--- Comment #9 from Segher Boessenkool <segher at gcc dot gnu.org> ---
The i386 port has
===
(define_insn "trap"
[(trap_if (const_int 1) (const_int 6))]
""
{
#ifdef HAVE_AS_IX86_UD2
return "ud2";
#else
return ASM_SHORT "0x0b0f";
#endif
}
[(set_attr "length" "2")])
===
which implements __builtin_trap, and can implement __builtin_trap_no_abort
just fine as well, if your OS kernel (or similar) can return after a ud2.
If clang uses terribly confusing names (or semantics, or syntax, etc.) we
should not copy that from them. *Especially* when that already conflicts
with names they copied from us.
