DynamicIntrinsicResolver

@dynamicMemberLookup
public struct DynamicIntrinsicResolver

This type provides a dynamic member lookup facility for LLVM intrinsics.

It is not possible to create a DynamicIntrinsicResolver in user code. One is provided by Intrinsic.ID.


                    
                    
                    subscript(dynamicMember:)

Performs a dynamic lookup for the normalized form of an intrinsic selector.

For any LLVM intrinsic selector of the form llvm.foo.bar.baz, the name of the corresponding dynamic member is that name with any dots replaced by underscores.

For example:

llvm.foo.bar.baz -> Intrinsic.ID.llvm_foo_bar_baz
llvm.stacksave -> Intrinsic.ID.llvm_stacksave
llvm.x86.xsave64 -> Intrinsic.ID.llvm_x86_xsave64

Any existing underscores do not need to be replaced, e.g. llvm.va_copy becomes Intrinsic.ID.llvm_va_copy.

For overloaded intrinsics, the non-overloaded prefix excluding the explicit type parameters is used and normalized according to the convention above.

For example:

llvm.sinf64 -> Intrinsic.ID.llvm_sin
llvm.memcpy.p0i8.p0i8.i32 -> Intrinsic.ID.llvm_memcpy
llvm.bswap.v4i32 -> Intrinsic.ID.llvm_bswap

Declaration

Swift

public subscript(dynamicMember selector: String) -> Selector { get }

Parameters


                                selector

The LLVMSwift form of an intrinsic selector.
