   2 # Generate CGEN opcode files: arch-desc.[ch], arch-opc.[ch],
   3 # arch-asm.c, arch-dis.c, arch-opinst.c, arch-ibld.[ch].
   4 #
   5 # Usage:
   6 # cgen.sh action srcdir cgen cgendir cgenflags arch prefix options
   7 #
   8 # ACTION is currently always "opcodes". It exists to be consistent with the
   9 # simulator.
  10 # OPTIONS is comma separated list of options:
  11 #       - opinst - arch-opinst.c is being made, causes semantic analysis
  12 #
  13 # We store the generated files in the source directory until we decide to
  14 # ship a Scheme interpreter (or other implementation) with gdb/binutils.
  15 # Maybe we never will.
  16
  17 # We want to behave like make, any error forces us to stop.
