trying to remane the variable

trying to use asm constraints

a terribly awkward workaround

so my question is...

Looking at the object symbol table, the only label for global_var is a C++-like mangled name. No my_var label seems to be generated.

__attribute__((always_inline)) pass_param(unsigned char data)
{
 asm volatile ("cmp %0,%0\n"::"r"(data));
} 

Looking at the object symbol table, the only label for global_var is a C++-like mangled name.
However hard I tried this renaming trick, I could not bring the compiler to generate a my_var label.

__attribute__((always_inline)) give_me_my_friggin_variable(char data)
{
 asm volatile ("cmp %0,%0\n"::"r"(data));
} 
ISR (TIMER2_COMPA_Vect, ISR_NAKED) {
 <some prologue to save SREG and all needed registers>
 //...
 give_me_my_friggin_variable(Driver.ISR_param);
 // continue assembly code with r24 properly initialized
}
