Raw Blame History

#
# Version 0.7.10, 2012-02-13
#
2012-02-08 Thomas Pircher <tehpeh@gmx.net>
* crc_symtable.py:
Bad-looking C code generated; make sure the bit-by-bit(fast) code does not
contain two instructions on one line. Thanks to "intgr" for the fix.
* crc_symtable.py:
Some small code clean-up: use set() when appropriate.
2011-12-19 Thomas Pircher <tehpeh@gmx.net>
* crc_models.py:
* doc/pycrc.xml:
Added the models crc-12-3gpp, crc-16-genibus, crc-32-bzip2 and crc-64-xz.
Taken from Greg Cook's Catalogue of parametrised CRC algorithms:
http://regregex.bbcmicro.net/crc-catalogue.htm
2011-12-14 Thomas Pircher <tehpeh@gmx.net>
* doc/pycrc.xml:
Fixed a mistake in the man page that still used the old model name
crc-32mpeg instead of crc-32-mpeg. Thanks to Marek Erban.
#
# Version 0.7.9, 2011-12-08
#
2011-12-08 Thomas Pircher <tehpeh@gmx.net>
* crc_symtable.py:
Fixed a bug in the generated C89 code that included stdint.h.
Thanks to Frank (ftheile).
Closes issue 3454356.
2011-11-08 Thomas Pircher <tehpeh@gmx.net>
* crc_symtable.py:
Fixed a bug in the generated C89 code when using a 64 bit CRC.
* pycrc.py:
Using the --verbose option made pycrc quit without error message.
#
# Version 0.7.8, 2011-07-10
#
2011-07-10 Thomas Pircher <tehpeh@gmx.net>
* crc_symtable.py:
When generating C code for the C89 or ANSI standard, don't include <stdint.h>.
This closes issue 3338930
* crc_symtable.py:
If no output file name is given while generating a C file, then pycrc will
#include a hypothetical pycrc.h file instead of a stdout.h file.
Also, added a comment on that line to make debugging easier.
Closes issue 3325109.
* crc_symtable.py:
Removed unused variable "this_option_optind" in the generated option parser.
#
# Version 0.7.7, 2011-02-11
#

for Python3 compatibility.
#
# Version 0.7.5, 2010-03-28
#
2010-03-27 Thomas Pircher <tehpeh@gmx.net>

C/C++ code can now be generated for the table-driven algorithm with widths
that are not byte-ligned or less than 8.
W A R N I N G: introduced new variable crc_shift, member of the crc_cfg_t
structure, that must be initialised manually when the width
was undefined during C/C++ code generation.
2010-03-27 Thomas Pircher <tehpeh@gmx.net>
* crc_opt.py, crc_algorithms.py:
Python implementation of the table-driven algorithm can handle widths less
than 8.
