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

Clarify a comment about previous commit.
2012-01-26 23:14:44 +01:00
Edoardo Prezioso 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.
2012-01-26 22:32:11 +01:00
Edoardo Prezioso b6763313c5 Tokenizer::simplifyQuestionMark: use links instead of indentation level number. 2012-01-26 17:55:22 +01:00

Robert Reif 4d56395504 symbol database: add simple try/catch tests 2012-01-25 22:48:18 -05:00
Robert Reif 6b0aff487f symbol database: add preliminary support for throw/catch block scopes. Just like the rest of cppcheck, ... is not handled properly for variables. Deep namespaces are also not handled properly yet. This is not an issue because this new capability is not used by any checks so it should be harmless. 2012-01-25 22:05:29 -05:00
