Bug ID: 95924
Summary: Failure to optimize some bit magic to one of the
operands
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: ---
bool f(bool a, bool b)
{
return (a | !b) ? (~a & b) ? 0 : a : 0;
}
This can be optimized to `return a;`. This transformation is done by LLVM, but
not by GCC.
