Note this might be already fixed by:
https://gcc.gnu.org/pipermail/gcc-patches/2023-June/622984.html
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=d915762ea9043da858d388b60b2d8093ff77eeab
Once I reduce the testcase, I will retest it to see if it has been fixed or
not.

Reduced testcase:
```
void f(float *a, float *b, float *c, int size)
{
float t[2];
t[0] = b[0] - (float)__builtin_pow(c[0], 2);
t[1] = b[1] - (float)__builtin_pow(c[1], 2);
a[0] = t[0];
a[1] = t[1];
}
```

Yes it was, going to add a testcase and close the bug as fixed.

https://gcc.gnu.org/g:857e1f93ff8e3b93a7a3dcca9e50fe32a4c93950
commit r14-2151-g857e1f93ff8e3b93a7a3dcca9e50fe32a4c93950
Author: Andrew Pinski <apinski@marvell.com>
Date: Wed Jun 28 00:21:08 2023 -0700
Add testcase for PR 110444
This testcase was fixed after r14-2135-gd915762ea9043da85 and
there was no testcase for it before so adding one is a good thing.
Committed as obvious after testing the testcase to make sure it works.
gcc/testsuite/ChangeLog:
PR tree-optimization/110444
* gcc.c-torture/compile/pr110444-1.c: New test.
