96 # The logic here is partly dictated by the desire to keep the lib?77
97 # subdirs for compatibility with the Netlib version and because libU77
98 # has a different copyright; then the libe77 bit (EXTERNALly-callable
99 # versions) is funny. Given that, as well as keeping things as simple
100 # as possible we want (at least) the following:
101 # * Allow make to be run at the top level (all-target-libf2c), at this
102 # level, or the subdirs of this level. In the latter case we only
103 # compile, rather than updating libg2c.a;
104 # * A robust set of dependencies, so that we rebuild (as little as
105 # possible) if a configuration file, g2c.h or any lib?77/*.c file
107 # * Avoid unnecessary running of ar and ranlib;
108 # * Expose parallelism where reasonable, but not as a priority.
110 # The intended top-level target here does a non-multilib build (via
111 # the dependency) and then (perhaps) builds multilibs.

116 # `all-unilib' is the overall target in the absence of multilibs,
117 # meant to be invoked via multi-do for multilibs.
119 # Its dependencies can be satisfied in parallel. The [fiu]77 targets
120 # update stamp files (see the subdir makefiles) which the $(LIBG2C)
121 # target checks in the sub make to decide whether to run ar/ranlib.
122 # (Probably only one stamp file is really needed.) The stamp files
123 # s-lib[fiu]77 are intentionally not targets, since we're only meant
124 # to come in at the level of this target. The [fiu]77 targets always
125 # invoke sub makes to check dependencies in the subdirs, else we'd
126 # have to maintain them at this level; we live with the overhead of
127 # some recursive makes which may do nothing.
