[MCAsmParser] .macro/.rept/.irp/.irpc: remove excess \n after expansion
```
.irp foo,1
nop
.endr
nop
```
expands to an excess EOL between two nop lines. Other loop directives
and .macro have the same issue.
`Lex()` at "Jump to the macro instantiation and prime the lexer"
requires that there is one single \n token in CurTok. Therefore, we
cannot consume the trailing \n when parsing the macro(-like) body.
(commit c6e787f771d1f9d6a846b2d9b8db6adcd87e8dba (reverted by
1e5f29af81a5f6fda308074f6345b9fba4faa71c))
Instead, skip the potential \n after jumpToLoc at handleMacroExit.
Fix: remove wrongly pushed etime-function.mlir at toplevel (#92634)
The purpose of this PR is to remove the 'etime-function.mlir' file that
I mistakenly committed in
https://github.com/llvm/llvm-project/pull/92571. This file is not
necessary in source code control, and its presence may cause confusion
or misunderstanding.
[Github] Revert accidental changes to dependabot config
f3524e9aebbfabed0c60d0087b39ce14d8f778da accidentally touched the
dependabot config. This patch reverts that change.
[clang] Don't assume location of compiler-rt for OpenBSD (#92183)
If the `/usr/lib/...` path where compiler-rt is conventionally installed
on OpenBSD does not exist, fall back to the regular logic to find it.
This is a minimal change to allow OpenBSD cross compilation from a
toolchain that doesn't adopt all of OpenBSD's monorepo's conventions.

[Bounds-Safety] Temporarily relax a `counted_by` attribute restriction on flexible array members
In 0ec3b972e58bcbcdc1bebe1696ea37f2931287c3 an additional restriction
was added when applying the `counted_by` attribute to flexible array
members in structs. The restriction prevented the element type being
a struct that itself had a flexible array member. E.g.:
```
struct has_unannotated_VLA {
int count;
char buffer[];
};
struct buffer_of_structs_with_unnannotated_vla {
int count;
struct has_unannotated_VLA Arr[] __counted_by(count);
};
```

[mlir][polynomial] split attributes into its own tablegen (#92613)
Out of tree we have other dialects that use the ring attribute, but we
get compilation errors when generating ops while pulling in all the
Polynomial tablegen ops (there's no `-dialect` flag in `mlir-tblgen` for
op generation like there is for attributes and types).
This PR simply moves the attributes into its own file, so it can be
included separately, and this also requires moving the dialect
declaration into its own file.
[flang] Relax checking of dummy procedures under BIND(C) (#92474)
As was done recently to allow derived types that are not explicitly
BIND(C), but meet the requirements of BIND(C), to be acceptable for use
in contexts nominally requiring BIND(C), this patch allows procedures
that are not explicitly BIND(C) to be used in contexts that nominally
require BIND(C) so long as (1) they meet the requirements of BIND(C),
and (2) don't use dummy arguments whose implementations may vary under
BIND(C), such as VALUE.
[flang][runtime] Decouple scalar output APIs from descriptors (#92444)
For testing purposes the implementations of the output APIs like
OutputInteger32 have been simply constructing descriptors and executing
the operation through the general DescriptorIO template. This patch
decouples those APIs from that mechanism so that programs using simple
"PRINT *" statements for output can link to a smaller portion of the I/O
runtime support library. (This is the only form of I/O accepted in GPU
device code by previous CUDA Fortran and Fortran OpenACC compilers.)
[NVPTX] fixup support for over-aligned parameters (#92457)
This extends the NVPTX support for over-aligned parameters and return
values in a few related ways:
- Support for `alignstack` attribute, as an alternative to legacy nvvm
`!"align"` metadata entries. While we still maintain the legacy support,
long term it might be nice to auto-upgrade to `alignstack`.
- Check the alignment info when emitting the parameter list to prevent a
mismatch between alignment of caller and callee, which would previously
cause a fatal error for `ptxas`.
- Check the alignment info when emitting loads for parameters,
potentially enabling better vectorization.
[flang][cuda] Implicitly load cudadevice module in device/global subprogram (#92038)
This is a re-worked version of #91668. It adds the `cudadevice` module
and set the `device` attributes on its functions/subroutines so there is
no need for special case in semantic check.
`cudadevice` module is implicitly USE'd in `global`/`device` subprogram.
Fix flaky test: signal_in_mutex_lock.cpp (#92587)
Fix flaky test: the spawned thread keeps spinning
on `sampler_mutex` which may be released before
the thread is terminated based on termination
ordering.
My understanding of C++ semantics are that the
program here is invalid: the destructors of global
variables are invoked at the time of program
termination, and it is the responsibility of the
program to ensure that invoking those destructors
is safe.

[GlobalOpt] Don't replace aliasee with alias that has weak linkage (#91483)
Fixes #91312.
Don't perform the transform if the alias may be replaced at link time.

[Arm64EC] Correctly handle sret in entry thunks. (#92326)
I accidentally left out the code to transfer sret attributes to entry
thunks, so values weren't being passed in the right registers, and the
sret pointer wasn't returned in the correct register.
Fixes #90229
[Arm64EC] Improve alignment mangling in arm64ec thunks. (#90115)
In some cases, MSVC's mangling for arm64ec thunks includes the alignment
of a struct. I added some code to try to match... but it never really
worked right. The issues:
- Alignment is only mangled if it's 16 or more (I guess the default is
supposed to be 8).
- Alignment isn't mangled on return values (since the memory is
allocated by the caller).
The current patch leaves hooks to make alignment mangling work... but
doesn't actually ever mangle alignment: clang never actually encodes a
relevant alignment into the IR. Once we get clang to emit the real
size/alignment of structs, we can start emitting it.
