getVScaleRange(
    const clang::LangOptions& LangOpts) const

Description

Parameters

const clang::LangOptions& LangOpts

bool handleTargetFeatures(
    std::vector<std::string>& Features,
    clang::DiagnosticsEngine& Diags)

Description

Perform initialization based on the user configured set of features (e.g., +sse4). The list is guaranteed to have at most one entry per feature. The target may modify the features list, to change which options are passed onwards to the backend. FIXME: This part should be fixed so that we can change handleTargetFeatures to merely a TargetInfo initialization routine.

Declared at: clang/lib/Basic/Targets/AArch64.h:116

Parameters

std::vector<std::string>& Features
clang::DiagnosticsEngine& Diags

Returns

False on error.

bool hasBitIntType() const

Description

Determine whether the _BitInt type is supported on this target. This limitation is put into place for ABI reasons. FIXME: _BitInt is a required type in C23, so there's not much utility in asking whether the target supported it or not; I think this should be removed once backends have been alerted to the type and have had the chance to do implementation work if needed.

Declared at: clang/lib/Basic/Targets/AArch64.h:159

bool hasFeature(llvm::StringRef Feature) const

Description

Determine whether the given target has the given feature.

Declared at: clang/lib/Basic/Targets/AArch64.h:115

Parameters

llvm::StringRef Feature

bool hasInt128Type() const

Description

Determine whether the __int128 type is supported on this target.

Declared at: clang/lib/Basic/Targets/AArch64.h:157

bool isCLZForZeroUndef() const

Description

The __builtin_clz* and __builtin_ctz* built-in functions are specified to have undefined results for zero inputs, but on targets that support these operations in a way that provides well-defined results for zero without loss of performance, it is a good idea to avoid optimizing based on that undef behavior.

Declared at: clang/lib/Basic/Targets/AArch64.h:121

Description

Target the specified CPU.

Declared at: clang/lib/Basic/Targets/AArch64.h:77

Returns

False on error (invalid CPU name).
