The inline assembly used in C/C++ when program need to access the specific allocated register or memory for the C/C++ variable. You may want to use the -fno- gnu-keywords flag instead, which has the same effect. Although avr-libc is primarily targeted to support programming AVR microcontrollers using the C (and C++) language, there's limited support for direct assembler usage as well. One thing I have found is that by programming in Assembly, I have developed a better sense of the AVRs power. noexcept specifier (C++11). To declare inline assembly functions, we use the keyword asm. It was developed in the year 1996 by ATMEL Corporation.

Inline asm statements containing assembler instruction only are also known as basic inline assembly, while statements containing optional parts are called extended inline assembly. As far as the hardware is concerned, they are all the same, with the sole exception of register 0, which is hardwired to the value 0. The syntax of inline assembly looks completely different from C/C++. avr-libc and assembler programs. I needed one function to be as optimal as possible. Die Adresse soll in addr stehen.
