[NewPM] Port x86-winehstate (#180687)
x86-winehstate has been converted to a module pass for NewPM since it
uses data from the Module by overriding `doInitialization` and
`doFinalization`.
[AMDGPU] [GlobalIsel] Enabling lit tests for new regbank select (#180680)
This patch will enable few more lit tests that depends on G_FRAME_INDEX
opcode.
[clang] Ensure -mno-outline adds attributes
Before this change, `-mno-outline` and `-moutline` only controlled the
pass pipelines for the invoked compiler/linker.
The drawback of this implementation is that, when using LTO, only the
flag provided to the linker invocation is honoured (and any files which
individually use `-mno-outline` will have that flag ignored).
This change serialises the `-mno-outline` flag into each function's
IR/Bitcode, so that we can correctly disable outlining from functions in
files which disabled outlining, without affecting outlining choices for
functions from other files. This matches how other optimisation flags
are handled so the IR/Bitcode can be correctly merged during LTO.
[clang] Add clang::nooutline Attribute
This change:
- Adds a `[[clang::nooutline]]` function attribute for C and C++. There
is no equivalent GNU syntax for this attribute, so no `__attribute__`
syntax.
- Uses the presence of `[[clang::nooutline]]` to add the `nooutline`
attribute to IR function definitions.
- Adds test for the above.
The `nooutline` attribute disables both the Machine Outliner (enabled at
Oz for some targets), and the IR Outliner (disabled by default).
[outliners] Turn nooutline into an Enum Attribute
This change turns the `"nooutline"` attribute into an enum attribute
called `nooutline`, and adds an auto-upgrader for bitcode to make the
same change to existing IR.
This IR attribute disables both the Machine Outliner (enabled at Oz for
some targets), and the IR Outliner (disabled by default).

[CIR] Add static_local attribute to GlobalOp and GetGlobalOp
This attribute marks function-local static variables that require
guarded initialization (e.g., C++ static local variables with
non-constant initializers). It is used by CIRGen to communicate
to LoweringPrepare which globals need guard variable emission.
[flang] Don't do actual concatenation when computing LEN() of concatenated strings (#180676)
For cases like the following don't actually compute concatenation of
`str // "abc"`, because we only need final length:
```
character(len=*), intent(in) :: str
character(len=len(str // "abc")) :: res
```
For such cases, don't emit hlfir.concat.
Fixes #157763
[CIR] Add ASTVarDeclInterface for AST attribute access
Add the ASTVarDeclInterface which provides methods to access clang AST
VarDecl information from CIR attributes. This interface enables:
- mangleStaticGuardVariable: Mangle guard variable names using clang's
MangleContext
- isLocalVarDecl: Check if a variable is function-local
- getTLSKind: Get thread-local storage kind
- isInline: Check if the variable is inline
- getTemplateSpecializationKind: Get template specialization info
- getVarDecl: Direct access to the underlying VarDecl pointer
This infrastructure is needed for proper handling of static local
variables with guard variables in LoweringPrepare.

[SimplifyCFG][PGO] Add missing overflow check to ConstantFoldTerminator (#178964)
Branch weight metadata can overflow when folding large branch weights.
Updated branch weights to uint64_t, added check for overflow, and then
set branch weights using setFittedBranchWeights to ensure branch weight
metadata is not lost.
pfr_attach_table() needs wait flag.
Calling pool_get() without wait flag is not allowed. pf(4) ioctl
has to use PR_WAITOK in pf_sourcelim_add().

- Provide the missing 64-bit variant of clock_getres()
This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
finally the removal of 32-bit time types from the kernel and UAPI.
- Remove the useless and broken getcpu_cache from the VDSO
The intention was to provide a trivial way to retrieve the CPU number
from the VDSO, but as the VDSO data is per process there is no way to
make it work.
- Switch get/put_unaligned() from packed struct to memcpy()
The packed struct violates strict aliasing rules which requires to
pass -fno-strict-aliasing to the compiler. As this are scalar values
