Bug ID: 64250
Summary: Missing warning for "if (AA && AA)" / same expression
multiple times used
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: mpolacek at gcc dot gnu.org
Related to PR64249.
The following code gives the cppcheck warning:
[foo.c:2] -> [foo.c:2]: (style) Same expression on both sides of '&&'.
I couldn't get GCC to warn for this. (Real-world code, I assume it should be a
check for 'a' 'l' 'l'.)
Similar: A check for "||".
int foo(const char *argument) {
if (argument[0] == 'a' && argument[0] == 'a' && argument[0] == 'a')
return 1;
return 0;
}
