My XXX kernel emulates a floating-point coprocessor for me. Should I enable –with-fp?
{ZW} An emulated FPU is just as good as a real one, as far as the C library is concerned. You only need to say –without-fp if your machine has no way to execute floating-point instructions. People who are interested in squeezing the last drop of performance out of their machine may wish to avoid the trap overhead, but this is far more trouble than it’s worth: you then have to compile *everything* this way, including the compiler’s internal libraries (libgcc.a for GNU C), because the calling conventions change.
