29# The MC68040 does not implement all MC68881/MC68882 instructions, so use
30# either the gcc floating-point software support (msoft-float libraries), or
31# use the Motorola FPSP floating-point emulator in
32#   rtems/c/src/lib/libcpu/m68k/m68040/fpsp
33# The default is to use the FPSP.
34# To use the msoft-float libraries, uncomment the three lines below.
35# You then should comment the M68KFPSPInstallExceptionHandlers() statement
36# in rtems/c/src/lib/libbsp/m68k/mvme167/startup/bststart.c in bsp_start().
37# Floating-point support will then be limited. See the mvme167 README file
38# for more details.
