fix misspellings & gcc v3.4.6 warnings
...
1. fix typos / misspellings
- Fix misspelling within comments, variable/function names, stdout messages
- changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```. Alias old name (```stlBoundries```) to the new one.
2. fix gcc v3.4.6 32bit & 64bit warnings
- fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
- in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
- this is the only ```vector<bool>``` in the codebase
- ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html

Fixed a bug in Tokenizer::simplifyKnownVariables.
...
When we find constant variables, check if there's a usage of its reference in the code (for example: don't simplify 'f(&x)' to 'f(&100)').

CheckMemoryLeak: add '?1:0' to clarify the value of the argument to 'deleteNext'; Tokenize.cpp: in simplifyCompoundAssignment(), remove ':' odd code used to fix a weird test case ('case' code not inside a function body), remove useless 'tok->next() != NULL' check (already true by previous condition); in simplifyConditionOperator(), handle better the parenthesis skipping code and remove useless ')'check; in simplifyQuestionMark(), remove useless 'tok->tokAt(-2)' check (Token::Match returns false if the token is NULL), add more patterns to Token::Match to handle more test cases; in simplifyBitFields(), add 'const' to 'offset' bool. RedirectOutputError: style nitpick change to declaration of a pointer.

Tokenizer: improve the new 'skipTernaryOp' function by supporting GCC '{(var|num;)}' statement expression extension; improve 'Tokenizer::simplifyQuestionMark' by supporting simplification with 'case' before ternary operation, using skipTernaryOp to get colon and, most importantly, supporting indented '?:' operations.
2012-10-13 02:32:43 +02:00
d4a3c1617a
Fixed: Tokenizer::simplifyLabelCaseDefault was careless with '?:' operator near 'case' adding the semicolon after the ternary colon.
