I succesfully configured and build gcc 2.3.1 as cross compiler, running on
a sun4, producing code for a sun3.  I also build the compiler to run on a
sun3 and to produce code for a sun3.
However, a program compiled with the cross compiler runs almost twice as slow
as the program compiled with the non-cross compiler (on a sun3)
Both compilers were told to optimize with the -O2 flag.
Both compilers produced hardware floating point instructions.
Is it possible that -O2 does less optimizations on the cross compiler than on
the non-cross compiler ?
