8e10b365 21# The makefile built from this file lives in the language subdirectory.
de18aff3 22# Its purpose is to provide support for:
8e10b365
DE
23#
24# 1) recursion where necessary, and only then (building .o's), and
25# 2) building and debugging cc1 from the language subdirectory, and
26# 3) nothing else.
27#
28# The parent makefile handles all other chores, with help from the
29# language makefile fragment, of course.
30#
31# The targets for external use are:
32# all, TAGS, ???mostlyclean, ???clean.
