[HLSL] Add support for groupshared args (#181886)
Add support for groupshared args to HLSL.
Some support for template errors and warnings still needs to be added in
a follow up (tracked by #182535)
Closes #174472
[libunwind][PAC] Defang ptrauth's PC in valid CFI range abort
It turns out making the CFI check a release mode abort causes many,
if not the majority, of JITs to fail during unwinding as they do not
set up CFI sections for their generated code. As a result any JITs
that do nominally support unwinding (and catching) through their JIT
or assembly frames trip this abort.

A bit of MMU handling cleanup:
- BI_MMU_APOLLO does, in fact, mean the Apollo MMU for 68020 used on the
DN3000 and DN4000 machines.
- If we end up with an unknown MMU value, try to reconcile with machine
type and CPU type.
Mk/Uses: Remove certs.mk
It was a useful shorthand for the security/ca_root_nss dependency.
However, several people disagreed.
Can anybody explain why libedit.mk is there? It is also a one string
substitution. Same with libarchive.mk.
[Clang] Track alloca element types to avoid getAllocatedType() calls (#181740)
Store alloca element types alongside alloca pointers in Clang's CodeGen,
eliminating the need to query getAllocatedType() later.
Changes:
- CodeGenFunction.h: Modified DominatingLLVMValue::saved_type to track
type Uses Type==nullptr as sentinel for "not saved" instead of separate
bool. Fixes a bug where it previously tried to use the addrspacecasted
value constructor and later cast it to an alloca.
- CGHLSLRuntime.cpp: Changed OutputSemantic map to store (Value*, Type*)
pairs to trivially remove getAllocatedType calls.

Move virt68k's bootinfo code to a generic m68k location with names
linux_bootinfo.[ch] (since that's what this data is compatible with).
Facilitates use by other m68k platforms in the future.
Also, don't bother installing the header file; nothing in userland needs it.
mk: drop old, now unused version of DTB generation
This was replaced by bsd.dtb.mk back in 2020.
Build-tested on evbarm-aarch64, evbarm-earmv7hf, riscv-riscv64, amd64,
and sparc64.
[DA] Fix overflows when calculating Delta in the Weak Zero SIV tests (#184997)
Add overflow checks when computing `Delta` in the Weak Zero SIV tests.
The tests bail out if we cannot prove that the `Delta` computation does
not overflow. These calculations are also moved later so that some
analyses that do not require these checks can run first.
Fix part of the test cases added in #164246.
Revert "AMDGPU: Annotate group size ABI loads with range metadata (#185420)" (#185521)
This reverts commit 76daf31b4000623d5c9548348a859ea3ed8712e1.
Bot failure.
[lld][MachO] Deduplicate branch-extension thunks for ICF-folded symbols (#185396)
After ICF, multiple symbols may resolve to the same address but remain
as distinct Symbol pointers. When used as keys in thunkMap, this caused
redundant branch-extension thunks to be created for the same target. Fix
this by providing a custom DenseMapInfo for thunkMap that hashes and
compares Defined symbols by (isec, value) instead of pointer identity.
[HLSL] Fix interleaved vector and matrix return types in AST dump (#184888)
HLSL vector and matrix types were previously printed with their closing
syntax (', N>') in 'printAfter', causing them to interleave with
function
parameters when used as return types (e.g., 'vector<float (args), 4>').
This change moves the HLSL vector and matrix closing syntax into
'printBefore' when 'UseHLSLTypes' is enabled, ensuring the type is
printed completely before the parameter list.
Note that address space qualifiers are now printed after the type
(e.g., 'vector<float, 4>hlsl_device'). This is because
'canPrefixQualifiers' in 'TypePrinter.cpp' returns false for these
types.
We cannot easily change this to check 'UseHLSLTypes' because
'canPrefixQualifiers' is a static method and does not have access to the
PrintingPolicy at that point.

[NFC] Migrate NVPTX specific debug info code to separate class
This refactors the dwarf emission code to pull out the rest of the NVPTX specific code into it's own subclass for debug info handling and architecture specific differences.
Tested with ninja check-all on OSX.
Use __pledge_open(2) for files that libc urgently needs even in lower
promise levels. You must be running a kernel at least 4 days old.
Soon, another commit will happen that breaks compatibility even further,
and you'll need new static binaries and new libc.so, along with a new
kernel. This removes an old pledge design decision which is weak.
Long discussions with david leadbeater and beck
