And it ICEs again with -O2 -fno-ipa-pure-const if I add [[gnu::const]]
or [[gnu::pure]] attribute to f.
The function seems to be const in that it only returns the result and doesn't
access any other memory,

-O2 -fno-ipa-pure-const helps though and the patch affected both.

--- Comment #5 from Andrew Pinski ---
But adding noipa to f does though:
[[gnu::noipa]]
std::optional f() { return 1; }

Hmm, even -fno-ipa-modref does not prevent the wrong code from showing up.

Testcase without the unneeded which aborts if miscompiled.
