◆ getBuiltinVaListKind()

BuiltinVaListKind clang::targets::CSKYTargetInfo::getBuiltinVaListKind ( ) const

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

Implements clang::TargetInfo.

Definition at line 78 of file CSKY.h.

◆ getClobbers()

std::string_view clang::targets::CSKYTargetInfo::getClobbers ( ) const

◆ getMinGlobalAlign()

unsigned CSKYTargetInfo::getMinGlobalAlign ( uint64_t  Size,
bool  HasNonWeakDef 
) const
overridevirtual

getMinGlobalAlign - Return the minimum alignment of a global variable, unless its alignment is explicitly reduced via attributes.

If

Parameters
HasNonWeakDefis true, this concerns a VarDecl which has a definition in current translation unit and that is not weak.

Reimplemented from clang::TargetInfo.

Definition at line 311 of file CSKY.cpp.

◆ getTargetBuiltins()

ArrayRef< Builtin::Info > CSKYTargetInfo::getTargetBuiltins ( ) const
overridevirtual

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.

Implements clang::TargetInfo.

Definition at line 142 of file CSKY.cpp.

◆ getTargetDefines()

void CSKYTargetInfo::getTargetDefines ( const LangOptions Opts,
MacroBuilder Builder 
) const
overridevirtual

===-— Other target property query methods -----------------------—===//

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

Implements clang::TargetInfo.

Definition at line 34 of file CSKY.cpp.

References ABI, Arch, CPU, DSPV2, HardFloat, is3E3R1, VDSPV1, and VDSPV2.

◆ handleTargetFeatures()

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

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.

Returns
False on error.

Reimplemented from clang::TargetInfo.

◆ hasBitIntType()

bool clang::targets::CSKYTargetInfo::hasBitIntType ( ) const
inlineoverridevirtual

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.

Reimplemented from clang::TargetInfo.

Definition at line 96 of file CSKY.h.

◆ hasFeature()

bool CSKYTargetInfo::hasFeature ( StringRef  Feature) const
overridevirtual

Determine whether the given target has the given feature.

bool CSKYTargetInfo::isValidCPUName ( StringRef  Name) const
overridevirtual

Determine whether this TargetInfo supports the given CPU name.

Reimplemented from clang::TargetInfo.

Definition at line 18 of file CSKY.cpp.

◆ setABI()

inlineoverridevirtual

Use the specified ABI.

Returns
False on error (invalid ABI name).

Definition at line 62 of file CSKY.h.

◆ setCPU()

bool CSKYTargetInfo::setCPU ( const std::string &  Name)
overridevirtual

Target the specified CPU.

False on error (invalid CPU name).
