  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 \
  27 #         arch-file opc-file options [extrafiles]
  28 #
  29 # ACTION is currently always "opcodes". It exists to be consistent with the
  30 # simulator.
  31 # ARCH is the name of the architecture.
  32 # It is substituted into @arch@ and @ARCH@ in the generated files.
  33 # PREFIX is both the generated file prefix and is substituted into
  34 # @prefix@ in the generated files.
  35 # ARCH-FILE is the name of the .cpu file (including path).
  36 # OPC-FILE is the name of the .opc file (including path).
  37 # OPTIONS is comma separated list of options (???).
  38 # EXTRAFILES is a space separated list (1 arg still) of extra files to build:
  39 #       - opinst - arch-opinst.c is being made, causes semantic analysis
  40 #
  41 # We store the generated files in the source directory until we decide to
  42 # ship a Scheme interpreter (or other implementation) with gdb/binutils.
  43 # Maybe we never will.
  44
  45 # We want to behave like make, any error forces us to stop.
