That's also what gcc does on AMD64:

[/tmp:171587] cat xxx.c
double f(double x)
{
  return x+1234.0;
}
[/tmp:171588] gcc -O -S xxx.c
[/tmp:171589] cat xxx.s
        .file   "xxx.c"
        .text
        .globl  f
        .type   f, @function
f:
.LFB0:
        .cfi_startproc
        addsd   .LC0(%rip), %xmm0
        ret
        .cfi_endproc
.LFE0:
        .size   f, .-f
        .section        .rodata.cst8,"aM",@progbits,8
        .align 8
.LC0:
        .long   0
        .long   1083394048
        .ident  "GCC: (Debian 12.2.0-14) 12.2.0"
        .section        .note.GNU-stack,"",@progbits
