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