There are certainly code generation bugs in gcc, but not many.  There
are no known problems that are specific to that processor.

The most common cause of a program which fails at -O2 with newer gcc is
invalid aliasing in the program.  Try using the -fno-strict-aliasing
option.

The second most common cause is invalid reliance on the behaviour of
signed overflow.  Try using the -fno-strict-overflow option.
