https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89035 --- Comment #2 from David Brown --- Yes, "int x = x;" does give an unspecified value without a warning. But to me, this looks much more like a workaround - while "int x = __builtin_unspecified();" is clear in its intentions.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89035 --- Comment #1 from Marc Glisse --- We already have int x = x; for one of those, no? Or just int x; but it tends to warn.
