Re: [avr-gcc-list] Assembly + C in AVRGCC 3

[Larry Barello]

Your assembly is in an old dialect (so old I can't recall the name).
The current compiler only recognizes the Binutils (GAS) dialect.

Note: register passing has changed as well as the syntax.  Look at
www.avrfreaks.org in the GCC section for hints and documents on
writing assembly code.
