[clang] Use llvm::equal (NFC) (#169172)

2025-11-22T23:30:35+00:00

Identified with llvm-use-ranges.

[clang][NFC] Inline Frontend/FrontendDiagnostic.h -> Basic/DiagnosticFrontend.h (#162883)

2025-11-21T03:39:49+00:00

d076608d58d1ec55016eb747a995511e3a3f72aa moved some deps around to avoid
cycles and left clang/Frontend/FrontendDiagnostic.h as a shim that
simply includes clang/Basic/DiagnosticFrontend.h. This PR inlines it so
that nothing in tree still includes clang/Frontend/FrontendDiagnostic.h.

Doing this will help prevent future layering issues. See #162865.

Frontend already depends on Basic, so no new deps need to be added
anywhere except for places that do strict dep checking.

[Clang] Refactor getOptimizationLevel and getOptimizationLevelSize to non-static. NFC. (#168839)

2025-11-21T01:15:40+00:00

So that we can reuse these functions in few place, such as in
clang/lib/Driver/ToolChains/CommonArgs.cpp. Part of the code there is
currently copied from getOptimizationLevel.

[clang] Add a TODO for output paths in invocation path visitation (#167983)

[clang] Extract `CompilerInvocation::visitPaths()` (#167420)

2025-11-12T22:20:53+00:00

This PR extracts visitation of paths stored in `CompilerInvocation` into
a member function. We already have a second copy of this downstream, and
I'm in the need of adding a third one.

Reland "[clang] Refactor option-related code from clangDriver into new clangOptions library" (#167374)

2025-11-10T20:24:39+00:00

This relands #167348.

The original PR was reverted due to a reported build failure, which was
later diagnosed as a local issue in the developer’s checkout or build
state. See discussion here:
https://github.com/llvm/llvm-project/pull/163659#discussion_r2511546964

No additional changes have been made in this reland.

Revert "[clang] Refactor option-related code from clangDriver into new clangOptions library" (#167348)

2025-11-10T17:27:20+00:00

Reverts #163659 due to missing one reference clang/Driver/Options.h in 
clang/include/clang/Driver/Driver.h.

[clang] Refactor option-related code from clangDriver into new clangOptions library (#163659)

2025-11-10T16:19:03+00:00

This change moves option-related code from clangDriver into a new
clangOptions library.

This refactoring is part of a broader effort to support driver-managed
builds for compilations using C++ named modules and/or Clang modules.
It is required for linking the dependency scanning tooling against the
driver without introducing cyclic dependencies, which would otherwise
cause build failures when dynamic linking is enabled.
In particular, clangFrontend must no longer depend on clangDriver
for this to be possible.

This PR is motivated by the following review comment:

[ADT] Prepare to deprecate variadic `StringSwitch::Cases`. NFC. (#166020)

2025-11-02T00:12:33+00:00

Update all uses of variadic `.Cases` to use the initializer list
overload instead. I plan to mark variadic `.Cases` as deprecated in a
followup PR.

For more context, see https://github.com/llvm/llvm-project/pull/163117.

[HLSL] Add NativeInt16Type langopt to control whether short type is supported. Enabled by default for all but HLSL. (#165584)

2025-10-31T16:49:32+00:00

Add a new langopt NativeInt16Type to control support for 16 bit
integers.
Enable by default for all languages but HLSL. 
HLSL defines uint16_t and int16_t as a typedef of short. If
-enable-16bit-types is not used, the typedefs don't exist so int16_t and
uint16_t can't be used. However, short was still allowed. This change
will produce an error 'unknown type name short' if -enable-16bit-types
isn't used.
Update failing tests. 
Add new test.
Closes #81779
