Bug ID: 26889
Summary: clang doesn't warn about duplicated conditions
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: ahata...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
clang should warn that condition “a == 2” is duplicated in the following
if-else-if chain:
int g1;
void foo1(int a) {
if (a == 2)
g1 = 32;
else if (a == 3)
g1 += 23;
else if (a == 2)
g1 -= 123;
}
gcc6 added a command line option -Wduplicated-cond to catch this.
