Is it possible to declare "naked" functions with armcc (KEIL)?

With GCC I use this kind of functions:
__attribute__((naked))
void tb_flush(char* val1, int val2) {
asm volatile (".thumb_func\n bx lr\n");
}
This allows me to make PC jump to the tb_flush function and leave very quicly without saving/restoring the stack/regs. It is also different from declaring the function as inline, because I need the PC to change to this address (trap with OCD PC breakpoints or monitoring in my verilog testbench)
Does someone know how to do the same thing with armcc ?
Regards,
Sylvain
