Daniel Marjamäki ca7ec25b92 Merge pull request #708 from siemens/preprocessor-directives-for-addons-v2
Add preprocessor directives dump and Y2038 addon
2016-01-16 12:28:14 +01:00
Matthias Krüger 7b1710a44f redundantAssignment: change from severity 'performance' to 'style' since avoiding unneccessary stores is a basic optimization done by compilers. 2016-01-15 22:01:40 +01:00
Albert ARIBAUD (3ADEV) 38e70dfb74 Preprocessor directives for addons
This patch augments the XML dumps with a 'directivelist'
subnode which lists all raw preprocessor directives met
while reading the source code in each configuration.

Also, the addons/cppcheckdata.py file has been extended
to give easy access to the list of directives and to
provide Python support for the --template (or short -t)
option.

Finally, an new addon, addons/y2038/y2038.py, is created
to detect when a glibc symbol might be Y2038-sensitive,
based on whether and how _TIME_BITS and _USE_TIME_BITS64
are defined when meeting the symbol.
