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.
