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.

Determine whether the _BitInt type is supported on this target.

This limitation is put into place for ABI reasons.

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.

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.

Reimplemented from clang::TargetInfo.

Definition at line 231 of file AArch64.cpp.

◆ validatePointerAuthKey()

bool AArch64TargetInfo::validatePointerAuthKey ( const llvm::APSInt & value ) const

overridevirtual

Determine whether the given pointer-authentication key is valid.

The value has been coerced to type 'int'.

◆ validateTarget()

bool AArch64TargetInfo::validateTarget ( DiagnosticsEngine & Diags ) const

overridevirtual

Check the target is valid after it is fully initialized.
