# 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 options
|
|
#
|
|
# ACTION is currently always "opcodes". It exists to be consistent with the
|
|
# simulator.
|
|
# OPTIONS is comma separated list of options:
|
|
# - 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.
