PKEuS d6cfbc6483 Improved checks in CheckStl:

- Reduced distance given to tokAt calls in CheckStl::redundantCondition
- Rearranged code in CheckStl::missingComparison to use more efficient comparision of varIds instead of variable names. Use varId in pattern instead of variable name.

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.

Reijo Tomperi 194327048a Add InternalError and change MathLib to throw it in case of an error.
- Previously MathLib errors did not provide a filename, but after this change at least source file name should be printed
and if token is provided, also line number should be printed.
- Change also Token to use InternalError
- Modify Cppcheck-class to catch InternalError instead of Token
- Run dmake to update Makefile

Edoardo Prezioso 99d8ce3732 Fix Valgrind error in arraySize():
if there's code like: 'int [ ] a = { 1 , 5 , }', 'end' is last '}', when 'tok2' arrives to second ',' and cppcheck finds out that next token to 'tok2' is '}', remove this ',' with 'tok2->deleteThis()' but it causes (maybe) a memory corruption to 'end' which will gave problems later because 'tok' will be assigned to it or its next token.
2011-12-12 02:23:49 +01:00
Edoardo Prezioso 52620e6493 Tokenizer::simplifyDoWhileAddBraces:
1)rewrite fix for ticket #988 (just don't simplify inside macro parenthesis);
2)use a different organization of the code: start from last token and proceed backwards. This way 'simplifyDoWhileAddBracesHelper' can be called just once, hence the 'Helper' code can be improved and moved in the main function.

Fix grammar mistake in comment.

Edoardo Prezioso 27801b35eb Other improvements to tokenizer code.
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 = { ... }'.

Richard Quirk a880469c5a Refactor the same expression check
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.

The pointer to symbol database and ref to list of const functions are
temporarily stored in  the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.

Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.

Richard Quirk d28cf42d4c Fix ticket #3317 (same expression false positives)
Add a check for function calls that have no side effects. That means
known const methods and a list including strcmp, strlen, etc.

If the function is not known to be side effect-free then no style
warning is given.

Add test cases for the duplicate expressions.
