-> 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.

PKEuS e80104327a AST: Fixed detection of operator new/delete - don't hang when C code is checked as C++ (#5910) 2014-06-26 09:19:57 +02:00
PKEuS b20f87faf2 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
PKEuS 360fd4a565 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.

PKEuS 188f9b4509 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

2014-06-14 12:38:02 +02:00
PKEuS 8b9daadd25 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)
