a9d56f2738 Tokenizer: simplify known variable value inside conditional block 2012-03-12 17:32:30 +01:00
Daniel Marjamäki

1747813a8b Added check for invalid pointer casts (#1255) 
Detect sign extension problems when variable is a reference (#3637)
Refactorizations:
- Tokenizer::getFiles returns a reference instead of a pointer, because its guaranteed that no nullpointer is returned
- Remove signed/unsigned in one step for "%type% signed|unsigned"
- Fixed recently introduced compiler warning in symboldatabase.cpp

9431fb1b7e Improved STL checks:

9df6088ddd Revert "really fix #3527 (Internal error. Token::Match called with varid 0. Please report this to Cppcheck developers)" 
This reverts commit a37031944e5d26f169e2026aec182b5aae7bc88d.

I don't want this hard coding of macro names. Feel free to come with a more generic solution if you want.

fa77f98b1c Tokenizer: it's possible to set null lower bound for eraseDeadCode when used inside simplifyFlowControl. 
Remove now unused 'beginindent' and moved 'goto' simplification together with 'return' group.

0f1f3c0f5f Tokenizer::removeRedundantCondition: refactoring due to various reasons. 
1) Remove the dead code with 'eraseDeadCode', not with 'eraseTokens' because of the possible presence of labels.
2) It's impossible that in tokenizer there is pattern like 'if (true|false) {code;} else if (cond) {code_cond;}' because the function 'Tokenizer::elseif' adds '{' between 'else' and 'if', hence a code path is redundant, so it's removed from code.
