[PseudoProbe] Support loading pseudo probe from debug binary (#175698)
Pseudo probe and DWARF sections can occupy a significant amount of space
in binary for large application. An executable PE image file should not
be larger than 2GB on Windows. To support LBR collection for those large
applications, user can use llvm-objcopy to strip those debug sections
and produce a smaller binary for profiling. The original binary can then
be used as the debug binary to load pseudo probe and DWARF info.
[LTOBackend] Add -filter-save-modules= for save-temps to only dump specific modules. (#175696)
Only if module's name contains a string in -filter-save-modules, will
its temp BC files be saved. If -filter-save-modules= not set, all
modules' BC files will be saved. This feature is more useful for ThinLto
when huge numbers of modules are built separately. Using
-filter-save-modules= can reduce build time and size of generated files,
even avoid crash if some other unrelated files have issues during BC
files dumping.
[X86][APX] Ignore the use of EFLAGS when ZU is enabled (#176645)
Since we don't need to insert the XOR instruction.

[mlir][memref] Support folding memref.load from global splat constants (#176627)
This change extends the memref.load folding hook to fold loads from
global constant memrefs initialized with splat values.
[clang-tidy] Add documentation and smoke test for CUDA (#173699)
As of AI usage: Gemini 3 was used to refine the wording and style of the
documentation text.
Closes #173677
port the __c99_cabs*() rename fixes into GCC 12.
almost identical to the GCC 14 version, riscv-builtins.cc needed a new
#include of tm_p.h to get netbsd-protos.h.

[VPlan] Support more GEP-like recipes in getSCEVExprForVPValue (NFCI)
Support VPWidenGEPRecipe, VPInstructions and VPRelpicateRecipe with
GEP-like opcodes in getSCEVExprForVPValue via a new matcher binding
source element type and operands.
This is used in code paths when computing SCEV expressions in the
VPlan-based cost model, which should produce costs matching the legacy
cost model.
[X86] Simplify hasCalleePopSRet, NFCI (#176519)
The implementation was rewritten for clarity, and the extra boolean
parameter to the sibcall eligibility check was removed in favor of
recalculating this property. The compile time impact should be
negigible, the vast majority of callers will return early on the
TT.isX86_32() check.
The comments now try to clarify which platforms have this
callee-pop-sret behavior, which was always hard for me to figure out
from the previous code.
I was able to remove two ambiguous checks for `canGuaranteeTCO`, and
what those checks were really doing was checking for `fastcc` and other
calling conventions that pass arguments in registers. Instead of looking
for the `inreg` IR attribute, now the code looks at the CCValAssign to
check if it the pointer is passed in memory or registers, so it works
smoothly with conventions like `fastcc` that don't require explicit
`inreg` annotations.
