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.

Miika-Petteri Matikainen acd8a092f8 Make syntaxError suppressable (fixes #5917 and #7076)

InternalErrors which were thrown and catched during the checking,
and normal suppression rules were not applied for those.

We fix this by calling the normal reportErr() function that does
suppression matching.
