Updating test clang/test/Driver/driverkit-path.c for usage with CLANG_RESOURCE_DIR (#197154)
When the CMake option CLANG_RESOURCE_DIR is specified, it changes
the path to various tools and thus breaks some tests that look for things
in the "standard" location. This change updates one of the tests to take
into account the CLANG_RESOURCE_DIR value if specified by querying
compiler using `-print-resource-dir` to more accurately find the expected
directory in tests.
[flang][CUDA] Allocate converted kernel descriptors in device-accessible storage (#201950)
Fix CUDA descriptor lowering when an `fir.embox` result reaches a
`gpu.launch_func` through an intermediate `fir.convert`.
CodeGen previously failed to recognize this use chain and could place
the descriptor in host stack storage. Since CUDA kernels may dereference
assumed-shape descriptors on the device, such descriptors must be
allocated through the CUDA descriptor allocation path. Teach the
GPU-launch-use check to look through `fir.convert` so these descriptors
are lowered with `_FortranACUFAllocDescriptor`.
Also adds a regression test for the `fir.embox -> fir.convert ->
gpu.launch_func` case.
CI: move libclang python byindings tests to main CI
This removes the separate python bindings CI, which run on the GitHub free
runners and take more than one hour to build libclang.
The tests are executed instead in the monolithic pipelines,
whenever clang would be tested.
This is fine in terms of resources because all the dependencies are
built anyway, and the tests themselves take less than one second to
run on the free runners.
[clang] Reland: fix getTemplateInstantiationArgs (#202088)
Relands https://github.com/llvm/llvm-project/pull/199528
Previous: #201373
This implements a new strategy for collecting the template arguments, by
relying on the qualifiers and template parameter lists to navigate the
template
context of out-of-line definitions.
This greatly simplifies the signature of that function, by removing a
bunch
of workarounds, and simpliffying a couple that weren't removed yet.
Since this now relies on qualifiers and template parameter lists,
this patch expends most of its effort making sure these are placed,
transformed and propagated to template instantiations.
Also makes the explicit specialization AST nodes stop abusing the

[ADT] Remove unused DenseMapInfo::getEmptyKey (#201998)
After #201281 DenseMapInfo<T>::getEmptyKey() is no longer used by
DenseMap. Remove the unused getEmptyKey definitions and dead sentinel
uses.
[libc][math] Fix arm-linux-gnueabihf target when building with gcc/g++. (#202090)
- `arm-linux-gnueabihf-gcc` defines fixed point macros (like
`__FRACT_FBIT__`) but does not support `_Fract` and `_Accum` types by
default. We just limit the fixed point support to clang for now.
- Specify the types for the sqrt instructions we use for ARM target.
Tested with:
```
$ cmake ../runtimes -GNinja -DLLVM_ENABLE_RUNTIMES=libc -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc-12 \
-DCMAKE_CXX_COMPILER=arm-linux-gnueabihf-g++-12 \
-DLIBC_TARGET_TRIPLE=arm-linux-gnueabihf
$ export QEMU_LD_PREFIX=/usr/arm-linux-gnueabihf
$ ninja libc-shared-tests

cfi: Include uaccess.h for get_kernel_nofault()
After commit 0652a3daa787 ("tracing: Fix CFI violation in probestub
being called by tprobes"), there are many build errors when building
ARCH=arm multi_v7_defconfig + CONFIG_CFI=y like:
In file included from drivers/base/devres.c:17:
In file included from drivers/base/trace.h:16:
In file included from include/linux/tracepoint.h:23:
include/linux/cfi.h:44:6: error: call to undeclared function 'get_kernel_nofault'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
44 | if (get_kernel_nofault(hash, func - cfi_get_offset()))
| ^
1 error generated.
get_kernel_nofault() is called in the generic version of
cfi_get_func_hash() but nothing ensures uaccess.h is always included for
a proper expansion and prototype. Include uaccess.h in cfi.h to clear
up the errors.

this patch expends most of its effort making sure these are placed,

Also makes the explicit specialization AST nodes stop abusing the template
parameter lists by storing it's own template parameter list, creating a
dedicated field for them, similar to partial specializations.
[clang-doc] Use llvm RTTI over handrolled casting (#202059)
Clang-Doc has a limited amount of polymorphism over Info types.
Historically, these have just been cast directly in a few places, but we
can use the existing llvm RTTI implementation to more rigorously
dispatch and query the types involved with only limited extra code.
This should make future changes a bit harder to get wrong.
[CodeGen][Transforms] Remove unused DenseMapInfo::getEmptyKey (#201994)

[SLP]Keep reuse mask in sync when reordering split node operand
When reorderBottomToTop uses an operand order for a split vectorize
node and the operand has both reordered and reused scalars, only the
reorder indices were cleared while the reuse mask was left stale. This
diverged the split node scalars from the operand effective order.
Fixes #202003
