01. ldmea指令

程序示例

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:push {lr}adr r4, .L1ldmea r4, {r1, r2, r3}ldr r0, =.LC1bl printfmov r0, #0pop {pc}.L0:.word 0x1111.word 0x2222.word 0x3333.L1:.word 0x0

02. ldmed指令

程序示例

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:push {lr}adr r4, .L0ldmed r4, {r1-r3}ldr r0, =.LC1bl printfmov r0, #0pop {pc}.L0:.word 0x1111.word 0x2222.word 0x3333.L1:.word 0x0

03. ldmfa指令

程序示例

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:push {lr}adr r4, .L1ldmfa r4, {r1-r3}ldr r0, =.LC1bl printfmov r0, #0pop {pc}.L0:.word 0x1111.word 0x2222.word 0x3333.L1:.word 0x0

04. ldmfd指令

程序示例

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:push {lr}adr r4, .L0ldmfd r4, {r1-r3}ldr r0, =.LC1bl printfmov r0, #0pop {pc}.L0:.word 0x1111.word 0x2222.word 0x3333.L1:.word 0x0

05. stmea指令

程序示例:

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:stmfd sp!, {lr}mov fp, spsub sp, sp, #12mov r1, #1mov r2, #2mov r3, #3stmea sp, {r1, r2, r3}ldmfd sp, {r1, r2, r3}ldr r0, =.LC1bl printfmov r0, #0mov sp, fpldmfd sp!, {lr}

06. stmed指令

程序示例:

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:stmfd sp!, {lr}mov fp, spsub sp, sp, #4mov r1, #1mov r2, #2mov r3, #3stmed sp!, {r1, r2, r3}ldmed sp!, {r1, r2, r3}ldr r0, =.LC1bl printfmov r0, #0mov sp, fpldmfd sp!, {lr}

07. stmfa指令

程序示例:

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:stmfd sp!, {lr}mov fp, spsub sp, sp, #16mov r1, #1mov r2, #2mov r3, #3stmfa sp, {r1, r2, r3}ldmed sp, {r1, r2, r3}ldr r0, =.LC1bl printfmov r0, #0mov sp, fpldmfd sp!, {lr}

08. stmfd指令

程序示例:

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n".section .text.align 2.global main main:stmfd sp!, {lr}mov fp, spmov r1, #1mov r2, #2mov r3, #3stmfd sp, {r1, r2, r3}ldmea sp, {r1, r2, r3}ldr r0, =.LC1bl printfmov r0, #0mov sp, fpldmfd sp!, {lr}

09. swp指令

程序示例:

.section .rodata.align 2 .LC0:.string "hello world\n" .LC1:.string "var = %p %p %p\n" .LC2:.string "val = %d\n".section .text.align 2.global main main:stmfd sp!, {lr}mov fp, spsub sp, sp, #4mov r0, #10str r0, [sp]mov r2, #20swp r1, r2, [sp]ldr r0, =.LC2bl printfldr r1, [sp]ldr r0, =.LC2bl printfmov r0, #0mov sp, fpldmfd sp!, {lr}
