Bug ID: 94919
Summary: Failure to recognize max pattern
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) & -(x >= y)) ^ y;
}
This can be optimized to `x >= y ? x : y`. LLVM makes this transformation, but
GCC does not.
