21 # The makefile built from this file lives in the language subdirectory.
22 # Its purpose is to provide support for:
24 # 1) recursion where necessary, and only then (building .o's), and
25 # 2) building and debugging cc1 from the language subdirectory, and
28 # The parent makefile handles all other chores, with help from the
29 # language makefile fragment, of course.
31 # The targets for external use are:
32 # all, TAGS, ???mostlyclean, ???clean.
34 # Suppress smart makes who think they know how to automake Yacc files
37 # Variables that exist for you to override.
38 # See below for how to change them for certain systems.
42 # Various ways of specifying flags for compilations:
43 # CFLAGS is for the user to override to, e.g., do a bootstrap with -O2.
44 # BOOT_CFLAGS is the value of CFLAGS to pass
45 # to the stage2 and stage3 compilations
46 # XCFLAGS is used for most compilations but not when using the GCC just built.
49 BOOT_CFLAGS = -O $(CFLAGS)
50 # These exists to be overridden by the x-* and t-* files, respectively.
68 # Define this as & to perform parallel make on a Sequent.
69 # Note that this has some bugs, and it seems currently necessary
70 # to compile all the gen* files first by hand to avoid erroneous results.
73 # This is used in the definition of SUBDIR_USE_ALLOCA.
74 # ??? Perhaps it would be better if it just looked for *gcc*.
77 # This is used instead of ALL_CFLAGS when compiling with GCC_FOR_TARGET.
78 # It omits XCFLAGS, and specifies -B./.
79 # It also specifies -B$(tooldir)/ to find as and ld for a cross compiler.
