Stefan Weil 00ead7fb2e support any number of --append=<file> options
If one or more append files are given on the command line,
they are simply concatenated.

Stefan Weil 785bc3d04b Optimize handling of --append=<file> option (execution time, memory)
Whitespace was removed from the append data for every configuration
and every file: n(configuration) * n(files).

Removing whitespace immediately after the append data was read can
significantly reduce the execution time and memory usage.
It also allows further improvement because copies to the temporary
object appendCode are no longer needed.

Thomas Jarosch a645235d5a Adapt Token::strAt() to return a const reference like Token::str() does
Saves us a complete conversion from string.c_str() back to std::string.

Edoardo Prezioso 2c64d299ca Change every 'tokAt(...)->str()' to 'strAt(...)'. 2011-11-13 13:10:59 +01:00
Edoardo Prezioso b28a44dc3b Change: 'next()->next()'->'tokAt(2)', 'previous()->previous()'->'tokAt(-2)'. 2011-11-12 22:33:03 +01:00
Edoardo Prezioso ed6a0e14c4 Add simplification of the consecutive braces before the end of 'tokenize()' function. 2011-11-12 16:59:20 +01:00
Edoardo Prezioso 5cbfbe31c1 Add removal of consecutive braces, i.e.: '{ { ... } }'->'{ ... }'.
Changed a little bit the dead code tests.

Edoardo Prezioso 2aceb623ae 1)Add 'Token' function 'linkAt', which simplifies the writing 'tokAt(i)->link()' to 'linkAt(i)'.
It's still unused, though.
2)Fix one grammatical mistake inside token.h
3)Style change to token.cpp: remove the whitespace between '!' and 'begin'.

Thomas Jarosch 283c2e508e Remove check for "this" inside Token class
The check hides real memory problems and is
also useless in most cases.

Thomas Jarosch 1a454256dc Cache result of tok->isStandardType()
Also contains test order improvements from Johan Samuelson (#3116).

Run time went down from 15.15s to 14.95s for the case below.

Benchmarked using these settings:
- CXXFLAGS="-O2 -g -NDEBUG"
- time -p cppcheck.git -q --std=posix --enable=all --inconclusive -Dfoo .

on the "rpm" codebase.

Richard Quirk d1bc8819f9 Fix for same expression separated by commas
The code branch tested by the previous check for && is now different, so
I've changed the test to use == instead. There was also a missing case
when the expression was followed by a comma instead of being preceded by
one.

Richard Quirk 4cb97edbaf Improved same expression check for ticket #3274
Expand the logic for the check for the same expression on both sides of
the || and && operators. Now expressions can be more complex, with the
"alt" variable helping to fudge operator precedence to avoid false
positives.

Richard Quirk 7f88b66842 Fix namespaced types for auto_ptr new[] errors
This fixes false negatives for code such as:

    std::auto_ptr<foo::bar> p(new foo::bar[10]);

The idea is to find a "new", search for the end token ";", then see if
the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.

Thomas Jarosch 19c9c97608 Fix single %op% operator not working at all
When parsing the Token::Match pattern, we accesed
the wrong character in the pattern and never
executed the %op% check.

In addition the unit test function for %op%
wasn't registered in the test suite. Ups.

All fixed now and also provide a complete
check for all operators %op% supports.
2011-11-06 18:02:18 +01:00
Edoardo Prezioso 6e2f2816de Improve same expression check: remove '%op%' pattern and add ',' for the same expressions as an argument inside a function.
Improve compound assignment simplification: use already defined 'isAssignmentOp' and extend the adding parenthesis to a generic operator, not only to the arithmetical ones. See: http://en.cppreference.com/w/cpp/language/operator_precedence
