Store Token::_originalName on heap, since it is only used for a small amount of Tokens (reduce memory usage of TokenList by ~12% (x64))

Refactorizations optimizing std::string usage:
...
1) Added global static const std::string emptyString; object:
-> Replaces some static variables in functions which might be not threadsafe
-> Avoids constructor call (std::string::string(""))
-> Even functions that return an empty string in some branches can return by reference now.
Added to config.h to ensure that it is available everywhere
2) Added overloads for TestFixture::assertEquals for the most common use cases:
-> Moves conversion from const char[] to std::string into a function, reducing code duplication in binary.

Speedup checking large amounts of arrays ( #5615 ) by avoiding Token::Match calls in CheckBufferOverrun::checkScope(2).
...
-> Decreased entire checking time on a subset of the attached file by 66% (MSVC12, x64, non-matchcompiled)

Optimized Tokenizer::simplifyPlatformTypes() once more: Another 3% improvement on Windows.
...
-> All Token::Match strings are uppercase, so check Token::isUpperCaseName() to avoid comparisons with very slow long Token::Match strings (idea from amai)
Removed duplicate Token::Match call in symboldatabase.cpp
2014-06-25 20:42:59 +02:00

Speedup Tokenizer::simplifyMathFunctions() and Tokenizer::simplifyPlatformTypes()
...
-> Speedup on entire checking time (TortoiseSVN code) by 3% (MSVC12, x64, not matchcompiled). Probably only measurable when checking code with Windows platform.

Cache results for TokenList::isC() and TokenList::isCPP() to avoid redundant calls to Path::isCPP()/isC(), which perform slow string operations (conversion to lowercase, substring, comparisons)
...
-> Speedup of 2% on self-checking cppcheck-core (MSVC12, x64, not matchcompiled)
2014-06-24 17:42:39 +02:00

Fixed #error handling:
...
- Reporting them once is enough
- Don't report them if --force is used - since we silently drop these configurations when we check multiple configurations. Without the fix, -f combined with -D resulted in #error being shown erroneously.
- No redundant preprocessor instance to report them

Ticket #5868 : Ignore variables called like a typedef when substituting typedefs
2014-06-14 12:38:02 +02:00

Replaced static variable isCPP in Token (was not threadsafe):
...
- Encapsulate parameters passed through AST compiler functions in a struct
-> Reduces maintenance overhead when changing them
-> Contains parameter indicating if the file is C or C++
- Added eKeyword Token type (at the moment, only true for C++ keyword "delete", but should be set for other keywords as well)
