__attribute__((naked)) is this option available?

mike morgen

Hi
I want to use this __attribute__((naked)) for one of my functions in keil, but it generates a warning that says

main.c(6846): warning: #1207-D: unknown attribute "naked"

This is my function prototype

__attribute__((naked)) void myTestFunction(void)
{
}

what's going on? what should I do to enable the naked!?

    for __CC_ARM, no it is not supported. use

    __asm void myTestFunction(void)

    make sure you look up what __attribute__((naked)) actually means as it appears as if you are creating a "C" function and the naked attribute only has meaning for routines consisting entirely of asm instructions.

    ARMCLANG also supports __attribute__((naked))
