Daniel Marjamäki bbb707c460 Fixed #3587 (Wrong tokenizer simplification - variable assigned by operator>>) 2012-02-07 08:05:50 +01:00
Daniel Marjamäki 47c7e346aa Uninitialized variables: Another fix for false positives when it's known that inner conditions are true 2012-02-06 19:26:28 +01:00
Daniel Marjamäki 05fc77c347 Revert "Uninit var: Added TODO test case"
The test case was not valid because the variable assignment is redundant and is therefore removed by the tokenizer.

This reverts commit 548a43fc49.

Handle SQL code better, even when there's no ';' after 'EXEC SQL'.
simplifyVarDecl: Check with 'Token::Match' once when you have to check a pattern inside which there should be a number or a variable. Use '%any%' and after that check if that string is a number or a variable name later.
simplifyGoto: process also anonymous structs and unions which should have 'indentspecial' incremented, skip code like 'var = { ... }'.
