1997-06-21 02:48 Ulrich Drepper <drepper@cygnus.com> * config.h.in: Add DO_STATIC_NSS. * config.make.in: Add build-static-nss. * elf/eval.c: Use __getdelim instead of __getline. * locale/programs/locale.c: Correct comment. * manual/libc.texinfo: Update copyright and date. Remove A4 option. * sysdeps/libm-ieee754/k_standard.c: Always return HUGE_VAL for gamma overflow. * sysdeps/libm-ieee754/w_gamma.c: Handle SVID and ISO C behaviour. * sysdeps/libm-ieee754/w_gammaf.c: Likewise. * sysdeps/libm-ieee754/w_gammalp.c: Likewise. * po/ko.po: Update. 1997-06-13 10:06 Richard Henderson <rth@tamu.edu> The Great Bit File Move: * configure.in (AC_INIT): Look in include/ for features.h. (sysnames): Add include as the final search directory. (AC_OUTPUT): Create a bits directory in the build directory. * Makeconfig (CPPFLAGS): Look in include/ for libc-symbols.h. * Makefile: Make sure the target directory exists when installing <gnu/stubs.h> and <gnu/lib-names.h>. * csu/Makefile: Use $(compile.S) and $(compile.c) instead of invoking $(CC) directly, as the former have the full include path. * ansidecl.h: Removed. * aliases.h:

/* An improved random number generation package. In addition to the standard
|
||
rand()/srand() like interface, this package also has a special state info
|
||
interface. The initstate() routine is called with a seed, an array of
|
||
bytes, and a count of how many bytes are being passed in; this array is
|
||
then initialized to contain information for random number generation with
|
||
that much state information. Good sizes for the amount of state
|
||
information are 32, 64, 128, and 256 bytes. The state can be switched by
|
||
calling the setstate() function with the same array as was initialized
|
||
with initstate(). By default, the package runs with 128 bytes of state
|
||
information and generates far better random numbers than a linear
|
||
congruential generator. If the amount of state information is less than
|
||
32 bytes, a simple linear congruential R.N.G. is used. Internally, the
|
||
state information is treated as an array of longs; the zeroth element of
|
||
the array is the type of R.N.G. being used (small integer); the remainder
|
||
of the array is the state information for the R.N.G. Thus, 32 bytes of
|
||
state information will give 7 longs worth of state information, which will
|
||
allow a degree seven polynomial. (Note: The zeroth word of state
|
||
information also has some other information stored in it; see setstate
|
||
for details). The random number generation technique is a linear feedback
|
||
shift register approach, employing trinomials (since there are fewer terms
|
||
to sum up that way). In this approach, the least significant bit of all
|
||
the numbers in the state table will act as a linear feedback shift register,
|
||
and will have period 2^deg - 1 (where deg is the degree of the polynomial
|
||
being used, assuming that the polynomial is irreducible and primitive).
|
||
The higher order bits will have longer periods, since their values are
|
||
also influenced by pseudo-random carries out of the lower bits. The
|
||
total period of the generator is approximately deg*(2**deg - 1); thus
|
||
doubling the amount of state information has a vast influence on the
|
||
period of the generator. Note: The deg*(2**deg - 1) is an approximation
|
||
only good for large deg, when the period of the shift register is the
|
||
dominant factor. With deg equal to seven, the period is actually much
|
||
longer than the 7*(2**7 - 1) predicted by this formula. */

the polynomial (actually a trinomial) that the R.N.G. is based on, and
|
||
separation between the two lower order coefficients of the trinomial. */
