1418 # Preprocessing rules

1420 # The PP_TARGETS variable contains a list of all preprocessing target
1421 # categories. Each category has associated variables listing input files, the
1422 # output directory, extra preprocessor flags, and so on. For example:
1423 #
1424 #   FOO := input-file
1425 #   FOO_PATH := target-directory
1426 #   FOO_FLAGS := -Dsome_flag
1427 #   PP_TARGETS += FOO
1428 #
1429 # If PP_TARGETS lists a category name <C> (like FOO, above), then we consult the
1430 # following make variables to see what to do:
1431 #
1432 # - <C> lists input files to be preprocessed with mozbuild.action.preprocessor.
1433 #   We search VPATH for the names given here. If an input file name ends in
1434 #   '.in', that suffix is omitted from the output file name.
1435 #
1436 # - <C>_PATH names the directory in which to place the preprocessed output
1437 #   files. We create this directory if it does not already exist. Setting
1438 #   this variable is optional; if unset, we install the files in $(CURDIR).
1439 #
1440 # - <C>_FLAGS lists flags to pass to mozbuild.action.preprocessor, in addition
1441 #   to the usual bunch. Setting this variable is optional.
1442 #
1443 # - <C>_TARGET names the 'make' target that should depend on creating the output
1444 #   files. Setting this variable is optional; if unset, we preprocess the
1445 #   files for the 'libs' target.
1446 #
1447 # - <C>_KEEP_PATH may be set to 1 to indicate the paths given in <C> are to be
1448 #   kept under <C>_PATH. That is, if <C> is bar/baz/qux.h.in and <C>_PATH is
1449 #   $(DIST)/include, the preprocessed file would be $(DIST)/include/bar/baz/qux.h
