Daniel Marjamaki bf0386c938 Preprocessor: Started working on new preprocessing that uses -D information better. Ticket: #2131 2011-10-17 20:12:46 +02:00
Edoardo Prezioso c3caade3ca - Fixed mispelled function name;
changed variable name inside simplifyFlowControl for consistency;
improved simplifyFlowControl to handle better this kind of code:
"return; { { } { label : ; ok ( ) ; } }"->"return ; { { label: ok ( ) ; } }".

Thomas Jarosch a52b73f9f9 Fix #3208 (Simplify pointer to standard type, C only)
The symbol database is unavailable during token simplification
and &data[0] might return something completely different for C++.

Moved code_is_c() from checkOther to Tokenizer.

Thomas Jarosch 849bee8437 [PATCH] Detect suspicious use of semicolon after 'if/for/while'
statements if they are followed by a {..} block.

Examples are:

for (int i = 0; i < 10; ++i);
{
   printf("i)";
}

or

if (i == 100);
{
   die("Wrong argument");
}

This new check is active if you enable inconclusive checks.

Edoardo Prezioso 9270b84d64 More fixes to the label simplifier (related to ticket 3176):
1)Simplify the labels if there are combinations of the symbols '*','&','{' and '(' after a '%var% :' and before another '%var%';
2)but do not simplify the label if it's inside an unpreprocessed macro code.

Edoardo Prezioso fe4ce594ce Renamed the function 'removeRedundantCodeAfterReturn' with 'simplifyDeadCode'.
This is a preparation in order to add new features to this function (see the @todo in the tokenize header file, ticket #3113 and #3175 for details).

Kimmo Varis 3cfe7ca1a7 Move "information" errors to "style" errors.
"information" severity is documented in lib/errorlogger.h as:

  Checking information.
  Information message about the checking (process) itself. These
  messages inform about header files not found etc issues that are
  not errors in the code but something user needs to know.

It IS NOT for errors in the code. All the current "information"-
severity errors fit nicely into description of the "style"-
severity.

We definitely need to separate processing information and actual
errors in the code. It is highly confusing for users to mix these
two different things. Hence all current "information" code error
messages are moved to "style" category.

Ticket: #3165 (Stop misusing the 'information' error severity!)

Edoardo Prezioso 8e90ad106c Fixed ticket #3148 (Analysis failed on "Modules/mathmodule.c")
Fix: Do not handle code when 'return' is inside a macro. This is valid also for 'switch' code inside a macro.

Edoardo Prezioso 3c370dcfdf Fixed #3146 "Analysis failed" error on softmagic.c:
-Fixed: the code didn't check the rightness of the switch syntax if it was inside another switch;
-Tweaked: removed the two bool variables, so now the conditions take count of indentation unsigned variables.

Kimmo Varis 4ef4cb26e9 CLI: Add support for ignoring case in PathMatch.
