+This is the glibc ports repository, an add-on for the GNU C Library (glibc).
+It contains code that is not maintained in the official glibc source tree.
+
+This includes working ports to GNU/Linux on some machine architectures that
+are not maintained in the official glibc source tree.  It also includes
+some code once used by old libc ports now defunct, which has been abandoned
+but may be useful for some future porter to examine.  It may also include
+some optimized functions tailored for specific CPU implementations of an
+architecture, to be selected using --with-cpu.
+
+The ports repository is cooperatively maintained by volunteers on the
+<libc-ports@sourceware.org> mailing list, and housed in the glibc CVS as a
+module called "ports".  See http://www.gnu.org/software/libc/resources.html
+for details on using CVS.  To report a bug in code housed in the ports
+repository, please go to http://sources.redhat.com/bugzilla/ and file a bug
+report under the glibc "ports" component.
+
+An add-on for an individual port can be made from just the sysdeps/
+subdirectories containing the port's code.  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, this must be used by specifying the directory in
+the --enable-add-ons option when running glibc's configure script.

+ * we're interested in is actually the FPU status word - the FPU control
+ * word is something different (which is implementation-defined and only
+ * accessible from supervisor mode.)
+ *
+ * The FPSR looks like this:
+ *
+ *     31-24        23-16          15-8              7-0
+ * | system ID | trap enable | system control | exception flags |

+ * We ignore the system ID bits; for interest's sake they are:
+ *
+ *  0000	"old" FPE
+ *  1000	FPPC hardware
+ *  0001	FPE 400
+ *  1001	FPA hardware
+ *
+ * The trap enable and exception flags are both structured like this:
+ *
+ *     7 - 5     4     3     2     1     0
+ * | reserved | INX | UFL | OFL | DVZ | IVO |
+ *
+ * where a `1' bit in the enable byte means that the trap can occur, and
+ * a `1' bit in the flags byte means the exception has occurred.
+ *
+ * The exceptions are:
+ *
+ *  IVO - invalid operation
+ *  DVZ - divide by zero
+ *  OFL - overflow
+ *  UFL - underflow
+ *  INX - inexact (do not use; implementations differ)
+ *
+ * The system control byte looks like this:
+ *
+ *     7-5      4    3    2    1    0
+ * | reserved | AC | EP | SO | NE | ND |
+ *
+ * where the bits mean
+ *
+ *  ND - no denormalised numbers (force them all to zero)
+ *  NE - enable NaN exceptions
+ *  SO - synchronous operation
+ *  EP - use expanded packed-decimal format
+ *  AC - use alternate definition for C flag on compare operations

+	 Suppose there is a byte with all zeros.  Any carry bits
+	 propagating from its left will fall into the hole at its
+	 least significant bit and stop.  Since there will be no
+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.	If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-31 is set, there will be a carry
+	 into bit 32 (=carry flag), so all of the hole bits will
+	 be changed.
+
+	 3) But wait!  Aren't we looking for C, not zero?
+	 Good point.  So what we do is XOR LONGWORD with a longword,
+	 each of whose bytes is C.  This turns each byte that is C
+	 into a zero.  */

+	 Suppose there is a byte with all zeros.  Any carry bits
+	 propagating from its left will fall into the hole at its
+	 least significant bit and stop.  Since there will be no
+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.	If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-31 is set, there will be a carry
+	 into bit 32 (=carry flag), so all of the hole bits will
+	 be changed.
+
+	 3) But wait!  Aren't we looking for C, not zero?
+	 Good point.  So what we do is XOR LONGWORD with a longword,
+	 each of whose bytes is C.  This turns each byte that is C
+	 into a zero.  */

+	 1) Is this safe?  Will it catch all the zero bytes?
+	 Suppose there is a byte with all zeros.  Any carry bits
+	 propagating from its left will fall into the hole at its
+	 least significant bit and stop.  Since there will be no
+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.	If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-31 is set, there will be a carry
+	 into bit 32 (=carry flag), so all of the hole bits will
+	 be changed.
+
+	 3) But wait!  Aren't we looking for C, not zero?
+	 Good point.  So what we do is XOR LONGWORD with a longword,
+	 each of whose bytes is C.  This turns each byte that is C
+	 into a zero.  */

+; 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.)

+# Before version 2.6, linux had separate 32-bit and 64-bit MIPS ports,
+# each with its own set of headers.  The ports were merged for 2.6 and
+# this merged port defines the syscalls in a slightly different way.
+# There are therefore three sets of headers that we need to consider:
+#
+#    (1) Headers from the separate 32-bit MIPS port.  They just define
+#	 a single list of __NR macros.
+#
+#    (2) Headers from the separate 64-bit MIPS port.  They unconditionally
+#	 define syscalls for all three ABIs, with o32 syscalls prefixed
+#	 by __NR_O32, n32 syscalls prefixed by __NR_N32 and n64 syscalls
+#	 prefixed by plain __NR.
+#
+#    (3) Headers from the combined port.  They use the _MIPS_SIM macro to
+#	 define the right set of syscalls for the current ABI.  The syscalls
+#	 themselves have no special ABI prefix, but the headers also define:
+#
+#	    __NR_O32_Linux{,_syscalls}
+#	    __NR_N32_Linux{,_syscalls}
+#	    __NR_64_Linux{,_syscalls}
+#
+# In case (1) we just want a simple list of SYS_* macros.  In cases (2)
+# and (3) we want a file that will work for all three ABIs, regardless
+# of which ABI we are currently using.  We also want the file to work
+# if the user later moves from (2) to (3).  Thus the file we create
+# for (2) and (3) has the form:
+#
+#    #if _MIPS_SIM == _ABIN32
+#    # ifdef __NR_N32_open
+#    #  define SYS_n32syscall1 __NR_N32_n32syscall1
+#    #  ...
+#    # else
+#    #  define SYS_n32syscall1 __NR_n32syscall1
+#    #  ...
