Bug ID: 46116
Summary: Failure to optimize `(a + c) < (b + c)` to `a < b`
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
int f(int a, int b, int c)
{
return a + c < b + c;
}
This can be optimized to `a < b`. This transformation is done by GCC, but not
by LLVM.
