# 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.
