Bug ID: 114003
Summary: Missing MIN/MAX
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: missed-optimization
Severity: enhancement
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Take:
```
int f(short a, short b)
{
if (a > b)
{
int aa = a;
int bb = b;
bb++;
int t = aa > bb ? aa : bb;
return t;
}
return 0;
}
```
This should be optimized to just:
```
int f0(short a, short b)
{
if (a > b)
{
return a;
}
return 0;
}
```
As if a is equal b+1 (that is the only case where a>b matters), then
`extend<a>` and `extend<b>+1` are still equal.
