3# Makefile snippet to build a crunchgen(1)ed binary from the provided lists
4#
5# Required variables:
6#         NETBSDSRCDIR        top level of src tree (set by <bsd.own.mk>)
7#         CRUNCHBIN name of crunchgen(1)ed binary
8#         LISTS               list file(s) to use
9#
10# Optional variables:
11#         SMALLPROG if != 0, add SMALLPROG=1 to CRUNCHENV.  [default: 1]
12#         SMALLPROG_INET6     if != 0 and SMALLPROG != 0, and ${USE_INET6} != "no",
13#                             add SMALLPROG_INET6=1 to CRUNCHENV.  [default: 0]
14#         CRUNCHENV environment to pass to crunchgen(1) and when building
15#                             the crunched program with make(1) (as command line
16#                             variables, to override any user provided environment
17#                             or make(1) cmdline vars).
18#         CRUNCHGEN_FLAGS     extra options to crunchgen(1)
19#         DESTDIR             destination directory
20#         PARSELISTENV        environment variables to set for parselist.awk
21#
22# Variables modified by this:
23#         CRUNCHENV may get SMALLPROG=1 or SMALLPROG_INET6=1 added
