Revert "Change location of %op% operator in multicompare"

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.

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.
