Bug ID: 96232
Summary: Failure to optimize bool pattern equivalent to minus 1
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(bool x)
{
return x ? 0 : -1;
}
This can be optimized to `x - 1`. This transformation is done by LLVM, but not
by GCC.
