[RISCV] Force a frame pointer when the max reserved call frame exceeds simm12. (#182124)
We need to be able to address emergency spill slots without requiring a
register scavenging. This requires the emergency spill slot to be near
the SP or the FP to keep the offset small enough. If there is a large
reserved call frame, we can't keep the emergency spill slot near SP. But
we might not have a frame pointer.
This patch forces the use of a frame pointer when the max reserved call
frame is large so we can keep the emergency spill slot near it. This
idea is borrowed from AArch64.
Multiple MIR tests had to be updated to set the max call frame size as
the reserved registers are frozen before mirFileLoaded is called. I
copied mirFileLoaded from AArch64, but it appears the register freezing
moved after the AArch64 code was written.
Fixes #180199.
[LSR][RISCV] Add support for cmp/branch fuse.
RISCV has cmp within branches, and therefore
costing using cmp/branch fuse in LSR is
useful to configure the proposed solution
cost for LSR.
[MLIR][tblgen] Honor `-dialect` in `-gen-{attrdef,op,typedef,enum}-doc`
Make all dialect documentation generators use the same set of records as
`-gen-dialect-doc`, which honors the `-dialect` tblgen option to filter
records by dialect. Add a `-keep-op-source-order` option to allow
`-gen-op-doc` to continue producing unsorted op lists if needed.
This commit factors the record collection, filtering, and sorting
performed in `emitDialectDoc` out into a separate `collectRecords`
function, returning a `DialectRecords` with the results. The emit
functions now all accept a `DialectRecords` argument instead of
collecting records themselves. Most changes are mechanical renamings and
moving code around.
This fixes a confusing issue where `gen-dialect-doc` would produce the
entire documentation for a dialect, but individual calls to
`gen-attrdef-doc` and the like would seemingly operate on a different
set of records, potentially covering multiple dialects. This all produce
the overall documentation now.
[modules] Move diagnostic about specific mtime/size change into a note from an error. (#181963)
So far higher visibility is more confusing than actionable. Keep the
information available but make it less prominent.

[SDPatternMatch] Support conditionally binding the value matching a sub-pattern (#182091)
I've seen more and more occurrences of what is essentially
```
m_AllOf(<sub pattern>, m_Value(BindVal))
```
That is, bind to the same SDValue that matches the sub-pattern. Most
people won't even bother write this `m_AllOf` construct because it's too
long, and instead just write another `sd_match` against the bound value.
This patch adds
```
m_Value(BindVal, <sub pattern>)
```
To replace the `m_AllOf` construct above and conditionally bind the
SDValue that matches the sub-pattern.

[OpenMP] Remove standalone build mode (Reapply #149878) (#182022)
This reapplies #149878
Remove all the CMake code for openmp standalone builds. Standalone
builds have been superseded by the runtimes default build (also
sometimes called the standalone runtimes build). The runtimes default
build can be thought of a standalone build with the standalone
boilerplate contained in <llvm-project>/runtimes/CMakeLists.txt. There
is no need for each runtime to contain the same boilerplate code again.
Builds still using the standalone build via
```sh
cmake -S <llvm-project>/openmp ...
```
can switch over to the runtimes default build using
```sh
cmake -S <llvm-project>/runtimes -DLLVM_ENABLE_RUNTIMES=openmp ...
```

[clang][DependencyScanning] Use OverlayFS naming consistently [NFC] (#172352)
Changes the naming of the OverlayFileSystem parameter for more consistent use in
`DependencyScanningTool.cpp`.

[CIR][CodeGen] Use MapVector instead of StringMap for replacements (#181969)
When using llvm::StringMap transitive replacements may be out of order, so use llvm::MapVector which is also used in Clang's LLVM IR CodeGen.
[clang] Make makeInputArg available in Driver.h [NFC] (#182163)
This moves makeInputArg from Driver.cpp to Driver.h so it can be used by
other components.
This change is part of an effort to split #152770 into smaller, more
manageable pieces.
[clang][darwin] macOS no longer infers a minimum deployment version from the OS version (#181958)
The recent createFromSDKInfo refactor lost the
getSystemOrSDKMacOSVersion version adjustment on macOS, causing -arch

[clang] Move InputTy and InputList out of the Driver class [NFC] (#182158)
This change moves InputTy and InputList outside of the Driver class to
allow wider usage.
InputTy and InputList are currently defined inside the Driver class,
which prevents other headers from using them without including Driver.h
(by foreward declaring).
This change is required for #152770 and is part of an effort to break
that PR into smaller pieces.
[flang][acc] Add ACCDeclareActionConversion pass (#181894)
Implements the allocation and deallocation semantics for allocatables
and pointers in declare directives (OpenACC 3.4, Section 2.13.2). For a
non-shared memory device, allocate/deallocate must keep local and device
memory in sync.
Lowering generates recipe functions (with acc dialect ops to create the
device copy) and attaches an attribute to the operations that allocate
or deallocate the object. This pass finds those operations and inserts
calls to the corresponding recipe.
Example: for "!$acc declare create(arr)" and "allocate(arr(100))" in a
subroutine, the pass inserts a call to the post-alloc recipe after the
store so the device copy is created.

clang: normalise directory cache keys consistently in `FileManager` (#181306)
Extract the directory path normalisation logic into a shared
`normalizeCacheKey` helper and apply it in `addAncestorsAsVirtualDirs`
in addition to `getDirectoryRef`. This ensures that cache lookups and
insertions use a consistent key at all call sites.

[offload][lit] Enable/disable tests on Level Zero when using DeviceRTL (#182128)
Since we can now build the DeviceRTL with SPIR-V, redo the
`XFAIL/UNSUPPORTED` specifications for the tests we see passing/failing
on the Level Zero backend with the DeviceRTL being used.
The tests marked `UNSUPPORTED` hang or sporadically fail and those are
tracked in https://github.com/llvm/llvm-project/issues/182119.
This change will allow us to enable CI testing with the DeviceRTL.
Here are the full test results with this change applied, running only
the `spirv64-intel` `check-offload` tests:
```
Total Discovered Tests: 453
Unsupported : 206 (45.47%)
Passed : 141 (31.13%)
Expectedly Failed: 106 (23.40%)

[libc] Modular printf option (float only)
This adds LIBC_CONF_PRINTF_MODULAR, which causes floating point support
(later, others) to be weakly linked into the implementation.
__printf_modular becomes the main entry point of the implementaiton, an
printf itself wraps __printf_modular. printf it also contains a
BFD_RELOC_NONE relocation to bring in the float aspect.
See issue #146159 for context.
