Miika-Petteri Matikainen 26816ed954 Fixes preprocessor regression causing hang
Cppcheck 1.76 introduced a regression in preprocessor which causes
the following code to hang:

    $ cat > test.c << EOF
    #ifndef Y
    #else
    #endif
    EOF
    $ cppcheck -D BAR --force test.c
    Checking test.c ...
    ^C

This used to work with version 1.75. Git bisect reveals that this
regression was caused by commit:
ff036c8742

This commit fixes the regression by avoiding infinite loop in
hasDefine(). If cfg is empty string "", we can skip the whole loop
and exit early.

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.
