Alexander Mai 8d2c4453ad Small optimizations for C code in Tokenizer. Add some regression tests for recently fixed results 2015-08-29 19:00:09 +02:00
PKEuS 70368a2e3a Made ctor of triplet explicit, because cppcheck demands it. 2015-08-29 11:13:03 +02:00
PKEuS d5bc3285b9 Move "extern" to the beginning of a declaration like "static" and "const" 2015-08-29 10:57:52 +02:00
PKEuS f89205064a Several small optimizations in tokenize.cpp 2015-08-29 10:46:51 +02:00
Daniel Marjamäki 498c920180 addons/cert.py: better handling of structs. read pragmas in the file. 2015-08-28 18:07:12 +02:00
PKEuS 2ace3d3144 Rewritten handling of declaration specifiers:
- Removed simplifyConst() because it did the opposite of the (superior) simplifyStaticConst()
- Execute simplifyStaticConst() in simplifyTokenList1() - there is no reason to defer it, and it is required to properly parse declarations like "unsigned static int i;"
- Fixed simplifyStaticConst() to handle more patterns. It did not work at the beginning of the token list and for function arguments
- Reimplemented Tokenizer::simplifyStdType()
-> properly support all possible ways to declare integers as requested by the standard, instead of only a few common permutations of "unsigned|signed", "short|char|long|int"
-> Fixed parsing of _Complex/complex types

PKEuS 188096665c Implemented support for rvalue references (C++11):
- Split up && when it is part of an rvalue reference declaration
- Added support into symbol database
- Current implementation sets Variable::isReference() to true also for rvalue references - they can probably be treated like normal references in many checks.

Changed behaviour of symbol database: Insert argument Variable of functions that are not implemented into SymbolDatabase::_variableList

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "

2)The non-const versions of Token::find(simple)match are added, in order to avoid the usage of const_cast outside the Token code.
3)As a consequence of 2), an useless const_cast applied to a call of Token::findsimplematch in Tokenizer code is removed.

Edoardo Prezioso 1951d1cdc5 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

if 'endAt' is 'NULL' after finding the ';' token, exit the function;

2012-09-20 21:45:16 +02:00
Edoardo Prezioso eb5a61edfe Tokenizer: some changes to the code:
be sure '?:' ternary operation has whitespaces around the operators;
remove useless loop to get the 6 next tokens, use tokAt(6);
add '?1:0' to bool values when doing a sum with them.
remove useless 'enum' pattern checking in code executed after simplifyEnum;
after being sure the 'tok' is a standard type, begin the loop with the token next to it;
it's possible to remove two tokens before the current one without moving this.

PKEuS 35d94c26d5 Changed creation of SymbolDatabase. Database always created after Tokenizer::tokenize() and Tokenizer::simplifyTokenList() instead of on-demand creation by Tokenizer::getSymbolDatabase.
-> With Token::scope() it is possible to access the symboldatabase without having to call getSymbolDatabase(). The change increases safety because it is guaranteed that the database is available in all checks, even if the specific check doesn't call getSymbolDatabase
- Tokenizer::_symbolDatabase does no longer have to be mutable -> Increased const correctness

The change above required two additional changes:
- A bug causing a debug message was fixed in the symboldatabase that became visible in the test suite by the change above.
- Simplify expressions like "struct struct Foo" which might be result of typedef instanciation.
2012-08-12 03:01:24 -07:00

- Fixed two nullpointer issues shown by cppcheck

PKEuS e0a3ca0845 Refactorizations in class Token: changed handling of different types of tokens.
- Replace _isNumber, _isName, _isBoolean attributes by a single _type attribute (enum Token::Type), because not two of the old booleans could be true at the same time.
-> Add support for lots of different other kinds of tokens. (More precise checking of token type possible)
-> Replaced instant checking of type for Operators, etc. by a value calculated at creation time. (Faster checking)
2012-04-23 21:05:26 +02:00
PKEuS 8cbed66089 Changed relationship between templatesimplifier and tokenizer:

Removed ctor and dtor implementation from TemplateSimplifier: This class shouldn't be instanciated.

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.

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  (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.

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 = { ... }'.
