# The makefile built from this file lives in the language subdirectory.
|
|||
|
# Its purpose is to provide support for:
|
|||
|
#
|
|||
|
# 1) recursion where necessary, and only then (building .o's), and
|
|||
|
# 2) building and debugging cc1 from the language subdirectory, and
|
|||
|
# 3) nothing else.
|
|||
|
#
|
|||
|
# The parent makefile handles all other chores, with help from the
|
|||
|
# language makefile fragment, of course.
|
|||
|
#
|
|||
|
# The targets for external use are:
|
|||
|
# all, TAGS, ???mostlyclean, ???clean.
|
|||
|
|
|||
|
# Suppress smart makes who think they know how to automake Yacc files
