Methods
¶X86_64TargetInfo(const llvm::Triple& Triple,
const clang::TargetOptions& Opts)
X86_64TargetInfo(const llvm::Triple& Triple,
const clang::TargetOptions& Opts)Declared at: clang/lib/Basic/Targets/X86.h:681
Parameters
- const llvm::Triple& Triple
- const clang::TargetOptions& Opts
¶clang::TargetInfo::CallingConvCheckResult
checkCallingConvention(
clang::CallingConv CC) const
clang::TargetInfo::CallingConvCheckResult
checkCallingConvention(
clang::CallingConv CC) constDescription
Determines whether a given calling convention is valid for the target. A calling convention can either be accepted, produce a warning and be substituted with the default calling convention, or (someday) produce an error (such as using thiscall on a non-instance function).
Declared at: clang/lib/Basic/Targets/X86.h:733
Parameters
- clang::CallingConv CC
¶clang::TargetInfo::BuiltinVaListKind
getBuiltinVaListKind() const
clang::TargetInfo::BuiltinVaListKind
getBuiltinVaListKind() constDescription
Returns the kind of __builtin_va_list type that should be used with this target.
Declared at: clang/lib/Basic/Targets/X86.h:721
¶clang::CallingConv getDefaultCallingConv() const
clang::CallingConv getDefaultCallingConv() constDescription
Gets the default calling convention for the given target and declaration context.
Declared at: clang/lib/Basic/Targets/X86.h:751
¶int getEHDataRegisterNumber(
unsigned int RegNo) const
int getEHDataRegisterNumber(
unsigned int RegNo) constDescription
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/X86.h:725
Parameters
- unsigned int RegNo
¶unsigned int getRegisterWidth() const
unsigned int getRegisterWidth() constDescription
Return the "preferred" register width on this target.
Declared at: clang/lib/Basic/Targets/X86.h:760
¶ArrayRef<Builtin::Info> getTargetBuiltins() const
ArrayRef<Builtin::Info> getTargetBuiltins() constDescription
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/X86.h:782
¶unsigned int getUnwindWordWidth() const
unsigned int getUnwindWordWidth() constDeclared at: clang/lib/Basic/Targets/X86.h:758
¶bool hasBitIntType() const
bool hasBitIntType() constDescription
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/X86.h:784
¶bool hasInt128Type() const
bool hasInt128Type() constDescription
Determine whether the __int128 type is supported on this target.
Declared at: clang/lib/Basic/Targets/X86.h:756
¶void setMaxAtomicWidth()
void setMaxAtomicWidth()Description
Set the maximum inline or promote width lock-free atomic operation for the given target.
Declared at: clang/lib/Basic/Targets/X86.h:777
¶bool validateGlobalRegisterVariable(
llvm::StringRef RegName,
unsigned int RegSize,
bool& HasSizeMismatch) const
bool validateGlobalRegisterVariable(
llvm::StringRef RegName,
unsigned int RegSize,
bool& HasSizeMismatch) constDescription
Validate register name used for global register variables. This function returns true if the register passed in RegName can be used for global register variables on this target. In addition, it returns true in HasSizeMismatch if the size of the register doesn't match the variable size passed in RegSize.
Declared at: clang/lib/Basic/Targets/X86.h:762
Parameters
- llvm::StringRef RegName
- unsigned int RegSize
- bool& HasSizeMismatch
