Methods

¶RISCVTargetInfo(const llvm::Triple& Triple,
                const clang::TargetOptions&)

Declared at: clang/lib/Basic/Targets/RISCV.h:33

Parameters

const llvm::Triple& Triple

const clang::TargetOptions&

¶std::string convertConstraint(
    const char*& Constraint) const

Declared at: clang/lib/Basic/Targets/RISCV.h:86

Parameters

const char*& Constraint

¶llvm::StringRef getABI() const

Description

Get the ABI currently in use.

Declared at: clang/lib/Basic/Targets/RISCV.h:53

¶clang::TargetInfo::BuiltinVaListKind
getBuiltinVaListKind() const

Description

Returns the kind of __builtin_va_list type that should be used with this target.

Declared at: clang/lib/Basic/Targets/RISCV.h:59

¶const char* getClobbers() const

Description

Returns a string of target-specific clobbers, in LLVM format.

Declared at: clang/lib/Basic/Targets/RISCV.h:63

¶llvm::StringRef getConstraintRegister(
    llvm::StringRef Constraint,
    llvm::StringRef Expression) const

Description

Extracts a register from the passed constraint (if it is a single-register constraint) and the asm label expression related to a variable in the input or output list of an inline asm statement. This function is used by Sema in order to diagnose conflicts between the clobber list and the input/output lists.

Declared at: clang/lib/Basic/Targets/RISCV.h:65

Parameters

llvm::StringRef Constraint

llvm::StringRef Expression

¶int getEHDataRegisterNumber(
    unsigned int RegNo) const

Description

Return the register number that __builtin_eh_return_regno would return with the specified argument. This corresponds with TargetLowering's getExceptionPointerRegister and getExceptionSelectorRegister in the backend.

Declared at: clang/lib/Basic/Targets/RISCV.h:72

Parameters

unsigned int RegNo

¶ArrayRef<TargetInfo::GCCRegAlias>
getGCCRegAliases() const

Declared at: clang/lib/Basic/Targets/RISCV.h:81

¶ArrayRef<const char*> getGCCRegNames() const

Declared at: clang/lib/Basic/Targets/RISCV.h:70

¶ArrayRef<Builtin::Info> getTargetBuiltins() const

Description

Return information about target-specific builtins for the current primary target, and info about which builtins are non-portable across the current set of primary and secondary targets.

Declared at: clang/lib/Basic/Targets/RISCV.h:57

¶void getTargetDefines(
    const clang::LangOptions& Opts,
    clang::MacroBuilder& Builder) const

Description

Appends the target-specific # define values for this target set to the specified buffer.

Declared at: clang/lib/Basic/Targets/RISCV.h:54

Parameters

const clang::LangOptions& Opts

clang::MacroBuilder& Builder

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

Description

Perform initialization based on the user configured set of features.

Declared at: clang/lib/Basic/Targets/RISCV.h:95

Parameters

std::vector<std::string>& Features

clang::DiagnosticsEngine& Diags

¶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/RISCV.h:98

¶bool hasFeature(llvm::StringRef Feature) const

Description

Return true if has this feature, need to sync with handleTargetFeatures.

Declared at: clang/lib/Basic/Targets/RISCV.h:93

Parameters

llvm::StringRef Feature

¶bool initFeatureMap(
    llvm::StringMap<bool>& Features,
    clang::DiagnosticsEngine& Diags,
    llvm::StringRef CPU,
    const std::vector<std::string>& FeaturesVec)
    const

Description

Initialize the map with the default set of target features for the CPU this should include all legal feature strings on the target.

Declared at: clang/lib/Basic/Targets/RISCV.h:89

Parameters

llvm::StringMap<bool>& Features

clang::DiagnosticsEngine& Diags

llvm::StringRef CPU

const std::vector<std::string>& FeaturesVec

Returns

False on error (invalid features).

¶bool setCPU(const std::string& Name)

Description

Target the specified CPU.

Declared at: clang/lib/Basic/Targets/RISCV.h:46

Parameters

const std::string& Name

Returns

False on error (invalid CPU name).

¶bool useFP16ConversionIntrinsics() const

Description

Check whether llvm intrinsics such as llvm.convert.to.fp16 should be used to convert to and from __fp16. FIXME: This function should be removed once all targets stop using the conversion intrinsics.

Declared at: clang/lib/Basic/Targets/RISCV.h:100

¶bool validateAsmConstraint(
    const char*& Name,
    TargetInfo::ConstraintInfo& Info) const

Declared at: clang/lib/Basic/Targets/RISCV.h:83

Parameters

const char*& Name

TargetInfo::ConstraintInfo& Info
