Subject: [Bug target/21079] avr-gcc lacks support for builtin ffs function
Date: Sun, 17 Apr 2005 22:45:00 -0000	[thread overview]

ffs is a POSIX function which almost all libc provides.
So if there is no fall back function, there is nothing which GCC can do.

Does avr have instructions which could be used to implement this if so it should implement ffssi/ffsdi 
and such.
