fix misspellings & gcc v3.4.6 warnings
...
1. fix typos / misspellings
- Fix misspelling within comments, variable/function names, stdout messages
- changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```. Alias old name (```stlBoundries```) to the new one.
2. fix gcc v3.4.6 32bit & 64bit warnings
- fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html
http://stackoverflow.com/q/670308
- in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others

Small refactoring to compile more matches
...
*** Timing of the test suite ***
Four runs were used to calculate the average run time.
Before: ~1,103s
After: ~1,066s
Speed up: 3,35%
*** Timing of internal projects using STL ***
Before: ~8,301s
After: ~8,207s
Speed up: 1,13%
So the real world speed up is roughly 1%.

Adapt Tokenizer::simplifyCallingConvention() and Tokenizer::simplifyKeyword() for the match compiler

This little change gives another 6% speed improvement on my box.
(tested with the testsuite and checking the 'rpm' codebase)
The profiler showed we were spending quite some time in
Tokenizer::simplifyCallingConvention(). The multi match
pattern in there is "complex", at least for the on-the-fly parser.

Properly implement %op% for Token::multiCompare
...
Use tok->isOp() instead of doing it "manually".
This fixes false positives for the C++ template case since
the brackets in "template < something >" are not comparison operators.
Profiling showed using tok->isOp() is actually faster than before (-O2).
2013-01-09 17:05:53 +01:00
8b2adf1391
Change location of %op% operator in multicompare
...
When the %op% operator is the first element
of a multicompare, it properly executes Token::isOp().
Otherwise it uses it's "internal implementation".
Workaround inspired by Edoardo Prezioso.

Simplify some generalized math formulas:
...
Now the 'sin^2+cos^2=1' and the 'sinh^2-cosh^2=-1' code can handle, for example: sin^4+cos^4=1, sinh^10-cosh^10=-1.
Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.

Use more Effective C++ code style in SymbolDatabase class:
...
1)The SymbolDatabase::findScope code is moved to the const-version. The non-const version is reimplemented as the combination with const_cast and static_cast.
2)Unrelated: change style of the declaration of some functions (the '*' is moved near the function name).

Use more Effective C++ code style in Token class:
...
1)The non-const version of Token::tokAt and Token::linkAt now will use a combination of const_cast and static_cast to remove duplicate code.
2)The non-const versions of Token::find(simple)match are added, in order to avoid the usage of const_cast outside the Token code.
3)As a consequence of 2), an useless const_cast applied to a call of Token::findsimplematch in Tokenizer code is removed.

Add some unused private copy ctors and operator=.
...
In Token and in Check classes, GCC -Weffc++ reports that it's better to override the copy constructors and the assignment operator to avoid problems with copied objects which could have the same pointers, hence with double frees, when we delete one of these pointers in the copied and in the original object.

Token::Match: add a new pattern: '%comp%'.
...
Token::Match returns true if the token is a comparison operator. It's equivalent to matching '<|<=|==|!=|>=|>' and the tests show that the new pattern speeds up the program execution. Added the new pattern in CheckInternal (and also reordered the %cmd% lists) and in TestToken.
