Bug ID: 95187
Summary: Failure to optimize bool check into consecutive
literals
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 b)
{
if (b)
return 1;
return 2;
}
This can be optimized into `2 - (int)b`. LLVM does this transformation, but GCC
does not.

Or expand phiopt to use match and simplify and then it is a job for match.pd.
I have a patch which does both really.
