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.
