I was trying to make a counter which add from 0.0 to 1, I first implement the counter via fadd, then I have trouble to print floating point number.

Platform: Alpine Linux Aarch64 (3.20.2), GNU Binutils (2.42) (Running from a VM on my M2 Mac)

.global _start
.extern printf

.data
    string: .asciz "Hello World! %fn" // Store String
    f: .float 1.132 // Store the float 1.132

.text

_start:

loop:
    ldr x0, =string // Load String into x0
    ldr d1, =f // Load float into d1 (A float reg)

    bl printf // Call printf in glibc
    b exit // Branch to exit label

exit:
    mov x8, #93 // Exit SYSCALL
    mov x0, #0 // Exit code
    svc 0 // Syscall

build.sh

as main.s -o main.o
ld -lc --dynamic-linker /lib/ld-musl-aarch64.so.1 main.o -o main

Output

Hello World! 0.00000
