+This directory is an add-on for the GNU C Library (glibc).
+It provides additional ports to machines and/or operating systems that are
+not maintained in the official glibc source tree.
+
+The scripts in the top level of this directory provide the infrastructure
+necessary for a glibc add-on.  You can make a new add-on containing one or
+more ports by copying configure, configure.in, and Makeconfig into your own
+add-on directory, which you can give any name (it doesn't have to be
+`ports').  You may want to include a README and Banner of your own talking
+about your port's code in particular, rather than the generic ones here.
+
+The real source code for any ports is found in the sysdeps/ subdirectories.
+These should be exactly what would go into the main libc source tree if you
+were to incorporate it directly.  The only exceptions are the files
+sysdeps/*/preconfigure and sysdeps/*/preconfigure.in; these are fragments
+used by this add-on's configure fragment.  The purpose of these is to set
+$base_machine et al when the main libc configure's defaults are not right
+for some machine.  Everything else can and should be done from a normal
+sysdeps/.../configure fragment that is used only when the configuration
+selects that sysdeps subdirectory.  Each port that requires some special
+treatment before the sysdeps directory list is calculated, should add a
+sysdeps/CPU/preconfigure file; this can either be written by hand or
+generated by Autoconf from sysdeps/CPU/preconfigure.in, and follow the
+rules for glibc add-on configure fragments.  No preconfigure file should do
+anything on an unrelated configuration, so that disparate ports can be put
+into a single add-on without interfering with each other.
+
+Like all glibc add-ons, the only way to use this is to place this directory
+(just a symlink won't do) inside the top-level glibc source directory.
+Then include the name of this directory (e.g. `ports') when you specify
+`--enable-add-ons=...' to glibc's configure (or use just --enable-add-ons
+to have it try every add-on directory sitting in your source tree).
+
+If you find problems with the top-level scripts in this add-on, please go
+to http://sources.redhat.com/bugzilla/ and file a report for the glibc
+under the "admin" component.

+; Common overhead is about 11 cycles/invocation.
+
+; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention.)
+
+; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
+
+; To enhance speed:
+; 1. Unroll main loop 4-8 times.
+; 2. Schedule code to avoid WB contention.  It might be tempting to move the
+;    ld instruction in the loops down to save 2 cycles (less WB contention),
+;    but that looses because the ultimate value will be read from outside
+;    the allocated space.  But if we handle the ultimate multiplication in
+;    the tail, we can do this.
+; 3. Make the multiplication with less instructions.  I think the code for
+;    (S2_LIMB >= 0x10000) is not minimal.
+; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
+; less cycles/limb; the (S2_LIMB < 0x10000) case would run in 11

+; Common overhead is about 11 cycles/invocation.
+
+; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention.)
+
+; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb.  (The
+; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
+
+; To enhance speed:
+; 1. Unroll main loop 4-8 times.
+; 2. Schedule code to avoid WB contention.  It might be tempting to move the
+;    ld instruction in the loops down to save 2 cycles (less WB contention),
+;    but that looses because the ultimate value will be read from outside
+;    the allocated space.  But if we handle the ultimate multiplication in
+;    the tail, we can do this.
+; 3. Make the multiplication with less instructions.  I think the code for
+;    (S2_LIMB >= 0x10000) is not minimal.
+; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
+; less cycles/limb; the (S2_LIMB < 0x10000) case would run in 11
+; cycles/limb.  (Assuming infinite unrolling.)
