BOOLEAN PeCoffLoaderImageFormatSupported

(

IN UINT16

Machine

PeCoffLoaderRelocateImageEx()

RETURN_STATUS PeCoffLoaderRelocateImageEx	(	IN UINT16 *	Reloc,
		IN OUT CHAR8 *	Fixup,
		IN OUT CHAR8 **	FixupData,
		IN UINT64	Adjust
	)

Performs an LoongArch specific relocation fixup and is a no-op on other instruction sets.

Parameters

[in]	Reloc	Pointer to the relocation record.
[in,out]	Fixup	Pointer to the address to fix up.

PeHotRelocateImageEx()

RETURN_STATUS PeHotRelocateImageEx	(	IN UINT16 *	Reloc,
		IN OUT CHAR8 *	Fixup,
		IN OUT CHAR8 **	FixupData,
		IN UINT64	Adjust
	)

Performs an LOONGARCH-based specific re-relocation fixup and is a no-op on other instruction sets. This is used to re-relocated the image into the EFI virtual space for runtime calls.

Parameters

[in]	Reloc	The pointer to the relocation record.
[in,out]	Fixup	The pointer to the address to fix up.
[in,out]	FixupData	The pointer to a buffer to log the fixups.
[in]	Adjust	The offset to adjust the fixup.

Returns
