Tue Jul 24 13:09:34 2001 UTC (11 years, 10 months ago) by kreckel
Branch: MAIN
Changes since 1.14: +9 -0 lines
        * prepare for release 1.1.2.

1 kreckel 1.15 2001-07-xx, version 1.1.2
2    
3     Implementation changes
4     ----------------------
5    
6     * Minor cleanups and portability issues.
7     (No need to upgrade if you have been happy so far.)
8    
9    
10 kreckel 1.14 2001-05-31, version 1.1.1
11 kreckel 1.12 =========================
12    
13     Implementation changes
14     ----------------------
15    
16 kreckel 1.13 * Minor cleanups for GCC 3.0 and libstdc++-v3.
17    
18     * Fixes several little bugs and portability issues.
19 kreckel 1.12
20    
21 kreckel 1.11 2000-12-14, version 1.1.0
22 kreckel 1.2 =========================
23    
24 kreckel 1.6 Functional changes
25     ------------------
26    
27     * ISO/IEC 14882 fashion adjustments:
28 haible 1.9 Put everything into namespace cln. All fundamental data types still
29 kreckel 1.6 carry their old names. Other non-macro identifiers are now written as
30     cln::foo instead of cl_foo, except where the cl_ comes from a data type
31     (as in cl_I_to_int()). Headers are installed into a separate
32     directory, #include <cln/foo.h> instead of <cl_foo.h>. Applications
33 haible 1.9 must be manually ported to the new style. We apologize for the
34 kreckel 1.6 inconvenience.
35    
36 kreckel 1.2 Implementation changes
37     ----------------------
38    
39 haible 1.9 * Removed internal copy of mpn subdirectory tree from libgmp-2.0.2.
40     Configuring with --with-gmp now relies on an installed libgmp library
41     version 3 or above. We recommend libgmp-3.1 or newer.
42 kreckel 1.2
43 kreckel 1.3 * Adjusted several break-even points to make better use of a faster libgmp and
44     better match present-day CPUs.
45 kreckel 1.6
46 kreckel 1.7 * Fix several errors for architectures with 64-bit wide words.
47 kreckel 1.11 (Others than Alpha, which worked already.)
48 kreckel 1.7
49 haible 1.9 * Fix compilation errors with current GCC-3.0 snapshots.
50 kreckel 1.3
51 kreckel 1.8 Other changes
52     -------------
53    
54 kreckel 1.10 * Added package tools: script cln-config and autoconf macro AC_PATH_CLN
55 kreckel 1.8 (in file cln.m4).
56    
57 kreckel 1.2
58 kreckel 1.1 2000-01-13, version 1.0.3
59     =========================
60

66    
67     Implementation changes
68     ----------------------
69    
70     * Fix several little configuration errors.
71    
72     * Fix some compilation errors with gcc-2.96 prereleases.
73    
74    
75     1999-09-07, version 1.0.2
76     =========================
77    
78     Functional changes
79     ------------------
80    
81     * New functions
82     `cl_I numerator (const cl_RA&)'
83     `cl_I denominator (const cl_RA&)'.
84     Suggested by Richard Kreckel and Sylvain Pion.
85    
86     * New function `cl_equal_hashcode' for the classes cl_N, cl_R, cl_RA, cl_I,
87     cl_F, cl_SF, cl_FF, cl_DF, cl_LF.
88     Suggested by Richard Kreckel.
89

94     `cl_boolean rootp (const cl_RA&, uintL, cl_RA*)',
95     `cl_boolean rootp (const cl_RA&, const cl_I&, cl_RA*)'
96     was called with an integer argument. Thanks to Richard Kreckel.
97    
98     * Fix a bug in the addition and subtraction of rational numbers which could
99     cause unnormalized rational numbers like 3/1 to be created.
100    
101    
102     1999-06-09, version 1.0.1

134     The file <cl_io.h> now contains only I/O functions for characters and

161    
162     * The function `cl_I xgcd (const cl_I& a, const cl_I& b, cl_I* u, cl_I* v)'
163     now normalizes the resulting u and v to be of minimum absolute value.
164     (Suggested by the LiDIA group.)
165    
166     * The conversion from string to cl_F, cl_R, cl_N now chooses the format of
167     the resulting float depending on the number of significant digits present
168     in the input string.

182    
183     * Fixed a memory leak in the long-float truncate function.
184     (Reported by Keith Briggs.)
185    
186     * Fixed a memory leak in the modular integer exponentiation.
187

190    
191     * Portability fixes for m68k platforms.
192     (Reported and fixed by Roman Hodek.)
193

200     - base + integer + rational
201     - base + integer + rational + float
202     - base + integer + rational + float + real
203     - base + integer + rational + float + real + complex
204     - base + integer + modinteger
205     are now self-contained.
206    
207     * The configuration script can be called with option `--enable-shared',
208     to build CLN as a shared library.
209    
210     * Updated the LiDIA interface.

453     didn't work correctly if both arguments were bignums.
454

468     `type::type (const long)' and `type::type (const unsigned long)'
469     for type=cl_number, type=cl_N, type=cl_RA, type=cl_I that most often
470     caused a core dump.
471    
472     * CLN's word sequences can be chosen to be stored big-endian in memory
473     (like it was up to now) or little-endian (needed for interfacing to GMP).
