PKEuS 808c3468c9 New check: detect suspicious comparison of string literal with char* variable
Bugfix: Update Token type when varId is set
2012-08-24 14:25:17 +02:00
PKEuS 76fbcce13f Restored (intentional) content of screwed up commits 1bcdf4ce3d and 674f7980d519712ff16d8f874dfe55a84deb4b5b:
- New check (Inconclusive): Array filled incompletely with memset/memcpy/memmove
-- This check only warns if the number of elements is given as size in bytes to memset, memcpy or memmove and if the size of an element is larger than 1 Byte. It does not warn for random numbers

- New check: Detect ineffective statements like '*foo++;' (Should be: '(*foo)++;')

Sorry for the inconveniences.

Arpit Chaudhary 7c8da17c44 Added check for detecting if a variable or number is shifted by negative right operand. Statements like:
int i = -1;
 a << i;

 would result in an error message stating undefined behavior.
