Macro Definition Documentation

#define __USER_LABEL_PREFIX__

#define ASM_GLOBAL   .globl

For GNU assembly code, .global or .globl can declare global symbols. Define this macro to unify the usage.

#define CPU_STACK_ALIGNMENT   16

The stack alignment required for x64

#define DEFAULT_PAGE_ALLOCATION_GRANULARITY   (0x1000)

Page allocation granularity for x64

#define EFIAPI   __cdecl

Microsoft* compiler specific method for EFIAPI calling convention.

#define FUNCTION_ENTRY_POINT

(

FunctionPointer

)

(VOID *)(UINTN)(FunctionPointer)

Return the pointer to the first instruction of a function given a function pointer. On x64 CPU architectures, these two pointer values are the same, so the implementation of this macro is very simple.

Parameters

FunctionPointer

A pointer to a function.

Returns

The pointer to the first instruction of a function given a function pointer.

#define MAX_2_BITS   0xC000000000000000ULL

A value of native width with the two highest bits set.

#define MAX_ADDRESS   0xFFFFFFFFFFFFFFFFULL

Maximum legal x64 address

#define MAX_ALLOC_ADDRESS   MAX_ADDRESS

Maximum usable address at boot time

#define MAX_BIT   0x8000000000000000ULL

A value of native width with the highest bit set.

#define MAX_INTN   ((INTN)0x7FFFFFFFFFFFFFFFULL)

Maximum legal x64 INTN and UINTN values.

#define MAX_UINTN   ((UINTN)0xFFFFFFFFFFFFFFFFULL)

#define MDE_CPU_X64

Define the processor type so other code can make processor based choices

#define MIN_INTN   (((INTN)-9223372036854775807LL) - 1)

Minimum legal x64 INTN value.

#define RUNTIME_PAGE_ALLOCATION_GRANULARITY   (0x1000)

Typedef Documentation

2-byte signed value

typedef __int32 INT32

4-byte signed value

typedef __int64 INT64

8-byte signed value

typedef signed char INT8

1-byte signed value

typedef INT64 INTN
