annotate tests/cptest.c @ 4:6b1594fb668f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Improve performance of jtag.c and test it with Python scripts. - cp_tditdo.py send bits to TDI and hope it will feed back from TDO. - Expand loops in jtag.c to improve performance.
