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

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