PKEuS 7ea7ee0005 Store Token::_originalName on heap, since it is only used for a small amount of Tokens (reduce memory usage of TokenList by ~12% (x64)) 2014-06-26 11:51:02 +02:00
PKEuS ec1bd420a7 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.
2014-06-26 11:51:02 +02:00
PKEuS feefa4c626 Speedup checking large amounts of arrays () by avoiding Token::Match calls in CheckBufferOverrun::checkScope(2).

PKEuS e80104327a AST: Fixed detection of operator new/delete - don't hang when C code is checked as C++ () 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

Ticket : Ignore variables called like a typedef when substituting typedefs
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)

Sam Truscott 3d0524ecc6 Update the detection of the arguments in Qt's invokeMethod.
invokeMethod can invoke functions by name (string) rather than a
direct function call (i.e. reflection). The old code wasn't
correctly parsing out the argument which contained the name
of the function to call.

This resulted in that function being reported as unused when it is.

possibly introduced by over-optimizing compilers:
An explanation why the compiler could produce bad code here is found at
