[Clang] remove redundant uses of dyn_cast (NFC) (#189106)
This removes dyn_cast invocations where the argument is already of the
target type (including through subtyping). This was created by adding a
static assert in dyn_cast and letting an LLM iterate until the code base
compiled. I then went through each example and cleaned it up. This does
not commit the static assert in dyn_cast, because it would prevent a lot
of uses in templated code. To prevent backsliding we should instead add
an LLVM aware version of
https://clang.llvm.org/extra/clang-tidy/checks/readability/redundant-casting.html
(or expand the existing one).
[clang][RISC-V] fixed fp calling convention for fpcc eligible structs for risc-v (#110690)
The code generated for calls with FPCC eligible structs as arguments
doesn't consider the bitfield, which results in a store crossing the
boundary of the memory allocated using alloca, e.g.
For the code:
```
struct __attribute__((packed, aligned(1))) S {
const float f0;
unsigned f1 : 1;
};
unsigned func(struct S arg)
{
return arg.f1;
}
```
The generated IR is:
```
define dso_local signext i32 @func(

[Fuchsia] Set LIBCXX_ABI_UNSTABLE instead of LIBCXX_ABI_VERSION (#189123)
Use the generic switch rather than encoding the version number it
currently corresponds to.
[libc] Remove more header template files (#189066)
Get rid of several .h.def files which were used to ensure that the
macro definitions from llvm-libc-macro would be included in the public
header. Replace this logic with YAML instead - add entries to the
"macros" list that point to the correct "macro_header" to ensure it
would be included.
For C standard library headers, list several standard-define macros
to document their availability. For POSIX/Linux headers, only reference
a handful of macro, since more planning is needed to decide how to
represent platform-specific macro in YAML.
[libclc] Fix llvm-spirv dependency when llvm-spirv is built in-tree (#188896)
When SPIRV-LLVM-Translator is built in-tree (i.e., placed in
llvm/projects folder), llvm-spirv target exists.
Drop legacy llvm-spirv_target dependency (was for non-runtime build) and
add llvm-spirv to runtimes dependencies.
[SPIRV][Matrix] Legalize store of matrix to array of vector memory layout (#188139)
fixes #188131
This change address stylistic changes @bogners requested in
https://github.com/llvm/llvm-project/pull/186215/ It also adds the
`storeMatrixArrayFromVector`. to
SPIRVLegalizePointerCast.cpp when we detect the matrix array of vector
memory layout
Changes to storeArrayFromVector were cleanup

[RISCV] Allocate feature bits for Zifencei and Zmmul (#143306)
As proposed in
https://github.com/riscv-non-isa/riscv-c-api-doc/pull/110.
No real compiler-rt implementation as Linux does not list these
extensions in hwprobe.

[libc][docs] Parse inline macro_value from YAML in docgen (#189118)
The docgen script was previously hardcoded to assume all implemented
macros must be placed in a *-macros.h header. This updates docgen to
read inline macro_value properties directly from the source YAML files,
correctly recognizing them as implemented.
[AArch64][llvm] Separate TLBI-only feature gating from TLBIP aliases
Refactor the TLBI system operand definitions so that TLBI and TLBIP
records are emitted through separate helper multiclasses, whilst keeping
the table layout readable.
The feature-scoped wrappers now apply FeatureTLB_RMI, FeatureRME, and
FeatureTLBIW only to TLBI records (it was previously incorrectly also
applied to TLBIP instructions), while TLBIP aliases remain gated only
by FeatureD128, including their nXS forms.
Update testcases accordingly.
[AArch64][llvm] Rewrite the TLBI multiclass to be much clearer (NFC)
The `tlbi` multiclass is really doing four jobs at once: base TLBI,
synthesized nXS, optional TLBIP, and synthesized TLBIP nXS. Also,
`needsreg` and `optreg` are really just a 3-state operand policy in
disguise. Likewise, the PLBI multiclass has this same issue.
Change `needsreg` and `optreg` into a combined fake enum, so it's
clearer whether the instruction takes no register operand, a required
register operand or an optional register operand.
This improves on my original change 66e8270e8.
[libc] Add missing POSIX macros to cpio.h (#188840)
Define the POSIX cpio.h header and its standard macros in the libc build
system. Configure the macros directly in the YAML specification to allow
automated header generation without a custom definition template.
