¶void adjust(clang::DiagnosticsEngine& Diags,
            clang::LangOptions& Opts)

Description

Set forced language options. Apply changes to the target information with respect to certain language options which change the target configuration and adjust the language based on the target options where applicable.

Declared at: clang/lib/Basic/Targets/PPC.h:99

Parameters

clang::DiagnosticsEngine& Diags

clang::LangOptions& Opts

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

Declared at: clang/lib/Basic/Targets/PPC.h:320

Parameters

const char*& Constraint

¶void fillValidCPUList(
    SmallVectorImpl<llvm::StringRef>& Values)
    const

Description

Fill a SmallVectorImpl with the valid values to setCPU.

Parameters

SmallVectorImpl<llvm::StringRef>& Values

¶llvm::StringRef getABI() const

Description

Get the ABI currently in use.

Declared at: clang/lib/Basic/Targets/PPC.h:177

¶const char* getClobbers() const

Description

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

Declared at: clang/lib/Basic/Targets/PPC.h:335

¶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/PPC.h:336

Parameters

unsigned int RegNo

¶const char* getFloat128Mangling() const

Description

Return the mangled code of __float128.

Declared at: clang/lib/Basic/Targets/PPC.h:353

¶ArrayRef<TargetInfo::AddlRegName>
getGCCAddlRegNames() const

Declared at: clang/lib/Basic/Targets/PPC.h:206

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

Declared at: clang/lib/Basic/Targets/PPC.h:204

¶ArrayRef<const char*> getGCCRegNames() const

Declared at: clang/lib/Basic/Targets/PPC.h:202

¶const char* getIbm128Mangling() const

Description

Return the mangled code of __ibm128.

Declared at: clang/lib/Basic/Targets/PPC.h:354

¶const char* getLongDoubleMangling() const

Description

Return the mangled code of long double.

Declared at: clang/lib/Basic/Targets/PPC.h:346

¶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/PPC.h:179

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

Description

PPCTargetInfo::getTargetDefines - Return a set of the PowerPC-specific #defines that are not tied to a specific subtarget.

Declared at: clang/lib/Basic/Targets/PPC.h:183

Parameters

const clang::LangOptions& Opts

clang::MacroBuilder& Builder

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

Description

handleTargetFeatures - Perform initialization based on the user configured set of features.

Declared at: clang/lib/Basic/Targets/PPC.h:194

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/PPC.h:356

¶bool hasFeature(llvm::StringRef Feature) const

Description

Determine whether the given target has the given feature.

Declared at: clang/lib/Basic/Targets/PPC.h:197

Parameters

llvm::StringRef Feature

¶bool hasSjLjLowering() const

Description

Controls if __builtin_longjmp / __builtin_setjmp can be lowered to llvm.eh.sjlj.longjmp / llvm.eh.sjlj.setjmp.

Declared at: clang/lib/Basic/Targets/PPC.h:344

¶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/PPC.h:187

Parameters

llvm::StringMap<bool>& Features

clang::DiagnosticsEngine& Diags

llvm::StringRef CPU

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

Returns

False on error (invalid features).

¶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/PPC.h:181

¶bool isSPRegName(llvm::StringRef RegName) const

Declared at: clang/lib/Basic/Targets/PPC.h:358
