18## Common build system definitions.  Mostly standard
19## commands for building various types of targets, which
20## are used by others to construct the final targets.
21##
22
23# These are variables we use to collect overall lists
24# of things being processed.
25
26# Full paths to all of the documentation
27ALL_DOCS:=
28
29# The short names of all of the targets in the system.
30# For each element of ALL_MODULES, two other variables
31# are defined:
32#   $(ALL_MODULES.$(target)).BUILT
33#   $(ALL_MODULES.$(target)).INSTALLED
34# The BUILT variable contains LOCAL_BUILT_MODULE for that
35# target, and the INSTALLED variable contains the LOCAL_INSTALLED_MODULE.
36# Some targets may have multiple files listed in the BUILT and INSTALLED
37# sub-variables.
38ALL_MODULES:=

41# set of installed targets.

45# LOCAL_MODULE_TAGS.  Each word in this variable maps
46# to a corresponding ALL_MODULE_TAGS.<tagname> variable
47# that contains all of the INSTALLED_MODULEs with that tag.
48ALL_MODULE_TAGS:=
49
50# Similar to ALL_MODULE_TAGS, but contains the short names
51# of all targets for a particular tag.  The top-level variable
52# won't have the list of tags;  ust ALL_MODULE_TAGS to get
53# the list of all known tags.  (This means that this variable
54# will always be empty; it's just here as a placeholder for
55# its sub-variables.)
56ALL_MODULE_NAME_TAGS:=

58# Full paths to all prebuilt files that will be copied
59# (used to make the dependency on acp)
60ALL_PREBUILT:=
61
62# Full path to all files that are made by some tool
63ALL_GENERATED_SOURCES:=
64
65# Full path to all asm, C, C++, lex and yacc generated C files.
66# These all have an order-only dependency on the copied headers
67ALL_C_CPP_ETC_OBJECTS:=

70ALL_ORIGINAL_DYNAMIC_BINARIES:=
