Bug ID: 96697
Summary: Failure to optimize mod+div to 0
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: gabravier at gmail dot com
Target Milestone: ---
int f(int x, int y)
{
return (x % y) / y;
}
This can be optimized to `return 0;`. This transformation is done by LLVM, but
not by GCC.
