yaml2obj does not record the source filename in the output,
which may make FileCheck tests brittle sometimes.
Summary: Functional.h contains many different methods that have a direct, and more efficient, equivalent in LLVM. This revision replaces all usages with the LLVM equivalent, and removes the header. This is part of larger cleanup, pr45513, merging MLIR support facilities into LLVM.

The libc++ test suite currently defines several features that are not
used anywhere in the tests, or that are redundant with other features.
For the purpose of simplifying config.py and to ease the bring up of a
new configuration, this commit removes some of these features:
- rename dylib-has-no-filesystem to c++filesystem-disabled, which exists
- rename apple-darwin to just darwin, which is already set
- remove useless setting of libstdc++, which is already set correctly
- remove libcpp-abi-unstable, which is not used anywhere
- remove the glibc-XXX features, which are not used anywhere
I broke bots last week and tried a few things to fix them.
These were attempts that didn't help, so back them back out.
This reverts commit c7aff9a109.
This reverts commit 8838d6d356.
This reverts commit e875ba1509.
This is equivalent in terms of LLVM IR semantics, but we want to
transition away from using MaybeAlign to represent the alignment of
these instructions.

Summary:
Previously `AtosSymbolizer` would set the PID to examine in the
constructor which is called early on during sanitizer init. This can
lead to incorrect behaviour in the case of a fork() because if the
symbolizer is launched in the child it will be told examine the parent
process rather than the child.
To fix this the PID is determined just before the symbolizer is
launched.
A test case is included that triggers the buggy behaviour that existed
prior to this patch. The test observes the PID that `atos` was called
on. It also examines the symbolized stacktrace. Prior to this patch
`atos` failed to symbolize the stacktrace giving output that looked
like...
```
#0 0x100fc3bb5 in __sanitizer_print_stack_trace asan_stack.cpp:86
#1 0x10490dd36 in PrintStack+0x56 (/path/to/print-stack-trace-in-code-loaded-after-fork.cpp.tmp_shared_lib.dylib:x86_64+0xd36)
#2 0x100f6f986 in main+0x4a6 (/path/to/print-stack-trace-in-code-loaded-after-fork.cpp.tmp_loader:x86_64+0x100001986)
#3 0x7fff714f1cc8 in start+0x0 (/usr/lib/system/libdyld.dylib:x86_64+0x1acc8)
```
After this patch stackframes `#1` and `#2` are fully symbolized.
This patch is also a pre-requisite refactor for rdar://problem/58789439.

Summary:
In preparation for writing a test for a bug fix we need to be able to
see the command used to launch the symbolizer process. This feature
will likely be useful for debugging how the Sanitizers use the
symbolizer in general.
This patch causes the command line used to launch the process to be
shown at verbosity level 3 and higher.
A small test case is included.

The alignment of ARM64 range extension thunks was fixed in
7c81649219, but ARM range extension thunks, and import
and delay import thunks also need aligning (like all code on ARM
platforms).
I'm adding a test for alignment of ARM64 import thunks - not
specifically adding tests for misalignment of all of them though.

This change is NFC since the facility to tile and generate
loop.parallel loops already exists in Linalg.
Differential Revision: https://reviews.llvm.org/D77965
The invertPermutation method does not return a nullptr anymore, but
rather returns an empty map for the scalar case. Update the check in
LinalgToLoops to reflect this.
Also add test case for generating scalar code.
The outer parallel loops of a linalg operation is lowered to
loop.parallel, with the other loops lowered to loop.for. This gets the
lowering to loop.parallel on par with the loop.for lowering. In future
the reduction loop could also be lowered to loop.parallel.
Also add a utility function that returns the loops that are
created.

Add a quote character to the sed command to cause it to be quoted.
Hopefully, which will help both gnuwin and MSys versions of sed tokenize
the command line the same way.
Summary:
Caveats:
- only works when the header is changed in the editor and the editor provides
the notification
- we revalidate preambles for all open files (stat all their headers) rather
than taking advantage of the fact that we know which file changed.
This is much simpler!

This patch extracts the RTTI part of llvm::ErrorInfo into its own class
(RTTIExtends) so that it can be used in other non-error hierarchies, and makes
it compatible with the existing LLVM RTTI function templates (isa, cast,
dyn_cast, dyn_cast_or_null) by adding the classof method.

In the case of more than one SDep between two successor SUnits in the Nodeset, the current implementation sums the latencies of the dependencies, which could create a larger RecMII than necessary.
for example, in case there is both a data dependency and an output dependency (with latency > 0) between successor nodes:
SU(1) inst1:
successors:
SU(2): out latency = 1
SU(2): data latency = 1
SU(2) inst2:
successors:
SU(3): out latency = 1
SU(3): data latency = 1
SU(3) inst3:
successors:
SU(1): out latency = 1
SU(1): data latency = 1
the NodeSet latency returned would be 6, whereas it could be 3 if we take the max for each successor SUnit.
In general this can be extended to finding the shortest path in the recurrence..
thoughts?
Unfortunately I had a hard time creating a test for this in Hexagon/PowerPC, so help would be appreciated.

I didn't realize HIP was a distinct offloading kind, so the subtarget
was looking for -march, which isn't correct for HIP. We also have the
possibility of different denormal defaults in the case of multiple
offload targets, so we need to thread the JobAction through the target
hook.
in the same section.
This allows specifying BasicBlock clusters like the following example:
!foo
!!0 1 2
!!4
This places basic blocks 0, 1, and 2 in one section in this order, and
places basic block #4 in a single section of its own.
NFC clean up for simplify-affine-structures test cases. Rename sets
better; avoid suffix numbers; move outlined definitions close to use.
This is in preparation for other functionality updates.

Without this, the LLVM utilities (FileCheck) aren't built when running
`ninja check-flang` and it fails with:

Also the modules aren't built without depending on `module_files`, which
makes multiple tests failing.

This commit added stride support in runtime array types. It also
adjusted the assembly form for the stride from `[N]` to `stride=N`.
This makes the IR more readable, especially for the cases where

Share logic to strip debugify metadata between the IR and MIR level

Rename extract-instrmap-aarch64.test to extract-instrmap.test because
the path component `AArch64` conveys the target name clearly.
Additionally, adopt a convention we start to use in LLVM binary
utilities: prepend `#` to CHECK/RUN lines and `##` to comment lines even
if the file contains no code. The notation makes CHECK/RUN/comments
stand out.
