Graphics on BangleJS2

I was hoping I could add the following to E.compiledC, but even after accounting for the double-escaping, I'm not having success :

float __attribute__((naked)) __aeabi_d2f(double d) {__asm__ volatile(
    "lsrs r0, #30\n\t"
    "lsls r2, r1, #12\n\t"
    "lsrs r2, #9\n\t"
    "asrs r1, #22\n\t"
    "lsls r1, #22\n\t"
    "orrs r0, r1\n\t"
    "orrs r0, r2\n\t"
    "bx lr"
);}

double __attribute__((naked)) __aeabi_f2d(float f) {__asm__ volatile(
    "asrs r1, r0, #3\n\t"
    "movs r2, [#0xf](https://forum.espruino.com/search­/?q=%230xf)\n\t"
    "lsls r2, #27\n\t"
    "orrs r1, r2\n\t"
    "lsls r0, #25\n\t"
    "bx lr"
);}

If you have any luck, please let me know!
