| (...) Total .text section is 5832 bytes, .rodata is 4 bytes, and .bss is 8 bytes. This is for all for all of the FP emulation routines, only those actually used will be linked in. This is only the helper routines, not anything from the math library. (...) (25 years ago, 3-May-99, to lugnet.robotics)
