◆ addDefaultFunctionDefinitionAttributes()

void clang::CodeGen::addDefaultFunctionDefinitionAttributes	(	CodeGenModule &	CGM,
		llvm::AttrBuilder &	attrs
	)

Given the language and code-generation options that Clang was configured with, set the default LLVM IR attributes for a function definition.

The attributes set here are mostly global target-configuration and pipeline-configuration options like the target CPU, variant stack rules, whether to optimize for size, and so on. This is useful for frontends (such as Swift) that generally intend to interoperate with C code and rely on Clang's target configuration logic.

As a general rule, this function assumes that meaningful attributes haven't already been added to the builder. It won't intentionally displace any existing attributes, but it also won't check to avoid overwriting them. Callers should generally apply customizations after making this call.

This function assumes that the caller is not defining a function that requires special no-builtin treatment.

Emit va_arg for a platform using the common void* representation, where arguments are simply emitted in an array of slots on the stack.

This version implements the core direct-value passing rules.

Parameters

SlotSize	- The size and alignment of a stack slot. Each argument will be allocated to a multiple of this number of slots, and all the slots will be aligned to this value.
AllowHigherAlign	- The slot alignment is not a cap; an argument type with an alignment greater than the slot size will be emitted on a higher-alignment address, potentially leaving one or more empty slots behind as padding. If this is false, the returned address might be less-aligned than DirectAlign.
ForceRightAdjust	- Default is false. On big-endian platform and if the argument is smaller than a slot, set this flag will force right-adjust the argument in its slot irrespective of the type.

Emit va_arg for a platform using the common void* representation, where arguments are simply emitted in an array of slots on the stack.

Parameters

IsIndirect	- Values of this type are passed indirectly.
ValueInfo	- The size and alignment of this type, generally computed with getContext().getTypeInfoInChars(ValueTy).
SlotSizeAndAlign	- The size and alignment of a stack slot. Each argument will be allocated to a multiple of this number of slots, and all the slots will be aligned to this value.
AllowHigherAlign	- The slot alignment is not a cap; an argument type with an alignment greater than the slot size will be emitted on a higher-alignment address, potentially leaving one or more empty slots behind as padding.

Returns the destructor for a C struct with non-trivially copyable fields, generating it if necessary.

The returned function uses the cdecl calling convention, returns void, and takes a single argument that is a pointer to the address of the struct.

	)

Adds attributes to F according to our CodeGenOpts and LangOpts, as though we had emitted it ourselves.

We remove any attributes on F that conflict with the attributes we add here.

This is useful for adding attrs to bitcode modules that you want to link with but don't control, such as CUDA's libdevice. When linking with such a bitcode library, you might want to set e.g. its functions' "unsafe-fp-math" attribute to match the attr of the functions you're codegen'ing. Otherwise, LLVM will interpret the bitcode module's lack of unsafe-fp-math attrs as tantamount to unsafe-fp-math=false, and then LLVM will propagate unsafe-fp-math=false up to every transitive caller of a function in the bitcode library!

With the exception of fast-math attrs, this will only make the attributes on the function more conservative. But it's unsafe to call this on a function which relies on particular fast-math attributes for correctness. It's up to you to ensure that this is safe.
