# Generate CGEN opcode files: arch-desc.[ch], arch-opc.[ch],

# arch-asm.c, arch-dis.c, arch-opinst.c, arch-ibld.[ch].

#

# Usage:

# cgen.sh action srcdir cgen cgendir cgenflags arch prefix \

#         arch-file opc-file options [extrafiles]

#

# ACTION is currently always "opcodes". It exists to be consistent with the

# simulator.

# ARCH is the name of the architecture.

# It is substituted into @arch@ and @ARCH@ in the generated files.

# PREFIX is both the generated file prefix and is substituted into

# @prefix@ in the generated files.

# ARCH-FILE is the name of the .cpu file (including path).

# OPC-FILE is the name of the .opc file (including path).

# OPTIONS is comma separated list of options (???).

# EXTRAFILES is a space separated list (1 arg still) of extra files to build:

#       - opinst - arch-opinst.c is being made, causes semantic analysis

#

# We store the generated files in the source directory until we decide to

# ship a Scheme interpreter (or other implementation) with gdb/binutils.

# Maybe we never will.

# We want to behave like make, any error forces us to stop.
