included for gnu readelf compatibility and ignored. This change makes -W
an alias of --wide to be consistent with other option aliases.

Polly is trying to move towards using isl::ast_expr / isl-noexceptions.h

checkIslAstExprInt manually frees Expr, so it has been removed to be

Fix a bug introduced while refactoring ABIAArch64::AugmentRegisterInfo()

Instead, abort immediately if at least one subregister is found

I was not able to reproduce the problem, but I added an extra check
for a NULL QualType just in case.

Original comit message:

The patch adds missing diagnostics for cases like:

  float F3 = ((__float128)F1 * (__float128)F2) / 2.0f;

Sema::checkDeviceDecl (renamed to checkTypeSupport) is changed to work
with a type without the corresponding ValueDecl. It is also refactored
so that host diagnostics for unsupported types can be added here as
well.

Similar to D111236, this improves the lowering of vector fptosi.sat and

That script is what we (need to) use to build libc++ for the system
configuration, so that's what we should test against. At some point
we may be able to fold all of that logic into the CMake build, and
when that happens the CI can go back to running CMake directly.

As a fly-by fix, stop mentioning x86_64 in the names of the Apple
jobs since they are not truly tied to any architecture.

[git-clang-format][PR46815] Add diffstat functionality

Adding a --diffstat parameter to git-clang-format that essentially uses git diff --stat, i.e. lists the files needing
formatting. This is useful for CI integration or manual usage where one wants to list the files not properly formatted.

I use it for the Suricata project's github action (CI) integration that verifies proper formatting of a pull request
according to project guidelines where it's very helpful to say which files are not properly formatted. I find the list
of files much more useful than e.g. showing the diff in this case using git-clang-format --diff.

An alternative would be to take an additional parameter to diff, e.g. git-clang-format --diff --stat

The goal is not to provide the whole git diff --stat=... parameter functionality, just plain git diff --stat.

This patch aim to find a trivial, but not that sophisticated way of emitting the error without the additional impact of adding libFrontEnd to clang-format.

This adds a new parser and printer for text which may be a keyword or a
string. When printing, it will attempt to print the text as a keyword,
but if it has any special or non-printable characters, it will be
printed as an escaped string.  When parsing, it will parse either a
valid keyword or a potentially escaped string. The printer allows for an
empty string, in which case it prints `""`.

This new function is used for printing the name in NamedAttributes, and
for printing the symbol name after the `@`. In CIRCT we are using this
to print module port names, which are conceptually similar to named
function arguments.

When DynamicLoaderMacOS::SetNotificationBreakpoint sets the breakpoint
for new binaries being loaded/unloaded, it limits the scope of that
breakpoint to just dyld, so we don't re-evaluate the breakpoint for
every new binary loaded.  I wrote this to get the module's ObjectFile
FileSpec in an earlier change, but this is not correct.  If lldb
is debugging a remote system, and it had to read dyld out of memory
from the remote system, it will have no FileSpec on the lldb debugger
host.  We need to grab the Module's FileSpec, which in this case is
actually falling back to the PlatformFileSpec, the binary path on the
target system.
