element_size, then the behaviour of the intrinsic is undefined.

Add InstCombine rule to transform intrinsic to undef operation.

This is a follow-up for D76116.

- Detect "c_1 * expr + c_2 * expr" as (c_1 + c_2) * expr
- subsumes things like 'expr - expr' and "expr * -1 + expr" as 0.
- change AffineConstantExpr ctor to allow default null init

Summary: This adds bitfields that map to the dialect attribute verifier hooks. This also moves over the Test dialect to have its declaration generated.

Currently, when building with the Unix support library and `isatty` does
not exist for the target platform (i.e. `HAVE_ISATTY` is false),
compilation of the file `raw_ostream.cpp` will fail due to direct use of
`isatty` in the function `raw_fd_ostream::preferred_buffer_size()`.

Use is_displayed() to fix the problem.

This fails an assert because the type is marked in the calling
convention td file as needing promotion, but the code doesn't know
how to do it.

It also much more complicated because we try to pass these in
xmm/ymm/zmm registers. As of a few weeks ago we do this promotion
from getRegisterTypeForCallingConv before the td file generated
code gets involved.

which is the more appropriate API for its use-case.

This test fails on ppc which was unintended.

Revision: D73674.

Summary: PatternState was a mechanism to pass state between the match and rewrite calls of a RewritePattern. With the rise of matchAndRewrite, this class is unused and unnecessary. This revision removes PatternState and simplifies PatternMatchResult to just be a LogicalResult. A future revision will replace all usages of PatternMatchResult/matchSuccess/matchFailure with LogicalResult equivalents.

Fixes -Werror builds.

Note that I'm not asserting this code is correct; I'm simply adding coverage for what's there already.  I'm reasonable sure the logic works for existing relaxable instructions, but I wouldn't be suprised if there were incorrect cases for other instructions.  (i.e. is it legal to add prefixes to all instructions?)

- libclang_rt.profile should be added when -fcs-profile-generate is on thecommand line.
- OPT_fno_profile_instr_generate was used as a negative for OPT_fprofile_generate. Fix it to use OPT_fno_profile_generate.

[Concepts] Fix incorrect control flow when TryAnnotateTypeConstraint annotates an invalid template-id

TryAnnotateTypeConstraint could annotate a template-id which doesn't end up being a type-constraint,
in which case control flow would incorrectly flow into ParseImplicitInt.

Reenter the loop in this case.
Enable relevant tests for C++20. This required disabling typo-correction during TryAnnotateTypeConstraint
and changing a test case which is broken due to a separate bug (will be reported and handled separately).

Summary:
Run StackSafetyAnalysis at the end of the IR pipeline and annotate
proven safe allocas with !stack-safe metadata. Do not instrument such
allocas in the AArch64StackTagging pass.

This is the second patch in a series of patches to enable basic block
sections support.

This patch adds support for:

* Creating direct jumps at the end of basic blocks that have fall
through instructions.
* New pass, bbsections-prepare, that analyzes placement of basic blocks
in sections.
* Actual placing of a basic block in a unique section with special
handling of exception handling blocks.
* Supports placing a subset of basic blocks in a unique section.
* Support for MIR serialization and deserialization with basic block
sections.

Summary:
This regional op in the QuantOps dialect will be used to wrap
high-precision ops into atomic units for quantization. All the values
used by the internal ops are captured explicitly by the op inputs. The
quantization parameters of the inputs and outputs are stored in the
attributes.
