Bug ID: 52168
Summary: Failure to optimize 128-bit division
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations

__int128 b(__int128 j)
{
return j / 5;
}
This can be inlined into a series of operations avoiding the division, but LLVM
just outputs a call to __divti3. GCC does this optimization.
