		bool	AttrOnCallSite,
		bool	IsThunk
	)

Get the LLVM attributes and calling convention to use for a particular function type.

Construct the IR attribute list of a function or call.

Parameters

Name	- The function name.
Info	- The function type information.
CalleeInfo	- The callee information these attributes are being constructed for. If valid, the attributes applied to this decl may contribute to the function attributes and calling convention.
Attrs	[out] - On return, the attribute list to use.
CallingConv	[out] - On return, the LLVM calling convention to use.

When adding an attribute, please consider where it should be handled:

getDefaultFunctionAttributes is for attributes that are essentially part of the global target configuration (but perhaps can be overridden on a per-function basis). Adding attributes there will cause them to also be set in frontends that build on Clang's target-configuration logic, as well as for code defined in library modules such as CUDA's libdevice.
ConstructAttributeList builds on top of getDefaultFunctionAttributes and adds declaration-specific, convention-specific, and frontend-specific logic. The last is of particular importance: attributes that restrict how the frontend generates code must be added here rather than getDefaultFunctionAttributes.

◆ GenKernelArgMetadata()

void CodeGenModule::GenKernelArgMetadata	(	llvm::Function *	FN,

OpenCL v1.2 s5.6.4.6 allows the compiler to store kernel argument information in the program executable.

The argument information stored includes the argument name, its type, the address and access qualifiers used. This helper can be used to generate metadata for source code kernel function as well as generated implicitly kernels. If a kernel is generated implicitly null value has to be passed to the last two parameters, otherwise all parameters must have valid non-null values.

Parameters

FN	is a pointer to IR function being generated.
FD	is a pointer to function declaration if any.
CGF	is a pointer to CodeGenFunction that generates this function.
