  22 # Generate CGEN opcode files: arch-desc.[ch], arch-opc.[ch],
  23 # arch-asm.c, arch-dis.c, arch-opinst.c, arch-ibld.[ch].
  24 #
  25 # Usage:
  26 # cgen.sh action srcdir cgen cgendir cgenflags arch prefix options
  27 #
  28 # ACTION is currently always "opcodes". It exists to be consistent with the
  29 # simulator.
  30 # OPTIONS is comma separated list of options:
  31 #       - opinst - arch-opinst.c is being made, causes semantic analysis
  32 #
  33 # We store the generated files in the source directory until we decide to
  34 # ship a Scheme interpreter (or other implementation) with gdb/binutils.
  35 # Maybe we never will.
  36
  37 # We want to behave like make, any error forces us to stop.
