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   sizeof(UINT64)

The stack alignment required for ARM

#define DEFAULT_PAGE_ALLOCATION_GRANULARITY   (0x1000)

Page allocation granularity for ARM

#define EFIAPI

#define FUNCTION_ENTRY_POINT

(

FunctionPointer

)

(VOID *)(UINTN)(FunctionPointer)

Return the pointer to the first instruction of a function given a function pointer. On ARM 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 GCC_ASM_EXPORT

(

func__

)

Value:

.global  _CONCATENATE (__USER_LABEL_PREFIX__, func__)    ;\
             .type ASM_PFX(func__), %function

#define GCC_ASM_IMPORT

(

func__

)

.extern _CONCATENATE (__USER_LABEL_PREFIX__, func__)

#define INTERWORK_FUNC

(

func__

)

.type ASM_PFX(func__), %function

ARM EABI defines that the linker should not manipulate call relocations (do bl/blx conversion) unless the target symbol has function type. CodeSourcery 2010.09 started requiring the .type to function properly

#define MAX_2_BITS   0xC0000000

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

#define MAX_ADDRESS   0xFFFFFFFF

Maximum legal ARM address

#define MAX_ALLOC_ADDRESS   MAX_ADDRESS

Maximum usable address at boot time

#define MAX_BIT   0x80000000

A value of native width with the highest bit set.

#define MAX_INTN   ((INTN)0x7FFFFFFF)

Maximum legal ARM INTN and UINTN values.

#define MAX_UINTN   ((UINTN)0xFFFFFFFF)

#define MDE_CPU_ARM

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

#define MIN_INTN   (((INTN)-2147483647) - 1)

Minimum legal ARM INTN value.

#define RUNTIME_PAGE_ALLOCATION_GRANULARITY   (0x1000)

#define UNREACHABLE
