Vectors in D are exposed by the use of the `__vector(T[N])' type, and
whilst most unary and binary operations work as you'd expect, there are
some operations that are not possible without doing the operation
unrolled, or calling some target-specific built-in, or with inline asm.
This introduces a new `gcc.simd' module that introduces the following.
- Prefetching has been exposed by a convenient `prefetch' function in
the library.
- Loading and storing from an unaligned address have been exposed by
`loadUnaligned' and `storeUnaligned' intrinsics.
- Vector permutations have been exposed by `shuffle`, and
`shufflevector' intrinsics.
- Converting between two vectors with a different element type has been
exposed by a `convertvector' intrinsic.
- The ternary operator has been exposed with a `blendvector' intrinsic.
- Comparison operators have been exposed by `equalMask',
`notEqualMask', `greaterMask', and `greaterEqualMask' intrinsics.
- Logic operators have been exposed by convenient `notMask',
`andAndMask', and `orOrMask' functions in the library.
To be compatible with the LLVM D compiler's own SIMD intrinsic module,
there is also the addition of an `extractelement' and `insertelement'
convenience functions, and an alternative interface for calling the
`shufflevector' function.
The addition of these intrinsics lowers the boundary for users working
in SIMD to get the desired codegen they want out of the compiler.
Most of what is present here - apart from tests - is the adding of
machinery in the intrinsics suite of functions to do validation on
templated intrinsics. Whilst these are still matched from the library
by their generic (untyped) signature, there is a still an assumption
that what has been instantiated and handed down to the code generator is
valid, because why would these definitions be found outside of the
in-tree D runtime library? The majority of intrinsics are not
templates, so the test on the mangled signature string still guarantees
all types are as we expect them to be. However there are still a small
handful of other templated intrinsics (core.bitop.{rol,ror},
core.math.toPrec, std.math.traits.isNaN, ...) that are currently
unchecked, so would benefit from being included into this built-in
checking function at some point in the future.

The `@register` attribute specifies that a local or `__gshared` variable
is to be given a register storage-class in the C sense of the term, and
will be placed into a register named `registerName`.
The variable needs to boiled down to a data type that fits the target
register. It also cannot have either thread-local or `extern` storage.
It is an error to take the address of a register variable.

This patch adds support to gcc's diagnostic subsystem for emitting
diagnostics in SARIF, aka the Static Analysis Results Interchange Format:
https://sarifweb.azurewebsites.net/
by extending -fdiagnostics-format= to add two new options:
-fdiagnostics-format=sarif-stderr
and:
-fdiagnostics-format=sarif-file
The patch targets SARIF v2.1.0
This is a JSON-based format suited for capturing the results of static
analysis tools (like GCC's -fanalyzer), but it can also be used for plain
GCC warnings and errors.
SARIF supports per-event metadata in diagnostic paths such as
["acquire", "resource"] and ["release", "lock"] (specifically, the
threadFlowLocation "kinds" property: SARIF v2.1.0 section 3.38.8), so
the patch extends GCC"s diagnostic_event subclass with a "struct meaning"
with similar purpose. The patch implements this for -fanalyzer so that
the various state-machine-based warnings set these in the SARIF output.
The heart of the implementation is in the new file
diagnostic-format-sarif.cc. Much of the rest of the patch is interface
classes, isolating the diagnostic subsystem (which has no knowledge of
e.g. tree or langhook) from the "client" code in the compiler proper
cc1 etc).
The patch adds a langhook for specifying the SARIF v2.1.0
"artifact.sourceLanguage" property, based on the list in
SARIF v2.1.0 Appendix J.
The patch adds automated DejaGnu tests to our testsuite via new
scan-sarif-file and scan-sarif-file-not directives (although these
merely use regexps, rather than attempting to use a proper JSON parser).
I've tested the patch by hand using the validator at:
https://sarifweb.azurewebsites.net/Validation
and the react-based viewer at:
https://microsoft.github.io/sarif-web-component/
which successfully shows most of the information (although not paths,
and not CWE IDs), and I've fixed all validation errors I've seen (though
bugs no doubt remain).
I've also tested the generated SARIF using the VS Code extension linked
to from the SARIF website; I'm a novice with VS Code, but it seems to be
able to handle my generated SARIF files (e.g. showing the data in the
SARIF tab, and showing squiggly underlines under issues, and when I
click on them, it visualizes the events in the path inline within the
source window).
Has anyone written an Emacs mode for SARIF files? (pretty please)

Fixes a segfault seen on Darwin when a GC scan is ran after a thread has
been destroyed. As the global emutlsArrays hash still has a reference

However, it's now well possible to enable it both for Solaris/x86 with
as and Solaris/SPARC (both as and gas) since the original problems (x86
as linelength limit, among others) are long gone.
The following patch does just that.
Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11 (both as and
gas) with gdc 9.3.0 (x86) resp. 9.4.0 (sparc, configured with
--enable-libphobos) as bootstrap compilers.

PR d/103528
* configure.ac <x86_64-*-solaris2.* | i?86-*-solaris2.*>: Remove
gas requirement.
* configure: Regenerate.
* configure.tgt (sparc*-*-solaris2.11*): Mark supported.
D front-end changes:
- Import dmd v2.099.0-beta.1.
- It's now an error to use `alias this' for partial assignment.
- The `delete' keyword has been removed from the language.
- Using `this' and `super' as types has been removed from the
language, the parser no longer specially handles this wrong code
with an informative error.
D Runtime changes:
- Import druntime v2.099.0-beta.1.
Phobos changes:
- Import phobos v2.099.0-beta.1.

- The std.experimental.checkedint module has been renamed to
std.checkedint.
