Bug ID: 46160
Summary: Failure to optimize out redundant compare
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: gabrav...@gmail.com
CC: llvm-bugs@lists.llvm.org
bool f(int a, int b, int c)
{
return (a == b) && (b == c) && (a == c);
}
This can be optimized to `return (a == b) && (a == c);`. GCC does this
transformation, but LLVM does not.
