2015-06-23Fix some issues in TRUTH_ANDIF_EXPR analysis.Andrei Karas1-0/+6
2015-06-23Combine analysis code for IF_STMT and COND_EXPR into same function.Andrei Karas3-95/+38
2015-06-23Use same code in IF_STMT and COND_EXPR.Andrei Karas2-38/+41
2015-06-23Fix some scope issues. Can be tested with future test 21.Andrei Karas2-2/+10
2015-06-22skip nop node in DECL_EXPR.Andrei Karas1-1/+1
2015-06-22Add test 20.Andrei Karas6-1/+1426
2015-06-22Add test 19.Andrei Karas5-0/+1028
2015-06-22Fix issue in related variables checks.Andrei Karas4-0/+43
2015-06-22Add support for related checks for "linked" variables.Andrei Karas5-49/+72
Example: void func(int *ptr1) { int *ptr2 = ptr1; if (!ptr1) return; *ptr2 = 10; } here will be no warning.
2015-06-22Remove possible variables for check for parents if need.Andrei Karas1-1/+5
Also dont report about null pointer with empty variable name. This can happend in autogenerated pseudo functions.
2015-06-22Update test results.Andrei Karas4-63/+51
2015-06-22Add test 19.Andrei Karas6-1/+656
2015-06-22In places where searched function parameters nodes (PARM_DECL)Andrei Karas2-5/+5
also search for varibles (VAR_DECL).
2015-06-22Add analysis for code like "type *var = parm"Andrei Karas8-10/+103
Now var can be checked for nulls too. Also extend debug logging.
2015-06-22Dont report null pointer if variable was directly used.Andrei Karas1-1/+1
For example: int *ptr2 = ptr1;
