Git commit 6a932c6041a58a1c352ea65c94810a13d3b453d0 by GitHub (on behalf of janr-bay) on 30/07/2026 at 11:25..
[APFloat][NFC] Generalize bitcast to also cover x87 semantics (#209781)

This removes the special case code for bitcasting APInt to a float with
x87 semantics in convertF80LongDoubleAPFloatToAPInt. This makes it
consistent with previous removal of special cases and will remove one
more small obstacle to making APFloat extensible.

[libc++] Clean up windows macros (#207577)

We have multiple macros for different Windows. However, most of them
don't actually define different things. We can condense the macros to
- `_WIN32` directly if it only depends on windows, or
- `_LIBCPP_MSVCRT`

This patch drops `_LIBCPP_MSVCRT_LIKE` and `_LIBCPP_WIN32API`, since
they are equivalent to `_WIN32`.

libc++abi is very close to libc++, and even shares some amount of code.
We should keep the formatting style the same between the two libraries.

clang/AMDGPU: Forward xnack/sramecc mode to the assembler (#212955)

When assembling a .s file with no target ID directive, the requested
xnack/sramecc mode has no module flag to carry it. Forward the mode
requested via -mxnack/-msramecc (or the -mcpu target ID modifiers) to
the assembler as a target feature so it is recorded in the object's e_flags.

[OFFLOAD] Fix a platform selection issue for llvm-gpu-loader (#212893)

Currently if an image supplied to llvm-gpu-loader is not properly
detected by its platform detection logic it does not accept it for
execution. The example could be a spirv or bitcode format. This fix
allows it to rely on devices to device if an image will be accepted and
uses its existing platform detection logic as an optimization only

[llvm-calc-occupancy] Add an AMDGPU occupancy calculator tool (#208727)

Add a command-line utility that reports the occupancy (waves/EU) an
AMDGPU kernel would reach for a given workgroup size, VGPR/SGPR usage
and LDS. It reuses the backend's own occupancy math, so the numbers
match the compiler. Includes a lit test and a CommandGuide man page.

[flang] Delete the array-value-copy pass (#212643)

Since the removal of the legacy expression lowering (#210385, #210621,
#210639, #210873) nothing in flang produces the array-value operations
this pass legalizes, and #211816 already removed it from the default
pipeline. Delete the pass and the pieces that existed solely for it:

- ArrayValueCopy.cpp, its Passes.td definition,
createArrayValueCopyPass, and the (duplicated) CMake source entries.
- Optimizer/Builder/Factory.h in its entirety: the pass was its only
includer, and its contents (attrFortranArrayOffsets,
getExtents/getOrigins on shape values, originateIndices) have no other
users.
- The getTypeParams(fir::ArrayLoadOp) overload (sole caller was the
pass) and the ArrayLoadOp forward declaration in BoxValue.h.
- The pass LIT tests (array-value-copy*.fir, array-copies-pointers.fir,
array-modify.fir); stack-arrays-hlfir.f90 drops the --array-value-copy
stage from its RUN pipeline.
- The pass-describing paragraphs in fstack-arrays.md and the stale
ArrayValueCopy TODO entry in ParameterizedDerivedTypes.md.

The array-value operations themselves (fir.array_load and friends; not
fir.array_coor) remain in the dialect and will be deleted in a
follow-up.

[libc][cmake] Make hermetic tests support FLAGS (#212460)

Currently the tests skip themselves because this gets treated as a
(missing) dependency.

I also enable tests that were explicitly skipped with UNIT_TEST_ONLY.
Some of the FP tests are claiming to be failing on GPUs (in 2023). If
that is still true, I'll skip them with if(TARGET_IS_GPU).

[libc][test] Add EXPECT_STREQ and ASSERT_STREQ macros for integration tests (#212729)

Add EXPECT_STREQ and ASSERT_STREQ macros to IntegrationTest/test.h using
cpp::string_view. Note that, unlike the unit test macro (but like
googletest), this version treats NULL as distinct from "". The
inconsistency is unfortunate, but I think it's important as the code is
used for testing functions like getenv(), where "" and NULL have very
different meanings.

We should probably follow this up with a change to make the unit test
macro behave the same way.

Update integration tests to use the new macros instead of handrolled
string equality functions (my_streq), strcmp, inline_strcmp, or
string_view wrappers.

[libc] Move test macro implementations out of the Test class (#212783)

This is useful for several reasons:
- it makes it possible to use the macros outside of the test methods,
aligning with googletest. Although this isn't recommended, the
alternatives are often not worth it.
- it makes it possible (with additional changes) to expose this
infrastructure to C_TESTs (which currently use the assert() macro, which
is a no-op in release mode)
- it makes it possible to add (and have assertions in) googletest style
SetUp/TearDownTestSuite functions.

I've converted the main assertion macros for now, to test the waters.
I'm planning to handle EXPECT/ASSERT_THAT and EXPECT/ASSERT_EXIT/DEATH
in a follow-up.

[SPIRV] Emit NonSemantic DebugTypedef (#211883)

This adds `DebugTypedef` emission to the SPIR-V
NonSemantic.Shader.DebugInfo handler.

`SPIRVNonSemanticDebugHandler` now collects `DIDerivedType` nodes tagged
`DW_TAG_typedef` and emits one `DebugTypedef` per node. The emitter
reuses the handler's type-id map and skips a typedef whose base type was
not emitted.

This one has similar limitations to the other type emitters (tracked in
#211850)

1. Typedefs are emitted in one `DebugInfoFinder`-order pass, so a
typedef whose base is another typedef emitted later in that pass is
dropped.
2. The Parent operand uses the enclosing type's id when the typedef's
scope is an emitted `DIType`, otherwise the compile unit. On its own
this PR emits no type that can be a typedef's scope. I'll address this
after debug info for composite types is in mainline.

Tests:

1. `debug-typedef.ll` covers a file-scope typedef of `int` parented to
the compile unit, checking all six operands.
2. `debug-typedef-skip-base-not-in-regs.ll` covers the skip path with a
typedef of a pointer that has no DWARF address space.
3. `debug-typedef-nested-drop.ll`: tests the one-pass limitation: a
two-level typedef emits one `DebugTypedef`, with
`--implicit-check-not=DebugTypedef`.
